Superscript and Subscript Chemistry Symbols

Superscript and Subscript Chemistry SymbolsIn the world of chemistry, it is very difficult to avoid the use of superscript and subscript chemistry symbols. For example, a molecule or atom is marked with a superscript, while another atom can be marked with a subscript. An atom of the hydroxyl is superscript and one of hydrogen, carbon, oxygen, nitrogen, and carbon dioxide is subscript. Some people even say that the symbol 'x' is shorthand for the superscript and subscript.The reason why superscript and subscript are used in chemistry is that it gives you easier access to the names of atoms and molecules, and even abbreviations of scientific terms. It is common to see this kind of chemistry in many textbooks, and online there are many sites where you can find pictures, reviews, and information about chemistry symbols. Using the correct symbol can help you understand what you are reading and writing, and it will be easier to read information in print and online, and even on online chat rooms and email.However, the use of superscript and subscript chemistry symbols is not universal. If you are an American, then you may find this use of symbols less common in your textbooks and online. But if you live in Canada, UK, or Australia, you can find superscript and subscript chemistry symbols to be very common. The reason for this is that both the U.S. and Canada use a different set of symbols for these kinds of chemistry symbols.U.S. uses a combination of symbols for letters, numbers, and alpha and beta. They often use the symbol 'A' for all, or 'V' for beta. They also use both an 'x' symbol for superscript and an 'X' symbol for subscript. In Canada, the symbols 'Q'V' are used for their alphabetic characters.If you are not familiar with Canadian abbreviations, you can also look at a web site where you can find symbols like 'V' for certain nutrients, and a link to the United States Department of Agriculture website. Other symbols used by scientists in Canada include 'Z' fo r zinc, 'S' for sulphur, and 'O' for oxygen. Canada is also a member of the Organization for Economic Cooperation and Development (OECD), which helps standardize chemical symbols across most countries.Science is a science of objects, substances, and phenomena. Every phenomenon, substance, and object in the world have a name. This information is called symbols, which help scientists and other researchers keep track of their data.Using symbols is just the proper use of them. A good way to learn more about chemistry is to watch movies like The Secret which explains how symbols are used in chemistry. You will enjoy this kind of movie, because it will make you feel like you are part of the story and won't bore you.

Guitar Chord Charts 11 Easy Tips to Read Fingering Charts on Acoustic Guitars

Guitar Chord Charts 11 Easy Tips to Read Fingering Charts on Acoustic Guitars Suzy S. While its true that you dont need to read music to play the guitar, you should learn how to  read guitar chord charts. A guitar chord chart is a visual representation of a chord. This helpful visual is a little like music-by-numbers; it tells you which finger goes where  and on what string, so in case you come across a chord you dont know, youll  be able to play it. Heres an example of a guitar chord chart, also known as a guitar chord diagram: Guitar chord charts are a cinch to read once  you learn what all the lines, numbers, and circles mean. Are you ready to start learning how to play songs on the guitar? Here are 11 things you  need to read guitar fingering charts. 11 Tips for Reading a Guitar Chord Chart Visualization The grid of six vertical and five horizontal lines represents the  guitar fretboard. If youre having trouble understanding the basic layout of the  image above, hold your guitar in front of you so that the strings are facing you and  the headstock is pointing up. The image of the guitar chord chart represents this same view of your guitar,  with strings running vertically and frets horizontally. Which End Is Up? Guitar chord charts are  more commonly situated vertically (like above) rather than horizontally, especially  in songbooks. Its good to learn to interpret both vertical and horizontal grids  though. Righty or Lefty? Since guitar chord charts are  typically written for right-handed guitarists, they provide a challenge to left-handed players, who have to do a bit of re-visualization by flipping the chart  around. If a given source doesnt provide a left-handed version, you can download  left-handed guitar chord charts online. Chord Name The letter at the top of the chart is the name of the chord. RELATED: 20 Easy Songs with Basic Guitar Chords Vertical Lines The vertical lines on a guitar fingering chart represent the six strings of the  guitar. The low E string (the thickest one) is on the left of the diagram, followed  by the A, D, G, B and high E string, which is on the right of the diagram. The  string names are sometimes noted at the bottom of the guitar chord chart. Horizontal Lines The horizontal lines on the chart represent the metal frets on  the neck of the guitar. The top line will generally be bolded or marked by a double  line, which indicates the guitars nut. Fret numbers are sometimes noted to the left  of the sixth string. Chords Beyond the 4th Fret If the guitar fingering chart  is depicting frets higher than the fourth  fret, the top line on the chart will not be bolded (or doubled) and fret numbers will  be shown, either to the left of the sixth string or to the right of the first string, to  help orient you on the fretboard. SEE ALSO: How to Read Guitar Tabs Black Dots The black (or red) dots on the diagram tell you  which frets and strings to place your fingers on. The numbers inside the dots  indicate which fingers to use on each of the frets. They correspond to the four  fingers of the fretting hand. Number 1 is the index finger, 2 is the middle finger, 3  is the ring finger, and 4 is your pinky. You dont use the thumb to fret, except in  certain unusual circumstances. In those cases there would be a T inside the black  dot. Fingerings can also sometimes be found written along the bottom of the  strings of a chord chart, or between the nut mark and the chord name instead of  inside the dots. Xs and Os An X above the bolded nut mark indicates a string you dont  pick or strum. An O in the same location means to play the string open. Alternate Fingerings You may come across a suggested chord fingering that  you simply cannot contort your fingers to play. In this case try experimenting with  alternate fingerings. The most commonly used chord fingerings, however, will  work for most guitarists. How a Barre Chord Is Charted As you probably already know, barre chords  are chords that involve using one finger, usually your index finger, to hold down  multiple strings in a single fret simultaneously. A barre is noted on a guitar chord diagram by a curved or solid line running  through a fret from the first note to the last note of the chord, or by a series of dots  in the same fret that all bear the same number.

Intercept Definition - Online Tutoring

Intercept Definition - Online Tutoring The point of intersection of a curve of a function and the axes is known as its intercept. The intercept can be either x interceptor y intercept. X intercept is the point where the curve intersects the x axis. Y intercept is the point where the curve intersects the y axis. Example 1: Given below is the graph of the function y = 2x + 4. Find the intercepts of the function. Solution: The curve of the given function y = 2x + 4 is a straight line. The straight line intersects both the axes at two distinct points. The curve of the function intersects the x axis at x = - 2. So the x intercept of the given function is the point (- 2, 0). At y = 4, the line intersects the y axis . Thus the y intercept of the given function is (0, 4). Hence the intercepts of the given function are (-2,0) and (0,4). Example 2: Find the intercepts of the following function y = -3x 6. Solution:As we can see in the graph, the curve of the given function is a straight line. The line intersects the y axis at -6. Thus the point of intersection of the curve and the y axis is (0, -6). The curve intersects the x axis at x = - 2. Therefore the point of intersection of the x axis and the curve is (- 2, 0) Hence the intercepts of the given function are (-2, 0 ) and (0, -6).

Looking to Study Arabic Any Idea of the Best Way

Looking to Study Arabic Any Idea of the Best Way Learning to Speak Arabic: What to Study? ChaptersWhat Is Linguistic Immersion?The Arab World.Learning Arabic through ImmersionAiding Memory Through Arabic ImmersionThe Other Benefits of Learning Arabic AbroadThe 'Year Abroad': Going to the Arabic-Speaking World with University.The 'Home-Stay': Learning Arabic Locally.The 'Private Tutorial': Get Your Own Arabic Tutor.The 'Conversation Class': Join an Arabic Class - or Set One Up Yourself.The 'Self-Taught' Learner: Can You Learn Arabic by Yourself?What, then, Are You Waiting For?“Learning is not attained by chance, it must be sought for with ardour and attended to with diligence.” - Abigail AdamsLearning Arabic, like any other language, often happens in the same way if you learn in a school. You’ll learn some words, practise reading and writing, and it can be painfully dull at times.There are 22 different Arabic-speaking countries who are also members of the Arabic league.In 2014, the Arab League covered 13.5 million km ² and is home to 378 million Arabic speakers.What better place to learn how to speak in Arabic?In this article, we’re going to look at what linguistic immersion is, how you can use it to learn a language, how immersion aids memory and the benefits of learning a language abroad through immersion.But we're also going to look at some of the other ways to learn the language - those same ones that can be painfully dull, those that might help you get to where you need to be before you go abroad, and those that you can fit around your schedule seamlessly.University of Cambridge: - at Cambridge, you can do as you please for your year abroad - obviously within reason. Their students have travelled to Palestine, Oman, Lebanon, and Egypt, and usually return pretty satisfied with their experience.University of Edinburgh: - in a similar way, Edinburgh has no fixed destination to which you will travel, but, over the thirty weeks you will be required to spend abroad, the university will make sure that you keep working and improving with your la nguage.School of Oriental and African Studies, University of London: - on an Arabic course at SOAS, you can take a year abroad at one of three institutions: the Qasid Institute in Amman; the Alif Institute in Fez; or the Alexandria School of Languages, in Egypt.Years abroad are a fabulous way to hone your language skills - and it is the reason language degrees are usually an extra year long. And these years make these extra years well worth it.The 'Home-Stay': Learning Arabic Locally.One of the most rewarding options available to those seeking an Arabic language immersion programme is the home stay. If you haven't heard about these before, they sort of do as they say on the tin: you stay in an individual or family's home, and learn the language whilst you are experiencing local habits, ways of life, food, and routines.People who do something like this usually say it is one of the best experiences of their life - and it is the peak of that contemporary buzzword that drives travelers these days: authentic.There are many organisations offering these experiences these days, with options available in Oman, Morocco, Egypt, Jordan, Lebanon, and more. The prices vary dramatically by region and by organisation, but you could be paying as little as $60 a week and as much as $1000 a week too!If you want to bypass the organisation and get a cheaper rate, you can go direct to your host. However, this can be something of a risk, as the organisations both accredit the host and insure against any risk.The 'Private Tutorial': Get Your Own Arabic Tutor.If you're interested in learning how to speak Arabic, then private tutorials are a great option. On Superprof, you can get one on one private tutorials, online tutorials, or group tutorials.Private tutorials are the most effective and also the most costly. This is because your tutor will tailor the lessons to you, your strengths and weaknesses, and your preferred learning style. This means you'll get a bespoke service from them.S uperprof is a great place to find yourself an Arabic tutor, with over 800 available across the world. They charge an average of £17 an hour, and you can find native speakers, graduates, university students, and even academics available to give you tuition.They are qualified, experienced, and friendly, and they will have you speaking, reading, and listening effectively in no time.This is the best option for those of you who don't fancy traveling abroad just yet, or who don't have a sufficient grasp of Arabic for immersion to be productive. As, sometimes, it's helpful to have a basic understanding of the language before you dive in.Online Arabic Tutors.Online tutorials are similar but are cheaper because the tutor doesn't have to factor the cost of travelling to you into their rates. They'll deliver their private tutorials via webcam using a programme such as Skype.And honestly, these days, such technologies can facilitate as productive and helpful conversations as those had face-to- face. Talk to your heart's content - whilst you will be set up with homework, writing tasks, and solo research to do in your own time.If you are not in an area well-served by Arabic tutors, you can find - through Superprof again - and connect with more tutors than you could possibly imagine. Technology is awesome these days.So, if you are travelling to Morocco and want to polish your Moroccan Arabic, or if you are going to the Levant and want to brush the cobwebs off your Levantine, then connect with a tutor there who speaks the dialect, and you'll be talking away immediately.The 'Conversation Class': Join an Arabic Class - or Set One Up Yourself.Finally, it's worth mentioning that group tutorials have the advantage of being the cheapest per hour. This is because the hourly rate is shared by all the students in attendance.This also means that you won't get the same amount of attention from the tutor and the class won't be designed with just you in mind. But, that needn't be such an issue. The thing here is that people often learn better in group environments - building on different people's mistakes, hearing questions that they hadn't necessarily considered themselves, and enjoying the social element added to it.If there aren't any group classes or conversational classes in Arabic available in your home town, why not set one up? Get in touch with a Superprof tutor and see whether they are available and willing. It won't be good just for your language skills - but for your social life and your wallet too.The 'Self-Taught' Learner: Can You Learn Arabic by Yourself?This is a question that people often ask about learning languages:  can I learn it by myself?It's also a method that people think would be best, as they can study in their own time, at their own pace.It might even be possible with a language that is a little more similar to English - a language that shares the alphabet, that shares a few words, that has similar phonological patterns. Even then, with no -one to talk to or to ask questions, it's still pretty tough.With Arabic, you aren't going to enjoy any of the similarities that a language like Italian or German has with English. With Arabic, the alphabet, the sounds are incredibly dissimilar to English, and it is one that you may not have come into much contact with before.Sure, with all the resources available online and in books it might be  possible.  But it is far from preferable, and the challenge might prove too much.What, then, Are You Waiting For?If you are committed to learning Arabic, the last thing to say is, what exactly are you waiting for? The language is not going to learn itself!

Learning Maths at Key Stage 3 What to Expect

Learning Maths at Key Stage 3 What to Expect Help for Students Learning Maths in Secondary School ChaptersMath Concepts in The KS3 Maths CurriculumKey Stage 3 Maths ExamsFinding Help With Math Problems During KS3Key Stage 3 (commonly abbreviated to KS3) consists of years seven, eight and nine â€" so students from ages eleven to fourteen in secondary school in the UK.KS3 school maths is a pretty big and sometimes challenging journey, starting from year seven and ending in year nine before you embark upon maths GCSE, which is one of the mandatory subjects to take at GCSE in the UK.The jump from KS2 in primary school doesn’t have to be too scary, as you will be eased in at a comfortable pace, just building on from what you have been studying in your year six maths lessons.Key stage 3 maths is about learning to interconnect mathematical concepts that pupils can move between with ease and fluency. Being able to identify patterns and overlapping concepts in maths topics is key to KS3 progression.Although the maths topics in years seven, eight and nine are presented as distinct from o ne another on the school syllabus, students should be able to make connections across the topics and build upon prior key stage 2 knowledge to develop confidence and fluency in maths study.KS3 maths will also help pupils develop their mathematical reasoning and maths problem solving to a higher, more sophisticated level. Students will find that KS3 maths will enter into other subjects, applicable to science, ICT and geography, for example.KS3 maths can be applied to many subjects! Photo credit: Tim Geers via Visualhunt.com / CC BY-SAAs we’ve seen, maths can appear in other subjects that pupils will study during key stage 3. Certain topics in chemistry, physics, biology will no doubt contain some maths, and subjects such as ICT, geography or business, for example, could also contain some mathematical situations as well.So keeping up to speed and staying engaged with maths lessons isn’t just important for your mathematical progression alone. It will help immensely with subjects a cross KS3 study, especially with the natural sciences which will start containing more and more maths in the run up to GCSE.KS3 maths revision can benefit your other subjects too! Photo credit: CollegeDegrees360 via VisualHunt / CC BY-SAThe maths involved with physics, chemistry and biology can be quite tricky and requires extra attention sometimes. Pupils will see overlaps in these syllabi, and should therefore seek help or guidance as needed with any maths that seems challenging, regardless of the subject.SuperprofSuperprof, if you didn't know, is a platform that connects diligent students to experienced tutors. Right now, it has over six million tutors across the world - offering personal tuition in over a thousand different subjects, including maths and related subjects. So, whatever it is you want to learn - whether that's about equations or something else - you'll find the right person for the job (and for you!) with Superprof.Be sure to read about your prospective tutor and take advantage of the one free lesson policy so that you can get a feel for their teaching methods and work out if you think you will get along in a professional student-teacher manner.Remember, the cost does not always reflect the person's experience and qualifications (the cheapest tutors are not necessarily the least successful at teaching learners and the pricier ones are not always the top teachers) but, that said, you do get what you pay for so don't be reluctant to pay for a good tutor and then complain that you haven't learned what you had wanted to!If you choose a tutor who does not live nearby, the chances are that they will set you work by sending you questions and tasks electronically, and will also schedule some virtual face to face catch ups via Skype or  video call to ensure that you benefit from real-time interaction and instant feedback as well as simply being left to work things out for yourself.Additional Ways To Support Learning MathsYou don’t necessarily have to spend lots of money on books and website subscriptions to get ahead with your studies, as a range of educational books (including those specially-adapted revision guides) can be borrowed from libraries in your nearby towns.Of course, you won’t be able to make notes in the books you borrow, as they are officially the property of the library, but you can take the materials away to read or even to photocopy (many libraries offer photocopying services on site too so you could even have the opportunity to copy certain articles, exercises or definitions to put in your revision folder and go back to at a later date) and make your own revision guides.Most libraries are open for quite long hours so you can usually find a suitable time to visit around your busy educational schedule. As mentioned, you can read and photocopy relevant materials and even try to recall items that someone else has borrowed. In addition, many libraries now offer modern digital platforms, whereby online data and journals can be accessed and viewed.Your school may have their own library, however, you might find that the study areas get quite busy in the run up to exams. Also, the likelihood of relevant Maths books being available is quite low, since around two dozen (or more if you have a large year group) of you will all be working towards the same goal. That is why visiting libraries in and around your area is a wise idea.Discover how useful maths can be in life and why you should consider studying it.

Easily confused words in English Why the Butterfly Effect is not the Butterfly Affect

Easily confused words in English Why the Butterfly Effect is not the Butterfly Affect You have probably heard of the book and movie The Butterfly Effect, but do you know why it is not called The Butterfly Affect? These words sound the same, and are often confused by people learning English, and even by plenty of people who are native English speakers. EffectThe word effect is generally used as a noun in English. It refers toa result brought about by a causean impression of somethinga phenomenon, wither real or illusorymeaning or senseHere are some examples of its usage:The effect of the flooding on the house was clearly visible. The soothing music had a powerful effect on the child and lulled him to sleep. She put flowers on the table to create a homely effect. The pill had an immediate effect on my headache.Occasionally, effect is used as a verb. In this case it is used to evoke a change that has been brought about.Here is an example:Our school director changed the rules in order to effect a change on how we behaved ourselves.AffectAffect on the other hand, is normal ly used as a verb in English. It means to: change someone’s state emotionally or psychologically influence someone or something assume a behavior attack or infectHere are some examples of how it is used.Polio can affect sufferers’ legs and reduce their ability to walk.
