Chemistry Half Life Equation - Use It

Chemistry Half Life Equation - Use ItStudents will often wonder about the half-life equation in the college chemistry class. This equation gives an easy calculation of how long it will take to clean a dilute sample of the chemical which is in a sample. It's actually easy to find.You may also have noticed that there are two sides to every complex system. You can choose to think of them as positive and negative sides. In this case, you can see the equation from the perspective of the positive side and the negative side. So if you have a sample of water and it has dissolved potassium chloride, it will have a half life of four days.That means that the potassium chloride has taken four days to mix with the sample. However, this half life does not include the time required for the reaction to occur. Thus the half life does not have to include the time taken for the reaction to occur.Let's say that you are studying about a complex system that has a reactant and an electron donating an elect ron, and it has a complicated mechanism. The chemical reaction is complex enough, and if you are studying something like this, you can study using simple decimal notation. If you have the equation for the complex system and you have the time to write the equation out, you can easily get the answer by subtracting one from the other.In this case, you would add the half life to the equation of potassium chloride. That gives you an equation that is nearly quadratic in degree, and so the equation of potassium chloride has a half life of five days. If you have the rest of the information about the system, you can find out the precise half life of the system.In your chemistry class, the course is really quite good about having the half-life equation available. Some of the chemistry classes even encourage students to use the equation as a way to solve their own problems. The half-life equation is actually quite useful to students, but it is not always easy to remember and use it.The next ti me you want to work on a problem, especially one that requires you to do some calculations, do not forget to use the equation for your chemistry work. It is that easy!

What can you do to help your child cope with stress - ALOHA Mind Math

What can you do to help your child cope with stress A fifth grade teacher at Roosevelt Elementary School in Janesville, Michael Smrekar talks in this articleabout how expectations on today’s kids have become much higher than even a few years ago. He says today’s fifth graders are learning even pre-algebra skills which is a lot more than the parents of today’s kids did when they were young. Not just math, but even where reading levels are concerned, children are expected to read earlier and better than their predecessors. Image courtesy : www.flickr.com/photos/saranv/35212873881 What can a parent do in this scenario? Here are some ways in which we can help our children cope with the stress, as well as understand it a bit better ourselves: Communicate: This is the base skill most important for all parents. Try your best to set aside a part of each day, when you just “talk” to your child. From the happenings in school, and among friends, you will learn a lot of what goes on in your child’s day. As time goes on, if she feels that there is always a non-judgmental time she can share with you, you can hope that she’ll open up about anything that bothers her. Keep track: Have regular discussions with your child and occasionally with his teacher if possible, so that you have an accurate idea of what is happening at school. This way, you can try to approach difficult subjects in advance to make your child more comfortable with them. Get rid of preconceived expectations: In the same vein, do not form an opinion based on a report from school. Discuss with your child to understand what exactly the problem might be, and why he might not be doing well in a particular subject. This is the best approach to decide on whether extra coaching may be necessary, or even in a few cases to diagnose a learning disability. Parents are the best observers of their children, and can make a decision accordingly. Extra-curricular activities: Set aside some time each week for an activity that would help your child to blow off some stress. Remember that this should not be just something that you would like her to learn, but something she loves as well. In this context, if you can find some games for children that emphasizes fun over competition, that would be the best option. With these small tips, you can do your bit towards enabling your children in a high-pressure environment, and to help them perform to their best abilities. Our Math and English classes at Aloha are tailored to coincide with the learning content at school, to help your child gain confidenc e in all subjects.

Punctuation Saves Lives

Punctuation Saves Lives Punctuation saves lives! What? How come? Yes. Here is the example: Lets eat kitty. (Meaning that, we will be eating a cat.) Lets eat, kitty. (Meaning that, you and your friend kitty will be starting to eat.) The above example is a punctuation rule. Your tutor would put it formally like this: Use commas to set off the name, nickname, or title of a person you have directly addressed. More Examples: Yes, old friend, I will. Good day, Captain.

Five Signs Your Child Needs a Tutor

Five Signs Your Child Needs a Tutor Between demanding studies, extracurricular activities, and busy family lives, individual attention can help students of all ages and abilities. Perhaps you've found yourself wondering how to give your child a more enjoyable academic experience. These five signs can help you determine whether it's time to HIRE A TUTOR. 1. Low Test Scores Whether you've noticed a slip in your child's grades or simply believe he/she can do better, a tutor can offer valuable partnership in getting your child back on track. The right tutor can offer insights into your child's strengths and identify any areas of weakness. A tutor will proactively work with your child to help him/her master problematic areas. 2. Confidence Issues Low self-esteem can affect your child's report card. Changes in a child's self-esteem are often caused by struggles in school. Unfortunately, this can have a domino effect, leading to anxiety about tests, homework, and attendance. A tutor can immediately identify skill gaps and work with your child to correct them. A wonderful side benefit is a boost in your child's self-esteem that will carry over into all areas of life. 3. Trouble with Time Management Procrastination is normal, but if your child is constantly avoiding assignments, it may indicate that he/she is stuck or cannot handle the workload. A tutor can work with your child to teach positive study habits, learn the material, and instill a sense of self-motivation. 4. Life Changes A new job, the birth of a baby, or a recent move may prevent you from offering your child the same level of help as before. In addition, you may notice that homework load increases as your child advances from grade to grade. If you're unable to fit homework help into your schedule, a tutor can act as an invaluable backup. The largest study ever on parental involvement in children's lives indicated that parents can actually have a negative impact on homework grades. For this reason, consider hiring a trained tutor instead of trying to help with topics you're unfamiliar with. 5. Learning Disability Diagnosis If your child has been diagnosed with a learning disability, you may be trying to understand how it affects him/her academically. Many tutors are trained in teaching children with learning disabilities. They can offer specialised sessions aimed at helping kids establish healthy study habits and learn in the manner that suits them best. One last sign that your child may need a tutor is your own intuition. If you feel like your child may be struggling at school, quick, corrective action is in order. PRIVATE TUTORS not only ensure that kids' needs are being met, but that their academic experience remains positive, too.

13 Reasons Why Resources for Teachers

13 Reasons Why Resources for Teachers Chances are, if you’re a teacher, you’ve already have heard about (or watched) the Netflix series 13 Reasons Why, released early last month. Based on a popular young adult novel, 13 Reasons Why follows the story of a teenage girl who commits suicide, leaving behind a series of tapes for various people explaining why they’re responsible for her death. Recently, the series has been embroiled in controversy. School psychologists and suicide prevention experts have almost universally criticized the show, arguing that it sends the wrong message about teen suicide. Suicide is among the leading causes of death for young people and teachers play an important role in keeping their students safe. As a key setting for suicide prevention, schools have been sending out warnings and issuing talking points about the show. The National Association of School Psychologists (NASP) is advising teachers not to discuss the show unless their students are already talking about it. So, while the show shouldn’t be used as a teaching tool, there's no doubt that it’s being widely watched by adolescents and school leaders and educators alike have a responsibility to promote suicide awareness. Below, we’ve collected a quick round-up of some helpful resources to help educators learn more about youth suicide prevention: The NASP has released guidelines on 13 Reasons Why for parents and educators. For additional guidance, also check out their resource on Preventing Youth Suicide: Tips for Parents and Educators and Preventing Youth Suicide: Brief Facts. Suicide Awareness Voices of Education (SAVE) and the JED Foundation have created talking points for teachers who want to discuss 13 Reasons Why with their students.

Slope of a Vertical line

Slope of a Vertical line A vertical line is the line that is parallel to the y axis as, the y-axis is the vertical line. The equation of the y axis is x = 0. Slope of a line is defined as raise over run. The slope of a straight line is calculated by the change in the y co-ordinates divided by the change in the x co-ordinates of any two points on the straight line. Example 1: Find the equation of the straight line parallel to y axis and passing through the point (3, 4)? Solution: Given, the line is parallel to the y axis. The equation of the y axis is x = 0. The lines are parallel so they have the same slope. The slope of the y-axis is undefined. Hence the slope of the vertical line is undefined. General form of the vertical line passing through (a, b) is x =a The line is passing through (3, 4). Therefore the equation of the vertical line is x = 3. Example 2: Find the equation of the straight line parallel to y axis and passing through the point (1, -5)? Solution: Given, the line is parallel to the y axis. The equation of the y axis is x = 0. The slope of the y-axis is undefined. Hence the slope of the vertical line is undefined. General form of the vertical line passing through (a, b) is x =a The line is passing through (1, -5). Therefore the equation of the vertical line is x = 1.

Solving Linear Equations With Fractions

Solving Linear Equations With Fractions There are many kinds of equations in algebra. Linear equations are the equations where the degree of the variable can be only one.There can be one or more than one variable in a linear equation. A linear equation also consist of coefficients and constants. The numbers can be many numbers in a linear equations including fractions. A fraction is a number which is written in p/q form. Here p,q are integers and the condition is q cannot be equal to zero. Different mathematical operations can be used to simplify and solve a given fraction like addition, subtraction, multiplication and division. Example 1: Solve the linear equation 5x 7/2 = 3/2? Solution: Given equation is 5x 7/2 = 3/2. Here the unknown variable which needs to be solved for is x. Step 1: Add 7/2 on both sides of the equation. This gives 5x 7/2 + 7/2 = 3/2 + 7/2; 5x = (3+7)/2; 5x = 10/2. Divide both sides of the equation by 5; 5x/5 = 10/10 Hence the solution is x = 1. Example 2: Solve the linear equation 7x 10/3 = 4/3? Solution: Given equation is 7x 10/3 = 4/3. Here the unknown variable which needs to be solved for is x. Step 1: Add 10/3 on both sides of the equation. This gives 7x 10/3 + 10/3 = 4/3 + 10/3; 7x = (14)/3; 7x = 14/3. Divide both sides of the equation by 7; 7x/7 = 14/21. Hence the solution is x = 2/3.
