Manganese reacts with hydrochloric acid to produce manganese(ii) chloride and hydrogen gas. mn(s)+2hcl(aq) ? mncl2(aq)+h2(g)
part a when 0.650g mn is combined with enough hydrochloric acid to make 100.0 ml of solution in a coffee-cup calorimeter, all of the mn reacts, raising the temperature of the solution from 23.0? c to 28.2? c. find ? hrxn for the reaction as written. (assume that the specific heat capacity of the solution is 4.18 j/g? c and the density is 1.00 g/ml.) express your answer using three significant figures. ? hrxn = kj
