Compound A undergoes a reaction with B to produce C gas and liquid D. The standard heat of combustion of compound A is -1,624.2 kJ/mol. Given that ΔH°f[B(g)] = -155.0 kJ/molΔH°f[C(g)] = -417.4 kJ/mol, ΔH°f[C(g)] = -417.4 kJ/mol, and ΔH°f[D(l)] = -230.8 kJ/mol,
what is the standard enthalpy of formation of Compound A?
A + 3 B(g) --> 2 C(g) +3 D(l)
