When 1.045 g of cao is added to 50.0 ml of water at 25.0 °c in a calorimeter, the temperature of the water increases to 32.3 °c. assuming that the specific heat of the solution is 4.18 j/(g⋅°c) and that the calorimeter itself absorbs a negligible amount of heat, calculate δh in kilojoules/mol ca(oh)2 for the reaction

One of the hopes for solving the world's energy problem is to make use of the fusion reaction 21h +31h --> 42he + 10n + energy how much energy is released when 1 mol of deuterium is fused with 1 mol of tritium according to the above reaction? the masses of the atoms and the neutrons are as follows: 21h = 2.0140 amu 31h = 3.01605 amu 42he = 4.002603 amu 10n = 1.008665 amu. the speed of light is 2.9979 x 108 m/s.
