5. How many kJ of energy are required to change 1.00 m^3 of purewater by 1.0*C? Assume a perfect system. The specific heat of thewater is 4.184 J/g*C. The density of water is 1.000 g/mL.
6. 2.500 grams of metal X (molar mass 65.39 g/mole) was reactedwith 100.0 mL of a 1.500 M HCl solution in a coffee cupcalorimeter. The temperature went from 12.50 *C to 40.50 *C.Determine the reaction enthalpy per mole of metal X. The specificheat of the solution is 4.184 J/ g*C. Assume a solution density of1.00 g/mL and a perfect system.
7. 20.12 grams of butane, C4H10, was combusted with oxygen in abomb calorimeter. The temperature of .500 kg of water went from5.00 *C to 25.89 *C. The specific heat of the water is 4.184 J/g*C.Assume a solution density of 1.00 g/mL. Determine the heat (kJ)evolved per mole of butane. Assume a perfect bomb calorimeter.
