Explain an excess of zinc metal of a agno3 solution

Reference no: EM13668758

Explain an excess of zinc metal is added to 50.0mL of a 0.100 M AgNO3 solution in a constant-pressure calorimeter styrofoam cup. As a result of the reaction

Zn(s) + 2Ag+(aq) --> Zn2+(aq) + 2Ag(s)

The temperature increase from 19.25C to 22.17C. If the heat capacity of the calorimeter is 98.6J/C, Compute the enthalpy change for the above reaction on a molar basis. Presume that the density and specific heat of the solution are the same as those for water, as well as ignore the specific heats of the metals
