Question

Iron reacts with hydriodic acid according to the balanced equation:
Fes)+2 HI(aq) FeCl,faq) + H(e)
When 0.402 g of Fe(s) is combined with enough Hl to make 75.0 mL of
solution in a coffee-cup calorimeter, all of the iron reacts, raising the
temperature of the solution from 23.5 C to 26.7 C. Find AHn for this
reaction as written. (Use 1.21 g/mL for the density of the solution and
4.18 J/g C as the specific heat capacity.)
