Question

Use the set of three reactions shown below to answer the questions that follow. 2NO(g) + O2(g) → 2NO2(g) ΔH = -116 kJ 2N2(g) + 5O2(g) + 2H2O(l) → 4HNO3(aq) ΔH = -256 kJ N2(g) + O2(g) → 2NO(g) ΔH = +183 kJ If 27.9 g of NO g is reacted with excess oxygen, how much heat energy is produced? What mass of liquid water will be consumed during the production of 33900 J of energy assuming that there is excess nitrogen and oxygen? Determine the heat of reaction in kJ for the reaction below. 3NO₂(g) + H₂O(l) → 2HNO₃(aq) + NO(g) ΔH = ?

4CO2(g) + 6H2O(l) → 2C2H6(g) + 7O2(g)	ΔH = 3120 kJ
2H2(g) + O2(g) → 2H2O(l)	ΔH = -572 kJ
4CO2(g) + 2H2O(l) → 2C2H2(g) + 5O2(g)	ΔH = 2600 kJ

Find the ΔH of the following reaction:

C2H2(g) + 2H2(g) → C2H6(g)
