During an experiment, a student adds 1.05 g of calcium metal to 200.0 mL of 0.75 M HCl. The student observes a temperature increase of 17.0 °C for the solution. Assuming the solution\'s final volume is 200.0 mL, the density is 1.00 g/mL, and the specific heat is 4.184 J/(g·°C), calculate the heat of the reaction, Hrxn.

Ca(s) + 2H^+(aq) >> Ca^2+(aq) + H2(g)

Hrxn = ___ kJ/mol
