When 16.0 g of N2H4 and 184 g of N2O4 are mixed together and react according to the equation below, what is the maximum mass of H2O that can be produced? 2 N2H4 + N2O4 ---> 3 N2 + 4 H2O

How much heat transfer (in kj) is necessary to raise the temperature of a 0.250 kg piece of ice from −24.0°c to 128°c, including the energy needed for phase changes? (assume the substance remains at a constant volume throughout each stage of the heating process.)
