During an experiment, a student adds 0.339 g of calcium metal to 100.0 mL of 2.05 M HCl. The student observes a temperature increase of 11.0 °C for the solution. Assuming the solution\'s final volume is 100.0 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) ---> Ca2+ (aq) + H2(g)
