Question: Consider the following chemical reactions: 1. 2H(g) + O(g) 2HO(g) AH = -572 kJ/mol 2. C(graphite) + O(g) CO(g) AH = -394 kJ/mol 3. 2H(g) + C(graphite) CH4(g) AH3 = -75 kJ/mol Using Hess's Law, calculate the enthalpy change (AH) for the reaction: CH(g) +20(g) CO(g) + 2HO(g) Question: Consider the following chemical reactions: 1. 2H(g) + O(g) 2HO(g) AH = -572 kJ/mol 2.
