Chemical energy is released or absorbed from reactions in various forms. The most easily measurable form of energy comes in the form of heat, or enthalpy. The enthalpy of a reaction can be calculated from the heats of formation of the substances involved in the reaction: Delta H_rxn degree = Delta H_f degree (products) - Delta H_f degree (reactants) Calculate the standard enthalpy change for the reaction 2A + B 2C + 2D Use the following data: For the reaction given in Part A, how much heat is absorbed when 3.80 mol of A reacts? Express your answer numerically in kilojoules.
