Please help me with AP Chem

Just answer me thinking that I don't know anything.

I have a few problems.

1. How do I know how many ions does a compound break into by just looking at the chemical formula of the compound?

2. If two compounds are mixed, how do I know which ions will combine and precipitate?

3. Most importantly, if the chemical formula is written in text, how do I know how many atoms of each element are present. For e.g. if Copper (II) Chloride is written, how do I figure out that it is CuCl?


Please help me.
