CH4 + 4Cl2(g) CCl4(g) + 4HCl(g), DH = -434 kJ
Based on the above reaction, what energy change occurs when 1.2 moles of methane reacts?

Ok so based on the reaction, 1 mole of CH4 releases -434kJ of energy (the coefficient on CH4 would be 1, and therefore there is 1 mole of CH4 in that equation). Since you want to find out how much energy 1.2 moles would release, you have to use that information as a conversion factor. Start with 1.2 moles, multiply by .434kJ/1 mole. Moles will cancel out, and you'll be left with your answer in kJ.
