Use the following equations (picture) to determine the deltaH ° for the target reaction. Target: N2H2(l)+2H2O2(l)——> N2(g)+4H2O(l)

Given the following data: 2C6H6 (l)         +          15O2 (g)          →        12CO2 (g) + 6 H2O (l)            ΔG° =  –6399 kJ C (s)    + O2 (g)           →        CO2 (g)                                                                        ΔG° =  –394 kJ H2 (g)  + ½ O2 (g)       →        H2O(l)                                                                         ΔG° =  –273 kJ Calculate ΔG° for the reaction 6 C(s) + 3 H2(g)  ----> C6H6(l)                         ΔG° = ???
