IB Chemistry: Measuring energy changes questions

1. When 100 cm3 of 1.00 mol dm-3 sodium hydroxide, NaOH(aq), is added to 100 cm3 of 1.00 mol dm-3hydrochloric acid, HCl(aq), the temperature increases from 19.3 oC to 26.1 oC. Determine the enthalpy change of neutralization for the reaction.2. A student determined the enthalpy change for the reaction:CuSO4(aq) + Zn(s) → Cu(s) + ZnSO4(aq)She placed 50 cm3 of 0.140 mol dm-3 copper sulfate solution in a polystyrene cup...
