Homework Statement


Manipulate equations 1-3 to show the formation of the overall equation 4.
Equation 4: HCl + NH3 --> NH4Cl

Homework Equations


1. NaOH + HCl --> NaCl + H2O
2. CH3CO2H + NaOH --> CH3CO2- +Na+ + H2O
3. CH3CO2H + NH3 --> CH3CO2- +NH4+



The Attempt at a Solution


I kept equation 1 and 3 the same, reversed equation 2 and summed them. My result is HCl + Na + NH3 --> NaCl +NH4.

I have no idea how to get to equation 4 from here...
