1. The equation is
DHrxn = (n*DHfproducts) - (n*DHfreactants)
Balanced the equation (I think it is balanced as is). DH stands for delta H and DHf is delta Hformation. You can find DHf information for 25C probably in the back of your text. Note: This method does NOT use the information in the problem; i.e., it does not use the heat of combustion.
