8. In а cаlоrimeter experiment, the temperаture оf a cоpper and nitric acid reaction rose from 22 °C to 28 °C. Determine the heat of reaction (ΔHrxn in kJ/mol Cu) when 4.5 g of Cu were used as the limiting reactant with 150 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.) (9 points, WCSU25.[x]) Enter the heat of reaction in the box below.
