Question

I already figured out the first part of the problem, I just need help with b).

Chapter 6 1. a. Consider an aqueous reaction of equal volumes of 2.0 M HCI and 2.0 M NaOH, with a final volume of 100.0 mL and a density of 1.03 g/ml. What will the change in heat (qrxn) be for this reaction given a positive temperature change of 2.5 degrees Celsius? Assume a value of 4.18 J g' C-lfor Csoln. m=dxV = .039 l.039 x loomL=1o mL 1030(4.18) (て,5)C= l07し、355 -1076.355 -l,076KJ 7 b. Also calculate AHrxn for the acid.
