Homework Help: Chemistry-Thermochemistry (grade 12)

Posted by Rose Bud on Thursday, February 16, 2012 at 1:06am.

A 65.0 g sample of 0.600 M HI at 18.46 degrees celsius is added to 84.0 g of solution containing excess KOH, also at 18.46 degrees celsius. The final temperature is 21.96 degrees celsius. Calculate the enthalpy of H for the reaction.

Assume the specific heat of the solution is 4.184 J/g(degrees celsius), and the calorimeter has negligible heat capacity .

HI(aq) + KOH(aq) --> KI(aq) + H2O(l)

enthalpy of H ?
