Homework Help: Stuck with Hess's Law

  1. Sep 29, 2008 #1
    1. The problem statement, all variables and given/known data
    Manipulate equations 1-3 to show the formation of the overall equation 4.
    Equation 4: HCl + NH3 --> NH4Cl

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



    3. 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...
