1. Explain your answer

a) Which should have a more negative Hf benzene or fructose?

b) Which should have a lower (more negative) Hf, NaCl(s) or NaCl(aq)?

c) Reaction A B H = -3 kJ/mol. Reaction B C H = 5 kJ/mol. So Reaction A C H = ?

d) Reaction A 2B H = -3 kJ/mol. Reaction B C H = 5 kJ/mol. So Reaction A 2C H = ?

e) Reaction A B H = -3 kJ/mol. Reaction C B H = 5 kJ/mol. So Reaction A C H = ?

f) Hf of A = -3 kJ/mol. Hf of B = -5 kJ/mol. What is the H for reaction A B?

g) Hf of A = -3 kJ/mol. Hf of B = -5 kJ/mol. What is the H for reaction A 2B?

h) Hf of A = -3 kJ/mol. Hf of B = +5 kJ/mol. What is the H for reaction 5A 3B?
