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
