Question

Calculate the heat of combustion of ethyne

Answer 1

Calculate the heat of combustion of ethyne, as described in the equationC2H2(g) + 2½O2(g) → 2CO2(g) + H2O(l), given the heats of formation of ethynegas, carbon dioxide gas and water liquid are +227 kJ mol-1, -393.5 kJ mol-1 and –285.8 kJ mol-1 respectively.
