From the following data, C (graphite) + O 2(g)  –> CO 2(g)…

From the following data, C (graphite) + O 2(g)  –> CO 2(g) = -393.5 kJ/mol H 2(g) + 1/2O 2(g) –> H 2O (l) = -285.8 kJ/mol 2C 2H 6(g) + 7O 2(g) –> 4CO 2(g) + 6H 2O (l) = -3119.6 kJ/mol calculate the enthalpy change for the reaction 2C (graphite) + 3H 2(g) –> C 2H 6(g)
