For solutions are prepared and mixed together in the following order:
1. start with 100.0 mL of 0.100 M BaCl2
2. add 50.0 mL of 0.100 M of AgNO3
3. add 50.0 mL of 0.100 M H2SO4
4. add 250.0 mL of 0.100 M NH3
Write an equation for any reaction that occurs after each step and calculate the concentration of Ba^2+, Cl^-, NO3^-, NH3, and NH4^+, in the final solution, assuming that all reactions go to completion.
