Question

The Standard reactions Enthalpie from the following reactions are:

1) C + O2 = CO2. deltaH298 = -393.8 Kj/mol

2) H2 + 0.5 O2 = H2O deltaH298 = -286,2 Kj/mol

3) C6H6 + 7.5O2 = 6CO2 + 2H2O deltaH298 = -3267,7 Kj/mol

How big is delta H298 for the following reaction: ?? C + ?? H2 = ?? C6H6

Help is really appreciated! Thanks!
