A piece of metal A and a piece of metal B of the same mass and at the same temperature of 80°C are dropped into seperate beakers each containing 100.0 g of water at room temperature. Once they equilibrate, you find that the beaker with the sample of metal...

The reaction described takes place in solution in a coffe-cup style calorimeter. We will assume that the cups absorb or release a negligible amount of heat so we will not need to worry about the calorimeter constant or qcal. If the total mass of the solut...
