Question

Please any help would be much appreciated!!!

A pair of students performed an experiemnt to determine the heatof formation of zinc oxide. The reactions are entirely analogous tothe reactions of magnesium oxide. They reacted 1.504 g of zinc with100.20 g of 0.50 M hydrocholoric acid. (Zinc is the limitingreagent.) The initial temperature was 23.11 C and the finaltemperature was 31.36 C. If the heat capacity of zince chloridesolution formed in this reaction is 4.06 J ^-1 C^-1 and thecaloimeter constant is 7J C^-1, calculate enthalpy change for thequantity of zinc reacted. Be sure to follow the significant figuresconvention in the answer you report.
