Zinc metal reacts with hydrochloric acid according to the following balanced equation.
zn(s)+2hcl(aq)→zncl2(aq)+h2(g)
when 0.121 g of zn(s) is combined with enough hcl to make 52.5 ml of solution in a coffee-cup calorimeter, all of the zinc reacts, raising the temperature of the solution from 21.8 ∘c to 23.9 ∘c. find the enthalpy change (in kj/mol) for this reaction as written. (use 1.0g/ml for the density of the solution and 4.18 j/g *celcius as the specific heat capacity.)
