Chemistry

I I need so much help. Can anyone explain in detail what is going on?
The compound is Potassium Carbonate.
What would the flame color of potassium carbonate be?
What is the cation after the compound reacts with (NH4)2CO3, and (NH4)2SO4?
What is the anion after it has reacted with AgNO3, AgNO3 + HNO3, BaCl2, and BaCl2 + HCl?
I really don't know what I am doing so please if you could help me.

  1. Most of your question I don't understand. The flame color of K ion is a redish-violet color. I don't know that K2CO3 reacts with either (NH4)2SO4 or (NH4)2CO3. I don't know what the "anion" question means but K2CO34 will react with AgNO3 to form Ag2CO3 (white solid) which almost immediately turns a chocolate color of Ag2O. If HNO3 is added the Ag2CO3 dissolves forming AgNO3 along with H2O and CO2. gas. K2CO3 reacts with BaCl2 to form BaCO3 (white ppt) which will dissolve in HCl with the formation of CO2 gas and water. Hop;e this helps.
