Reaction 1: NaOH(s)--> NaOH (aq)

Reaction 2: NaOH(s) + HCl (aq)--> NaCl(aq)+H2O(l)

Reaction 3: NaOH(aq) +HCl (aq) --> NaCl (aq) + H2O (L)

1) Describe each reaction as endothermic or exothermic and explain your reasoning.

2) Examine the chemical equations for the three reactions. Determine their relationship in a way that is consistent with Hess's Law. (i.e. verify that Hess's Law is upheld. Reaction 3 is the target equation).

3) Why is heat a stoichiometric quality?

4) Just what IS a heat of solution?
