Question 1

At 1.0133 bar, the heat of sublimation of gallium is 277 kJ mol-1 and the heat of vaporization is 271 kJ mol-1. To the correct number of significant figures, how much heat is required to melt 5.50 mol of gallium at 1.0133 bar?
◦ 33 kJ
◦ 6 kJ
◦ 244 kJ
◦ 274 kJ

Question 2

How much heat is absorbed/released when 40.00 g of NH3(g) reacts in the presence of excess O2(g) to produce NO(g) and H2O(l) according to the following chemical equation?

4NH3(g) + 5O2(g) → 4NO(g) + 6H2O(l)

Δ

rH° = 1168 kJ

◦ 685.8 kJ of heat are absorbed.
◦ 2743 kJ of heat are released.
◦ 2743 kJ of heat are absorbed.
◦ 685.8 kJ of heat are released.
