Wow, what a bunch for you to ask!

We are not supposed to do your work. So, I'll give you some hints:

1. Acid + Metal carbonate -> Metal salt + Carbon dioxide + Water

2. All chlorides are soluble in water except silver and lead chlorides

3. All nitrates are soluble in water.

4. All sulfates are soluble in water except Calcium, Barium and Lead sulfates.

5. All lead salts are insoluble except lead nitrate. However, most dissolved upon heating and reappear upon cooling, except sulfate (to my knowledge)

6. Silver halides are generally insoluble. Silver chloride, bromide and iodide are insoluble in water, but soluble in aqueous ammonia. They are white, cream and yellow in colour respectively.

7. Halides are oxidants.

8. All carbonates are insoluble in water, except sodium, potassium and ammonium carbonates.

Post your answers, then we'll tell whether good or bad, what you have to do etc.
