Note: reactiosn may not be abel to occur

1.Write the net ionic equation for any precipitation reaction that may be predicted when aqueous solutions of copper(II) iodide and barium hydroxide are combined. specify states such as (aq) or (s).

2.Write the net ionic equation for any precipitation reaction that may be predicted when aqueous solutions of calcium bromide and sodium sulfate are combined. specify states such as (aq) or (s).

3. Write the net ionic equation for any precipitation reaction that may be predicted when aqueous solutions of copper(II) sulfate and chromium(II) nitrate are combined. specify states such as (aq) or (s).
