I need to write equations that go along with this description
1) A white precipitate is formed when AgNO3 is added to HC2H3O2. When NH3 is added the precipitate it is dissolved.
and
2)
Add NaOH and aluminum powder to another portion of salt dissolved in water.
Add equal amounts of Iron (II) Sulfate to the portion of salt dissolved in water. Then ran Sulfuric Acid down the wall of the test tube.

When we added NaOH and aluminum powder , the result was the formation of NH3 gas. To confirm we saw the formation of a brown ring.
ok i got how to do the first one, but i dont get how to do the #2

The problem you are having isn't clear.... specify exactly what it is you don't understand.
BTW: AgNO3 is the 'salt' they are referring to.

The first reaction is a simple double exchange (metathesis) reaction.
Ammonia form complex with Ag+ cation. The Analogous reaction for AgCl you can find in most inorganic chemistry textbooks

]2)
Add NaOH and aluminum powder to another portion of salt dissolved in water.

This is a reduction reaction of NO₃^-

Add equal amounts of Iron (II) Sulfate to the portion of salt dissolved in water. Then ran Sulfuric Acid down the wall of the test tube.
