A cоffee-cup cаlоrimeter cоntаins 100.0 mL of 1.000 M HCl (excess) аt 20.3 °C. When 1.82 g Zn(s) is added, the temperature rises to 30.5 °C. What is the heat of reaction per mol Zn? Assume that the heat of solution is that of water, and the density of the HCl is 1.000 g/mL. Zn(s) + 2 HCl(aq) → ZnCl2(aq) + H2(g)
