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

Example problems involving collisions 1) On a horizontal frictionless surface a puck of mass m initially at speed u collides head-on (without rotation) with a stationary puck of mass M. Find the velocities of both puck after the collision if: i) the collision is fully elastic ii) the collision if fully inelastic. i) momentum: kinetic energy: mu = mv+MV (+ve in direction of initial u) 1 /2 m u2 = 1/2 m v2 + 1/2 M V2 2 eqns in 2 unknowns: V = (u - v) m/M substitute in K eqn: u2 = v2 + (M/m) V2 =

conducted to find the specific heat of a metal as well as the heat of solution of a solid. Both experiments required the use of calorimetry to measure heat flow and temperature change. The specific heat of the metal was found by heating it in boiling water before transferring it to the calorimeter that was partially filled with water. After shaking the calorimeter‚ the temperature change was measured and recorded. This information was used to calculate the specific heat. The heat of solution of a solid

seek out answers rather than avoid problems. It is effective questioning‚ where one does not merely take facts at face value but rather puts effort into checking and testing those claims‚ which in turn helps him better reflect upon the world around him. Personally‚ the process on Inquiry has‚ and will continue to help me immensely throughout my academic career‚ through how it affects me personally‚ how it relates to Liberty University‚ and in the future as I continue to participate in the larger

As suggested‚ we performed the enzymatic experiments as described in material and methods. It was observed that CgAKR-1 has activity on acetaldehyde‚ corresponding to 59.2 % of the activity with the standard substrate 2-nitrobenzadehyde. Moreover‚ the enzyme had no activity against acetone (Propanone); the result was included in Table 1. According to Santoro et al. [76]‚ it was not detected acetaldehyde in hemicellulosic hydrolysate‚ which was produced at the same conditions described in the present

1. What is a deductible? How does a deductible affect insurance? C A deductible is the amount of money that the policyholder will pay before the insurance company will pay on the insured loss. A deductible affects insurance because you are responsible for paying a certain amount before the insurance company will pay the rest of the insured amount to fix what ever you need fixed. 2. What is risk classification? C A risk classification is the assessment and categorization of the characteristics that
