Mg reacts with H+ (aq) according to

\(\displaystyle{M}{g{{\left({s}\right)}}}+{2}{H}+{\left({a}{q}\right)}\to{M}{g}_{{2}}+{\left({a}{q}\right)}+{H}_{{2}}{\left({g}\right)}\)

Suppose that 0.524 g of Mg is reacted with 60.o ml of 1.0 M H+(aq). Assume that the density of the H+ (aq) solution os 1.00 g/ml,and that its specific heat capacity equals that of water. Theinitial and final temperatures are 22.0 degree celsius and 65.8degree celsius.

a) Is the reaction endothermic or exothermic?

b) Calculate \(\displaystyle\triangle{H}\) of of th reaction. Use correct sigs andgive units.

c) Calculate the \(\displaystyle\triangle{H}\) of the reaction per mole of magnesium.
