Alright, so to do this, you need to know the name of the elements and compounds, since all of these are ionic compounds which have different naming rules than covalent compounds, all you need is a periodic table and an ion chart. I'll do the first column.
A. Calcium Nitrate
B. Potassium Hydroxide
C. Magnesium Carbonate.
I also am including a picture of an ion chart that include almost all of the ions to help you with the rest of them.
