Question 1

How much heat is absorbed when 50.00 g of C(s) reacts in the presence of excess SO2(g) to produce CS2(l) and CO(g) according to the following chemical equation?

5C(s) + 2SO2(g) → CS2(l) + 4CO(g)

Δ

rH° = 239.9 kJ

◦ 998.3 kJ mol-1
◦ 199.7 kJ mol-1
◦ 239.9 kJ mol-1
◦ 2398 kJ mol-1

Question 2

At constant pressure, the combustion of 20.0 g of C2H6(g) releases 1036 kJ of heat. What is ΔH for the reaction given below?

2C2H6(g) + 7O2(g) → 4CO2(g) + 6H2O(l)

◦ -1560 kJ mol-1
◦ -173 kJ mol-1
◦ -3120 kJ mol-1
◦ -779 kJ mol-1
