You want to determine δh o for the reaction zn(s) + 2hcl(aq) → zncl2(aq) + h2(g) to do so, you first determine the heat capacity of a calorimeter using the following reaction, whose δh o is known: naoh(aq) + hcl(aq) → nacl(aq) + h2o(l) δh o = −57.32 kj(a) calculate the heat capacity of the calorimeter from these data: amounts used: 50.0 ml of 2.00 m hcl and 50.0 ml of 2.00 m naoh initial t of both solutions: 16.9°c maximum t recorded during reaction: 30.4°c density of resulting nacl solution: 1.04 g/ml c of 1.00 m nacl(aq): 3.93 j/g·kkj/°c(b) use the result from part (a) and the following data to determine δh o rxn for the reaction between zinc and hcl(aq): amounts used: 100.0 ml of 1.00 m hcl and 1.3078 g of zn initial t of hcl solution and zn: 16.8°c maximum t recorded during reaction: 20.5°c density of 1.0 m hcl solution: 1.015 g/ml c of resulting zncl2(aq): 3.95 j/g·kkj/mol
