How can I use the heat of combustion to calculate the reaction enthalpy?

You can solve this problem by just adding the s correctly. In this problem all you would need to do is change -1560kJ to +1560kJ because is the product in this reaction. You also need to multiply -286kJ by 2 because there are two moles of . The -1300kJ of does not need to be altered because it just moves down. Then you just add all the new s you computed to get your answer.
