Unformatted text preview: water. NH 4 NO 3 NH 4 + +NO 3-We found the molar heat of the solution to be 12031.2(kj/n), compared to the calculated 28600. This error is due to incorrect temperatures. The temperatures caused our molar heat to be less than half of what it should be. Had our temperatures had a difference of two or three more degrees, our molar heat would have been more accurate. I think our temperatures were off because we didnt put the thermometer into the calorimeter quickly enough after adding the ammonium nitrate. In part IV we found the heat of a neutralization reaction. We mixed HCl with NaOH. HCl+NaOHNa + +Cl-+H 2 O We found the heat capacity of the neutralization to be -56956.2kj/n compared to the actual -55830kj/n. The discrepancy is because of the change in temperature being too high, most likely because the initial temperatures we recorded as lower than they actually were....
