Net Ionic equation for

1. Iron(II) Iodide and Magnesium Acetate

2. Ammonium Phosphate and Cobalt(III) Chloride

3. Sodium Acetate and Potassium Chloride

These are the only ones I have left on my HW and I can't seem to figure them out would appreciate some help.

1 and 3 don't react so just the aq ions of those materials present. No ppts, no gases, etc.

2 forms CoPO4(s)
PO4^3- + Co^3+ ==> CoPO4
