Answer to Question #67251 in General Chemistry for whitney

Question

During an experiment, a student adds 1.05 g of calcium metal to 200.0 mL of 0.75 M HCl. temperature increase of 17.0 °C for the solution.? 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, ΔHrxn.

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