Heat of Formation for Ammonium chloride

  1. Oct 21, 2008 #1
    1. The problem statement, all variables and given/known data

    The problem statement is to find the heat of formation of NH4CL using the calculated variables and two more reactions.
    If I calculated it correctly the HF for ammonia plus hydrochloric acid to be -247.7kj/mol. I am not sure what else it is that I need to do.

    2. Relevant equations

    I am not sure how I am supposed to calculate delta H to begin with, I think that's where my problems are laying at the moment.

    3. The attempt at a solution
