NaOH Standardization and Titration of an Unknown Organic Acid Overview: Methods for counting the number of molecules in a sample is a major emphasis of laboratory work. In this experiment we will use the method of titration to count the number of acid molecules in a solution. Measuring mass is a relatively easy procedure to do in the lab (although a balance is expensive). Counting the number of particles requires more effort. Molecular counting can be done by setting an unknown amount of a substance

Introduction Obesity can lead to various health problems. My school has decided to carry out a “Healthy Lifestyle Campaign” with the aim to create awareness among students about obesity-related health problems. The Body Mass Index (BMI) gives an indication of the physical state of person as being underweight‚ normal‚ overweight or obese. BMI can be calculated by using the following formula: BMI = History Body Mass Index (BMI) The body mass index (BMI)‚ or Quetelet index

ADD/ADHD Research ADHD and ADD ADHD is real in the view of many scientific researchers and families. Attention Deficit/Hyperactivity Disorder (ADD/ADHD) is the most commonly reported childhood behavioral disorder‚ affecting between 3 and 7% of American children. It is characterized by poor attention span‚ impulsive behaviors‚ and hyperactivity in some children. The diagnostic criteria are strictly observational‚ and there are no objective laboratory tests to confirm that diagnosis. Subjective

In essence‚ the goal is to find the data with only one search. The hash search runs very quickly because of this. It’s Big O‚ or orders of power‚ approaches O(1) and will never exceed O(n). To accomplish this search‚ a program is written in which the key is passed into the hash function‚ which in turn‚ finds the address of the data needed. To
