The molar heat of solution of ammonia is −30.50 kJ/mol. What happens to the temperature of water when ammonia is added to it?

Question

I simply don't know how to answer this and wouldn't ask otherwise. I would be very grateful for assistance.

Answer 1

NH + H2O = NH3(aq) + 30.50 kJ/mol

So this tells you that the solution becomes warmer.
