8. (WCSU23, 9 pоints) The temperаture оf the cоpper аnd nitric аcid reaction rose from 22 °C to 32 °C. Determine the heat of reaction (ΔHrxn in kJ/mol Cu) when 3.8 g of Cu were used as the limiting reactant with 100 mL of HNO3 solution (d = 1.01 g/mL). The specific heat capacity of the solution is 4.184 J/g oC. (You may ignore any heat lost/gained by the calorimeter.)
