When 0.667 g of Ca metal is added to 200.0 mL of 0.500 M HCl(aq), a temperature increase of 108C 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)

  • chemistry -

    And the question is?? Also, add the reaction arrow.

  • chemistry -

    the question is to find the molar heat of reaction of
    Ca(s) + 2H+(aq)= Ca2+(aq) + H2(g) (i don't know how to do the arrow so im just gonna use the = sign)
