The Attempt at a Solution

For the first one, I'm thinking I should treat ammonia as a Group 1 metal and do a single replacement, but I'm not sure how this would work out.

For the second one, I have no clue how to start. Would the hydrogen pair up with the copper?

Thanks in advance for the help.

For the first you are right.
Same of the second you treat SO4 and NH3 group 1 and do a double replacement

This is b/c they are polyatomic ions

 

[Borek]

Wrong.

What is pH of ammonia solution?

What do you know of copper hydroxide solubility?

What do you know about ammonia copper complex?

What happens to ammonia in the solution of strong acids?

see when I looked at it, it just seemed to be a balancing sort of problem, like you get in grade school, just to teach you how to do it. Usually you ignore those sort of things for those problems.

But if it is more advanced then you should def look at what he said

When NH3 is mixed with CuSO4(aq), a double displacement reaction occurs. The ammonia acts as a base and reacts with the copper ions in the CuSO4 solution, forming a new compound called copper(II) hydroxide (Cu(OH)2) and ammonium sulfate (NH4)2SO4. The overall reaction can be represented as follows:

2NH3 + CuSO4 → Cu(OH)2 + (NH4)2SO4

When H2SO4(aq) is mixed with Cu(NH3)4+2, a similar double displacement reaction occurs. The sulfuric acid acts as an acid and reacts with the ammonia complex ion, forming a new compound called copper(II) sulfate (CuSO4) and ammonium sulfate (NH4)2SO4. The overall reaction can be represented as follows:

H2SO4 + Cu(NH3)4+2 → CuSO4 + (NH4)2SO4 + 2H2O

In both reactions, the products formed are a salt (Cu(OH)2 or CuSO4) and an ammonium salt (NH4)2SO4.
