Question

Which of the following statements apply to the general experimental procedure for determining the heat of reaction as described in the experiment reading? One or more may be correct and you will receive negative points for incorrect answers.
A. Measurements of the temperature of the solution in the calorimeter should be taken at regular intervals for several minutes before the reactant is added.
B. The solution in the calorimeter should not be stired during the experiment because stirring wil slow the reaction
C. The solution calorimeter does not need to be rinsed or dried between runs because the reaction solutions are all aqueous.
D. Temperature readings need to be taken at regular intervals after the highest temperature reading is observed to determine the rate of heat loss from the calorimeter.
