CH4(g) + 2O2(g) --> CO2(g) + 2H2O(g) deltaH=-802.4 kJ/mol CH3OH(g) + 3/2O2(g) --> CO2(g) + 2H2O(g) deltaH=-676 kJ/mol You had left out the CO2 term in the first reaction so I added it...

• Science
The two given changes are carried out against a constant pressure. 1/2 N_2 (g) + 3/2 H_2 (g) ---> NH_3 (g) ---- (i) SiO_2 (s) + 3C (s) ---> SiC (s) + 2CO (g) ---- (ii) For the first change,...

• Science
The balanced chemical equation for the above reaction is: SO_2 (g) + 1/2 O_2 (g) = SO_3 (g) By definition, ΔH° = ΔHf°(products) – ΔHf°(reactants) = -396 – (-297 + ½ × 0) = -99...
