What is the enthalpy of reaction, (triangle) H, for the formation of Tungsten carbide, WC, from the elements? W(s) + C(graphite) -> WC(s)

Use the following thermochemical equations:

2W(s) + 3O2(g) -> 2WO3(s); (triangle) H = -1685.8 kj

C(graphite) + O2(g) -> CO2(g); (triangle) H= -393.5 kj

2WC(s) + 5O2(g) -> 2WO3(s) + 2CO2(g); (triangle) H= -2391.8 kj
