QUESTION 1. When performing a calorimetry experiment, why is it desirable to use an insulated container with a lid?

(A) To prevent spillage when stirring
(B) To allow the thermometer to sit upright in the container
(C) To prevent energy losses to the atmosphere
(D) To allow for shaking when mixing the contents
(E) None of the Above

QUESTION 2. When performing an experiment to calculate the standard enthalpy of neutralization which of the following data are needed?

(A) The specific heat capacities of the solutions
(B) The masses of the solutions
(C) The initial temperatures of the solutions
(D) The final temperatures of the solutions
(E) All of the Above

QUESTION 3. Consider the following reaction profiles. Which statement is true for profile Z?

(A) The reaction is endothermic
(B) Products have a higher enthalpy than reactants
(C) Reactants have a lower enthalpy than products
(D) Delta H is positive
(E) None of the Above

QUESTION 4. Consider the following reaction profiles. Which statement is true for profile X?

(A) The reaction is endothermic since the products have a lower enthalpy than the reactants
(B) The reaction is endothermic since the products have a higher enthalpy than the reactants
(C) The reaction is exothermic since the products have a lower enthalpy than the reactants
(D) The reaction is exothermic since the products have a higher enthalpy than the reactants
(E) Delta H for the reaction is zero

QUESTION 5. Consider the following reaction profiles. In what way is profile Y the same as profile Z?

(A) Both are endothermic reactions
(B) Both have products with higher enthalpies than their reactants
(C) In both reactions, the enthalpies of the products are the same
(D) Both have positive Delta H values
(E) None of the Above
