q = mass x specific heat x delta T.
You have volume of water and density and that gives you mass H2O, specific heat you have and delta T you have. Calculate q.
Then q/0.689 = joules/g. Multiply that by atomic mass Ca to obtain J/mole and convert to kJ/mole.
When 0.689 g of Ca metal is added to 200.0 mL of 0.500 M HCl(aq), a temperature increase of 112C 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 Ca(s) + 2H+(aq) Ca2+(aq) + H2(g) is __________KJ/mol?
