When 0.756 g of Ca metal is added to 200.0 mL of 0.500 M HCl(aq), a temperature increase of 123C is observed.
Assume the solution's final volume is 200.0 mL, the density is 1.00 g/mL, and the heat capacity is 4.184 J/gC.
(Note: Pay attention to significant figures. Do not round until the final answer.)
The molar heat of reaction, H rxn , for the reaction of
