Using values from Appendix C, calculate the value of ΔH° for each of the following reactions.
(a) 3 Fe(s) + 4 CO2(g) 4 CO(g) + Fe3O4(s)
ΔH° = kJ
(b) 4 NH3(g) + O2(g) 2 N2H4(g) + 2 H2O(l)
ΔH° = kJ
(c) 2 H2S(g) + 3 O2 (g) 2 SO2 (g) + 2 H2O(g)
ΔH° = kJ
(d) Fe2O3(s) + 6 HCl(g) 2 FeCl3(s) + 3 H2O(g)
ΔH° = kJ
I really don't know how to do this. Could you help explain it to me? I'm really bad at chemistry and would appreciate your help =D
