Kinetics of Hydrogen Peroxide February 22‚ 2007 Chem. 1130 TA: Ms. Babcock Room 1830 Chemistry Annex PURPOSE OF THE EXPERIMENT Kinetics of Hydrogen Peroxide The major purpose of this experiment is to determine the rate law constant for the reaction of hydrogen peroxide and potassium iodide. In this experiment‚ the goal will be to try to measure the rate law constant at low acidity‚ since at low acidity‚ anything less than 1.0 x 10-3M‚ the effect of the hydrogen ion is negligible. To calculate

SCH4U 03/04/13 Hydrogen Bonding Purpose: The purpose of this investigation is to test the concept of hydrogen bonding. Hypothesis: Given the concept of hydrogen bonding I predict that the bulky glycerol molecules limits the number of possible hydrogen bonds. If water is mixed with glycerol should make it possible for water to form many hydrogen bonds with the glycerol molecules‚ causing it to become a exothermic reaction. Because glycerol has more possibilities for hydrogen bonding I believe

bombs and hydrogen bombs. The hydrogen bomb is the most powerful‚ destructive bomb of all. In this essay I’m going to give a brief history of the hydrogen bomb‚ the chemistry behind the bomb‚ and how much destruction the hydrogen bomb can do. After the Soviet Union’s atomic bomb success during the cold war‚ the U.S wanted something bigger and stronger. In 1950‚ President Harry S. Truman announced work on the hydrogen bomb. A group of scientists led by Edward Teller created the first hydrogen bomb in

Aims The aims of this investigation are: 1. To find the rate equation of the reaction of hydrogen peroxide and iodide ions. This will be achieved by using an iodine clock method and colorimetric analysis. 2. Draw a graph of rate against concentration for each reactant (Hydrogen peroxide‚ potassium iodide and H+ ions). 3. Finding the order for each reactant 4. Finding the rate-determining step. 5. Proposing a mechanism for the reaction. 6. Using Arrhenius’ equation to find the activation

result from the exchange of positive and negative ions between reacting solutions of two ionic compounds. Thus‚ in this example the precipitate must be either silver chloride‚ AgCl or sodium nitrate‚ NaNO3. Sodium nitrate dissolves readily in water and is therefore soluble. Thus we can conclude that silver chloride is the insoluble precipitate. We can represent the formation of this precipitate by a net ionic equation: Ag+ +NO3 ̄ +Na++Cl ̄→AgCl+NO3 ̄+Na+ Net: Ag+ (aq)+Cl ̄ (aq)→AgCl(s) Ions present

ADD AND ADHD Causes‚ and Symptoms Health experts say that ADHD attention deficit hyperactivity disorder is the most common behavioral disorder that starts during childhood. However‚ it does not only affect children it can also affect people of all ages this people can suffer from ADHD. According to psychiatrists they say ADHD is a neurobehavioral developmental disorder. An individual with ADHD or ADD finds it much more difficult to focus on something without being distracted. He or she is
