What is an Ion?

What is an Ion?For any student entering the chemistry classroom, he must be able to define ion. There are various ways by which students can easily know what it is. In this article, we are going to look at some important reasons why it is so important to learn about this fundamental component of the universe.Definitions are great. Whether it is scientific or social, people are always eager to know what they are talking about. Without understanding something, you are not sure of knowing something else that is very important. This is the reason why a lot of people spend a lot of time in understanding their definitions.If you are just a beginner and you want to understand something about your whole life, then you have to learn all the definitions for the subject, no matter how simple or complex it is. If you want to understand your environment, you need to define ion and other important ions. This is because there are so many different definitions for these two components. They are very important, and every student should have them at his fingertips.Ion is a universal element. No matter where you go, you will find these two elements. Although it is used for most of the science, science is also a big industry nowadays, where the chemicals and the drugs are made from different kinds of minerals and some are made from matter as well. Not all of the minerals come from nature, and some of them are manufactured by man as well.Other than science, it is also the basis of the theories used in biology and medicine. This means that it is the connection between cells, atoms, molecules, and the energies that they have. An individual who studies and researches chemistry would definitely know what an ion is.Chemistry requires it, since it is a science. For this reason, they always offer ion in chemistry as a requirement for the students to understand the subject. If you study with an exact definition, then you will be more prepared for your chemistry classes. If you do not know anything about this component, then you will just be a big waste of time.If you want to know what an ion is, you must know what the different definitions are for it.

Sum of Normal Distributions

Sum of Normal Distributions A normal distribution is a probability distribution which can be clearly represented using a bell curve. A standard normal distribution is also a normal distribution, however the mean of such a distribution is 0 and the standard deviation is 1. A bell curve, also known as the normal distribution curve is a graph which depends on factors such as the mean and the standard deviation of set of real numbers. The z-score value of normal distribution is given by a formula which depends on the mean standard deviation and the normal random x value. Example 1: For a set of random variables, given the normal random variable to be equal to 15. If the mean of the given set is 5 and the standard deviation is 2, then what is the standard score or the z-score? Given, x = normal random variable = 15 Mean, = 5 Standard deviation, = 2 The z-score = (x )/ This implies, z-score = (15 5)/ 2 = 10/2 = 5. Therefore, the standard z-score is 5. Example 2: For a set of random variables, given the normal random variable to be equal to 24. If the mean of the given set is 18 and the standard deviation is 3, then what is the standard score or the z-score? Given, x = normal random variable = 24 Mean, = 18 Standard deviation, = 3 The z-score = (x )/ This implies, z-score = (24 18)/ 3 = 6/3 = 2. Therefore, the standard z-score is 2.

French Vocabulary Hacks How to Tell if a Word is Masculine or Feminine

French Vocabulary Hacks How to Tell if a Word is Masculine or Feminine Suzy S. How can a word be masculine or feminine, and how do you tell the difference? Tutor Willy M. shares some secrets to help you memorize your French vocabulary One of the hardest things for many students of French to learn is how to tell the difference between masculine and feminine French nouns.  Gender with regards to words is not something we spend a lot of time thinking about in English, but in French vocabulary every single noun will have either a masculine gender or a feminine gender. Words that use the articles  le  or un  are going to be masculine, and words that use the articles  la  or une are feminine. Sometimes assigning gender to a word might seem arbitrary, but there are a few tricks that will help you tell if a word is masculine or feminine. The best place to start is by looking at the end of a word. Common Feminine Endings There are several endings that will clue you in to a words gender. For example, feminine nouns typically end in the letter “e.” Consider these word endings: esse, enne, euse, orde, anche, ouche, etc. If you notice a word that ends in -e, most of the time that word is feminine. So if you are taking a French test and the teacher wants to confuse you by giving you a word that starts with a vowel, you might see the word lactrice.  An article with an apostrophe can be confusing when trying to determine gender. But if you notice that the word ends in an e, or in this case the ending is â€"ice, you can guess (correctly) that this word is feminine. One other thing that I have noticed about feminine French vocabulary words, is that they also sometimes end with an â€"a. These words tend to be words that came into French from Arabic speaking colonies of French. They are often the French adaptations of Arabic words. Common Masculine Endings There are a couple exceptions to the ends in e rule.  Typically words that end in â€"ege, eme, ome, aume, age and â€"isme are masculine. The following endings also tend to be masculine: an, ent, ai, ou, et, eu, ut, is, â€"il, and ex. There are some endings that are typically masculine such as â€"on, but if you find it coming after a letter s or the letter c, it will often be feminine. Nouns that end in consonants like t, x, d, l, f, m or s, etc. tend to all be masculine words. So if you are taking your French test and you see a word like refus, a refusal, you can see the s at the end and make an educated (correct) guess that it is le refus. So now you have a few tips to help you identify the gender of French nouns. I hope you keep studying and put your French to good work one day.

6 Awesome, Unexpected Cover Songs You Need to Hear

6 Awesome, Unexpected Cover Songs You Need to Hear Suzy S. Singers, why limit yourself to one genre? Many artists have produced amazing cover songs to put their own spin on tunes, even those not in their particular genre. Here, St. Augustine, FL voice teacher Heather L.  shares six covers worth a listen How amazingly awesome is it to hear a song re-sung by a singer in a way thats totally unlike the original version? The correct answer? Really amazingly awesome! Sometimes it can change the way we hear the lyrics completely, sometimes itll make us laugh or cry, and sometimes, its just plain mind-blowing! Some songs might just showcase another artist, while others bend genres and provide a whole new sound and feel. If youve ever heard metal covers of pop songs, you know what we mean! Below are some of the best cover songs ever enjoy! I Will Survive Originally performed by Gloria Gaynor, covered by CAKE This may be the weirdest, most unexpected cover song of all time. Gloria Gaynor sang the original survivor ballad with elegance and soaring melody, and CAKE pretty much just reads the lyrics. And it couldnt be cooler! Shine Originally performed by Collective Soul, covered by Dolly Parton and Nickel Creek Post-grunge band Collective Soul had a big hit with Shine. But in this cool cover song, iconic country singer Dolly Parton jams with progressive bluegrass band Nickel Creek and takes it to another planet. And shes smart enough to cut out a couple of the superfluous yeahs that Collective Souls lead singer belts before the chorus. Rather Be Originally performed by Clean Bandit, covered by  Pentatonix The British electronic group Clean Bandit got their first number one hit in the U.K. just last year with Rather Be.   And the a cappella supergroup Pentatonix has already covered it and made it a hit of their own by using their voices in amazing ways to create the electronic sounds of the original.   Listen and try to hear how the vocalists make the drum, scratch, and bass noises! Jolene Originally performed by Dolly Parton, covered by The White Stripes Jack White is a huge fan of classic country, and his cover of Jolene is a real tribute sung and played with love. Dollys original is sweetly sung in her honey-coated voice, and Jack pretty much yells it. At least he plays the guitar intro the same way. Take Me Home, Country Roads Originally performed by John Denver, covered by Toots and the Maytals Even the most die-hard fans of John Denver, arguably the most popular country/folk singer of the 1970s, have probably never heard his music played by a reggae band. Its even more happy-go-lucky and smiley than the first one. Nothing Else Matters Originally performed by Metallica, covered by Tori Amos Metallica is the ultimate metal band of the 1990s, and Tori Amos is the ultimate girl-on-a-piano. What happens when she covers them? Cover magic! The words really shine through when youre singing them at half the tempo. And listen, she does. If nothing else, awesome genre-bending covers teach us that anything is possible in our craft and your creativity is only limited by your imagination. Einstein taught us that imagination is more important than knowledge. Well, heres hoping he was right! Readers, what do you think? Whats on your list for the best cover songs ever? Leave your favorites in the comment section below!   Heather L. teaches singing, piano, acting, and more in St. Augustine, FL, as well as through online lessons.

5 Steps to Ensure a Stellar Letter of Recommendation

5 Steps to Ensure a Stellar Letter of Recommendation The following is a guest post written by Anna Carapellotti of Admissionado, a premier college admissions consulting company focused on helping students get into their dream schools. Youve nailed down your school list, have a solid draft of your Common App essay, and feel like youre well on your way to being college bound. Now, its time to ask for letters of recommendation. A recommendation letter should be written by someone who knows of your strengths, personality, and accomplishments. These letters are taken seriously by admissions committees, as they are seen as candid descriptions of you and your character. Since you generally will not get to see what goes into your letter, here are some tips to ensuring you get a great one: 1. Ask early Whether your recommender is your teacher, coach, or manager, its important to keep in mind that theyre very busy. So, make sure that you ask them far enough in advance to give them plenty of time to actually write a quality letter. We usually recommend asking four to six weeks in advance, with four weeks being the absolute minimum. Particularly in high school, it becomes especially important to ask for your letters early, as most of your fellow students are rushing for the same deadlines and asking the same teachers, counselors, etc. for letters of recommendation. Asking early will not only ensure that your recommender has the time to put thought into your letter, but it will also show them that youre on top of your game, which could lead to an even stronger letter! 2. Ask someone who will write you a positive letter How can you know if someone would write you a good letter? Well, the first thing to consider is your memory. Do you have a good rapport with this person? Have all of your interactions been positive? If its a teacher, have you gotten good grades in their class? If its an employer or volunteer supervisor, have you performed well on the job? Is the work you have done with this person relevant to the program to which you are applying? If you have answered yes to most or all of the above questions, then chances are this person will write you a strong letter. Also, when asking your prospective recommender if they can write you a letter, consider gauging their response. If they say yes enthusiastically, then chances are their letter will reflect said enthusiasm. If they are hesitant, or if you asked them via email and they didnt respond, it might be worth it to ask someone else. [RELATED: 5 Things to Consider When Seeking Teacher Recommendations] 3. Provide your recommenders with all of the necessary details While it is important to give your recommender plenty of time to write the letter, dont ask them for such a favor before sorting out all of the details theyll require first. This could include the precise name and information about the university to which youre applying, the nature of your goals and how this program will help you reach them, a reminder of your relationship with the recommender (and how this relationship is relevant to what youre hoping to accomplish), when the letter is due, etc. If youve selected someone who is ready and willing to write you a good letter, then theyre going to need all of this information to do just that. 4. Waive your right to see the letter While Federal Law grants you access to your recommendation letters after youve been accepted to an institution, it is recommended that you waive your right to review them. You wont be penalized either way, but choosing not to waive might cause your recommender to write a less candid (and less passionate) description of you, or might signal to the admissions committee that you do not trust your recommender. If you have followed the advice laid out in sections one, two, and three, then you should feel completely comfortable leaving the rest up to your recommender. [RELATED: How to Survive the College Application Process] 5. Say thank you Obviously, this step comes after your recommender has written the letter, but its crucial dont forget to say thank you! And we dont mean a quick email. Write them a handwritten card. If they really went out of their way to support you in the application process, consider getting them a small gift, such as flowers, coffee, or chocolate. A great letter of recommendation can make or break your application, so be sure to show your recommender that you are truly appreciative. So, to recap, ask someone (early!) who will write you a strong recommendation, provide them with all of the necessary information, and dont forget to say thank you.

Should I retake my A Levels

Should I retake my A Levels The A Levels can be a make or break you thing for many students. They can determine whether you gain admission to the university of your dreams or any university for that matter. Also, A Level scores can hold you back from receiving the degree you want. If you don’t obtain high enough scores in the subjects you need for your degree, then you cannot pursue that career path. Call and check, it never hurts to ask! If you did not receive the scores you were hoping, don’t panic. Take a deep breath and consider some options you may have available to you. First, you should contact the university/universities that you were seeking admission to and ask if they have had many applicants to your field of study. If they have openings, you may be able to get in with your current scores. It never hurts to check! Retaking the A Levels Check to see if your school or college will allow you to resit your A Levels. If they don’t allow retakes, then look into other schools or college that may let you resit them. If you are considering retaking your A levels, you should talk to your teacher to see if they think you will do any better on your second attempt. Many students achieve better scores the second time around, however, everyone differs. Referring to your GCSE scores can also help in determining whether or not it’s worth it for you to retake the exams. Many schools and colleges use GCSE scores to predict how pupils will perform on A Levels. If you are planning to retake the exams, then you will need to officially decline your offers from universities in order to start the retaking process. A Levels can only be taken again during the summer, usually in June. You can talk to your Head of Sixth Form or class tutors to receive more information about retaking A Levels for individual subjects. What is the best decision for me? You should really think hard about if you want to retake the A Levels. If you truly gave it your best shot the first time and don’t think you’ll improve, why take it again and waste that time? Also, if you put forth your best effort on a subject you need for your degree and didn’t do as well as you were hoping, you should determine whether this career is the one for you or if you should pursue another path. Provide an explanation Don’t worry about universities judging you based on the fact that you took your A Levels again because declined A Level grades are not displayed anywhere. Although when you re-apply for the university/universities, you can explain why it has taken longer for you to  complete your A Levels in your personal statement. When applying for subjects such as medicine and veterinary science, most universities will not accept pupils who have taken 3 years to complete their A Levels unless there have been extenuating circumstances. Achieving the best possible scores can be difficult and very trying at times. Tutorfair has many tutors who are willing to help you as much as you need to help improve your scores and achieve your dreams. Didn't get at least a C in Maths or English GCSE?
