assume you mix 100.0mL of .200M CsOH with 50.0mL of .400 M HCl in a coffee cup calorimeter the following reaction occursCsOH + HCl -> CsCl +H2O
the temperature of both solutions before mixing was 22.5C and it rises to 24.28C after the acid base reaction so what is the enthalpy change for the reaction per mole of CsOH? Assume the densities of the solutions are all 1.00g/mL and the specific heat capacities of the solutions are 54.2 J/gK
