t Question 5 074 pts Given the balanced chemical equation: Fe(s) + 2 HCl(aq) - FeCl2lag) + H2(8) AHrxn ?? A sample of 0.73 g of Fe metal is combined with excess HCl to make 200 g of solution in a calorimeter and allowed to react completely. If the temperature of the solution rises from 25.0 C to 29.6 C, find AHrxn in kJ for this reaction. (Cs of soln = 4.184 J/g C) (1 kJ-1000) soin Arxn Csoin moim, AT 4 = mxc X AT AH AH 9rx = -9 soln Arxn mol of Fe Don't forget to include the signs.
