methylhydrazine (ch6n2) is commonly used as a liquid rocket fuel. when 4.00 g of methylhydrazine is combusted in a bomb calorimeter, the temperature of the calorimeter increases from 25.00 oc to 39.05 oc. in a separate experiment the heat capacity of the calorimeter is measured to be 7.794 kj/oc. what is the heat of reaction for the combustion of a mole of ch6n2 in this calorimeter?
