Calculate the enthalpy (ΔH) for each reaction. __C(s) + __Fe2O3(s) --> __3CO(g) + __2Fe(s) ΔH = ___kJ/mol

2) 3Mn(s) + Fe2O3(s) --> 3MnO(s) + 2Fe(s) ΔH = ___ kJ/mol

3) 12P(s) + 10Fe2O3(s) _--> 3P4O10(s) + 20Fe(s) ΔH = ___kJ/mol

4) 3Si(s) + 2Fe2O3(s) --> 3SiO2(s) + 4Fe(s) ΔH =___ kJ/mol

5) 3S(s) + 2Fe2O3(s) --> 3SO2(g) + 4Fe(s) ΔH = ___ kJ/mol
