I am doing a project in Chemistry and I need to use Hess' Law to cancel two equations and if in one equation the NH4NO3 is solid and in the second one the NH4NO3 is aqueous.
The equations are:
1: NH4NO3 (s) + HCl (aq) --> HNO3 (aq) + NH4Cl (aq)
2: NH4OH (s) + HNO3 (aq) --> H2O (l) + NH4NO3 (aq)
I will find the heat of reaction for both of these reactions and use those values and Hess' law to find the Delta H of this reaction:
HCl (aq) + NH4OH (s) --> NH4Cl (aq) + H2O (l)I am wondering if these procedure will work because I created this myself for the project we are doing and I don't know:
1. Whether these individual reactions work
2. Whether they add up to the overall reaction and whether that reaction even works.
The part that is getting me stuck up is whether I can use Hess' law to cancel and aqueous version of NH4NO3 with a solid version.
Your knowledge and advice is much appreciated!
Thank you!
