When 0.633 g of Ca metal is added to 200.0 mL of 0.500 M HCl(aq), a temperature increase of 103C 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) ____kg/mol
I answered this question for Nicholas yessterday. His original post and my response is on page 4. If you can't find it, please repost and I'll try to redo it for you.
