Powerful Ionic Compounds

Powerful Ionic CompoundsPolyatomic ions are neutral to positively charged molecules that contain one more electron than a normal molecular ion does. As such, they can form single or double bonds, depending on their types.Molecules containing double bonds have two hydrogen atoms and one proton between them. In contrast, single-bond molecules (those with a single bond) have two electrons between the proton and an atom's nucleus.Polyatomic ions with multiple charge cations are commonly referred to as strongly cationic ions. They have many negative charges and therefore cannot be neutralized. As a result, most chemical reactions with strong cationic ions will be unreactive, resulting in no harmful side effects. For example, a neutralizing agent would have a significantly higher effective surface area, resulting in faster degradation of the molecules being attacked.Among the polyatomic ionic compounds, the most widely used are zinc(II) complexes, but it is common to see the mildest polyat omic ions being used as strong ionic compounds in organic reactions. The main difference between them is how they behave chemically, which is largely determined by the elements they are made of.As strong ionic compounds, they are almost always sensitive to potential changes (the change in potential from ground state to an excited state). If the conditions are right, a chemical reaction can occur (as a result of the transfer of charge) with a potential that is much higher than the concentration of the molecules.Due to the molecular nature of strong ionic compounds, their most important advantage is that they allow the molecules to undergo conformational changes in very small amounts, thus facilitating controlled reactions. In other words, these ionic compounds can be converted into a more effective energy producing reactant.Although polyatomic ions are generally quite reactive, the strong ionic compounds can be advantageous due to their ability to retain a high degree of stability un der all conditions. In addition, ionic compounds are able to allow several chemical reactions to occur with the same molecule. This is important in organic synthesis, for example, as it is the low abundance of particular compounds that make different synthetic reactions less stable.

Algebra Mixture

Algebra Mixture We know Algebra mixture problems are problems which find a final solution by adding or subtracting of two or more results of the same problem. We have some steps to derive the solution. Step 1: from the problem, we can write an expression for some variables. Step 2: If we have two equations, from that we need find the solution, by adding or by subtracting of equations. Example 1:If the angles A and B are complementary angles. The angle A is 21 more than twice the other angles B. Find the angles A and B. Solution: The given angles are A and B. We know complementary means 90 From this we can write, A + B = 90 (1) From the problem we can write A = 2B + 21 Means A 2B = 21.. (2) From (1) and (2), we can write (1) (2) A + B = 90 A 2B = 21 - + - 3 B = 69 Divide this by 3, then we have B = 23. From problem (1), A + B = 90 A + 23 = 90 A = 67 The final answer is A = 67 and B = 23. Example 2: Robert and Peter started a business. In that business Robert invested $5000 and Peter invested $3000.Find the ratio of their shares. Solution: Roberts share amount = $5000 Peters share amount = $3000 The ratio of their shares = 5000: 3000 = 5: 3. Hence the ratio of their shares is 5:3

Helping Young Adult Excel Through Summer Programs - Private Tutoring

Helping Young Adult Excel Through Summer Programs BobbiM Jun 8, 2013 How can we Help Young Adults Excel Through Summer Programs? Summer is a time that virtually every child looks forward to all year long. While some individuals may view summer as an opportunity to lay around the house and sleep until noon every day others see a wealth of potential in allowing a child to grow through experiencing new adventures. Helping a child achieve personal excellence through participating in summer programs for high school students allows them to get ahead in life by learning something about themselves and developing their skills. These benefits will help them as they grow older and find themselves making decisions about their career choices as well as many of lifes other challenges. There are many different types of summer programs for high school students that are available. Many of these programs are specific to a given location. Parents who live in the area may wish to have their child participate in these programs or they may make the decision to send their children to programs in different areas of the country. It is safe to say that there is a program available for virtually every interest. There are also both short-term and long-term programs available which allows students to take advantage of a variety of different activities. Career Exploration Many summer programs for high school students help them to earn money. Students may also be able to take advantage of attending summer programs which allow them to explore a given career field as a means of determining their interests and further pursuing the profession. There are many summer programs available to help students decide what they want to do with the rest of their lives by giving them the opportunity to be directly involved in a profession for a period of time. This is accomplished through allowing them the chance to participate in the same activities they would be doing if they held this profession and giving them the chance to see what it is really like from a first-hand point of view. This type of experience can prove to be extremely valuable when helping young adults decide how they want to spend the rest of their lives. Traveling Students also have the opportunity to travel during many of the summer programs. The program itself may be designed to expose a student to other cultures and allow them to experience the way that people in different parts of the world live. This is often true of sponsored trips to other countries. Moreover, a student may have the opportunity to travel within the United States if he or she wishes to attend a summer program that is not offered locally. For example, individuals who are interested in participating in a summer program that involves researching marine mammals will have to travel to an area that offers such programs if they live in areas away from the water. This too proves to be a valuable experience because it allows students the chance to see if they can realistically expect to be happy working in a given profession as well as living in a different geographic location. Private Tutoring Some students may find that they need additional help with academic subjects in order to prepare themselves for college. Still others may wish to get a head start on their college career by learning subjects that are not offered to them through their local school system. In either case, hiring a summer private tutor to assist the student with his or her needs can prove to have a dramatic impact on academic performance later on. A summer private tutor can be hired locally or through a virtual tutoring program. There are many opportunities that are available to high school students in order to help them achieve success later in life. Summer programs and private tutoring are just two of the most popular avenues. High school students have a myriad of choices available to them regarding both their college and professional careers and making wise choices while they are out of school for the summer can help them to get ahead after they graduate from high school. In addition, taking advantage of the opportunities that are before them throughout the summer often enrich their lives in ways they could never have imagined. The chance to enhance existing skills and learn new ones while making new friends cannot be equaled.

Should I mention religion in my college essay

Should I mention religion in my college essay ACT SAT Prep and College Admissions Blog The short answer is this: it’s okay to discuss religion in your essay as long as the take-away (or values) promoted in the essay are universal. Here’s what I mean: In the past, I’ve had students write essay drafts that end with something like, “Since accepting Christ (or) learning to meditate (or) converting to Judaism, I’ve made it my goal to tell others about the difference that Christ/meditation/Judaism can make in their lives.” I call this the “missionary” essay. And it can be off-putting to readers, particularly to those who don’t share your religious beliefs (which, statistically speaking, is likely). Instead, discuss the values you gained through your religion. How? Step 1: Take a look at this Values List and ask yourself: what values have I gained through my religion? Examples: “Getting used to wearing a turban in ninth grade helped increase my self-confidence and, interestingly, my grades went up that year!” (or) “Feeling judged by my youth group leader helped me better understand how my friend must have been feeling about me; I realized I was essentially doing the same thing to her.” Check out those values: self-confidence and empathy. Nice! And anyone, no matter the religion or belief system, can get on board with those. Step 2: Make sure the values you’re discussing are non-obvious and specific. Obvious connections lead to boring essays. Examples: “Playing in the band at church helped me learn the value of working with others” (seen it!) or, “Volunteering at our mosque helped me develop myself personally” (super vague--say how!). Step 3: Get feedback from someone who does not share your religious belief. Once s/he has read the essay, ask the person: do you feel closer to me after having read that? If the answer isn’t “Yes,” or even if the person hesitates before responding, ask, “What would help you feel closer to me?” Step 4: Listen with your entire being. Stay curious. Step 5: Thank the person and go back to the drawing board. Because you are creative and original and you have something important to communicate.

CEO Interviewed by Dow Jones Journal

CEO Interviewed by Dow Jones Journal Tutorz.com CEO Dirk Wagner was interviewed by Dow Jones Journal Editor Missy Sullivan who is writing a story on the burgeoning online tutoring industry. During the interview Dirk provided a statistical data on the distribution of the main tutoring subjects. We are happy to be considered as one of the notable players in this market segment. says Dirk Wagner. When the full story comes out we will feature it on this blog. adds Dirk. This data presented in the distribution of tutoring subjects was taken from the last 5,000 tutoring requests (and not just from search data which is skewed due to spam and robot activity). As one might expect, the subject category of mathematics is the dominating category scoring 32% of all tutoring requests. Within this category algebra, calculus, statistics and geometry are the most frequent requested subjects. On place two of the subject categories are the English and science dead even at 17%. The most popular subject withing these categories are reading and chemistry, respectively. Although other sciences â€" physics and biology â€" follow close to chemistry in interest. Worth mentioning is a long tale in the sciences which includes somewhat more esoteric subjects like pharmacology, anatomy, genetics and neuroscience. On place three there are the language subjects (12%) out of which Spanish is the winner. It is followed by ESL (English as a second language), French and German. Reflecting the rising important of the largest U.S. trade partner, Chinese has become the 4th most often requested foreign language. The remaining subject categories are the test prep (GRE, ACT, SAT), music (piano, guitar) and computer subjects (JAVA, programming) as well as accounting and finance. The charts below illustrate our findings.

Should all exams be taken and submitted using computers - Tutor Hunt Blog

Should all exams be taken and submitted using computers Should all exams be taken and submitted using computers? Should all exams be taken and submitted using computers?Secondary SchoolsA friend of mine is a university examiner - she works for OCR (Oxford, Cambridge and RSA Exams). My understanding was that her job entailed compiling the papers: writing the questions, and making sure that the tests were comprehensively balanced. It turns out though that she has a far more onerous task: she has to mark the exams. `How hard can that be?` I thought to myself? She`ll obviously know what the answers are, she just has to read through each paper and grade it accordingly. I recall asking her if the most difficult part of her job was deciding just how many marks to award a student in a comprehension question, where there isn`t a clearly delineated right and wrong answer. `No, she answered, `The most difficult thing is trying to read students` awful handwriting!` It turns out this is the most common complaint from examiners - they have to decipher hundreds of pages of handwriting, with each student having their own idiosyncratic style of writing. My friend went on to tell me some of her concerns: `Some students have the most beautiful handwriting - while others have such a poor script it makes my eyes hurt! However bad their writing is, I`m obliged to decode it all. It`s not their penmanship that`s being tested - though sometimes the writing is so bad, almost completely illegible, I want to cross it all out and give them no marks at all!` `As the student nears the end of the exam, and time is running out, their writing becomes even worse, as they write faster and faster! I have to make sure i`ve read every line, however enigma-like it may be to decode, as it wouldn`t be fair to a student to gloss over words that might contain the correct answer.` Our current students may well be the last generation who sit examinations using paper and pen, for there are calls for all assessments to be undertaken using computers. There is really no reason why students can`t log into a web site that hosts the exam, and type out their answers, while sitting in a traditional examination hall. The examiner won`t even have to tell students to stop writing at the end of the examination, nor collect their papers once the assessment has concluded. There are many benefits to this method: the questions can be uploaded to the website on the day of the exam, negating the need for hundreds of confidential papers to be stored on school grounds days, or even weeks before the test. There won`t be any more cases of exam papers being stolen and distributed to students before the test, something that frequently happens according to my examiner friend; nor that of completed papers being lost prior to marking, something that also sadly occurs. Many people might balk at the idea of equipping students with computers during exams - while mobile phones are banned from the examination room, computers could be used with even greater facility to access the internet, allowing that elusive answer to be acquired. I suspect it wouldn`t be particularly difficult for schools to set up computers that are disabled in some manner, so they can`t access any Wi-Fi signal, so this is a concern that could likely be alleviated. There are some schools which have for some time mandated that students submit their answers on computers during exams, and I am not aware of any issues being raised. One concern that comes to mind however is that of questions that require an answer in the form of a picture or diagram. Certain questions in geometry or geography might rely upon a picture being submitted by the student, or a presented image being altered in some manner. I suspect this is not really a major problem though - computers are used by graphic artists every day, so it should be perfectly possible for the student to draw, for example, certain geometric shapes, or mark the border between two countries using a mouse. Exams submitted via computer could also provide some useful information to exam boards: they could track how long students take over each question, allowing them to assess the difficulty levels more accurately, helping them create new tests in the future. There will also be an environmental benefit in the reduction of paper use. Exams will be able to be graded faster, and more accurately, and my friend will be spared the punishment of having to decipher reams of spidery, hieroglyphic-like writing! 11 months ago0Add a Comment

The ALOHA program is designed to bring out children’s natural talent to learn and excel in school and later in life. Generations before the computer age schools taught traditional knowledge and concepts important to the industrial era. Why are collaboration, problem solving, critical thinking skills, and communication skills now important for students to learn and demonstrate regularly? The reasons are many. Obviously, these are skills adults use daily. Employers recognize the need as well, stating there is a shortage of employable applicants who already have these practical skills. ALOHA Mind Math helps solve the education and employability gap to give students between the ages of 5 years-old to 12 years-old an advantage over their peers. ALOHA CEO and President Mani Manickavelu says, “At ALOHA, our aim is not only have an impact on children’s academic performance, but to have an all-around effect that also results in improving confidence and achieving excellence.” ALOHA has helped thousands of children enhance their concentration, listening ability, and analytical skills, enabling them to comprehend and absorb more knowledge and concepts leading to excel on tests or participate in group projects within and outside the classroom. This also improves their reading, language arts, and mathematical aptitude. Creativity is welcomed. The student then develops confidence, becomes a problem solver, manages their emotions, works alongside their peers on class projects, communicates and handles decision-making appropriately, even in difficult situations. These are vital skills for their entire education and career success. It is Aloha Mind Math’s mission to go beyond reading, math, and language arts, and teach children crucial skills they need now which will carry with them throughout college and their entire life to lead happy and successful lives.
