Writing formulas help please!

Write the formulas of the compounds produced from the listed ions.

Na+ and Cl-
Na+ and CO3 ^-2
Na+ and OH-
Na+ and SO4 ^-2
Na+ and PO4 ^-3
Na+ and NO3 -

The key to making formulas is the "drop and swap." So let's say for example Mg 2+ and N 3-. So if you can, visualize dropping the charging into a subscript, and then swapping the two numbers. So then the formula then becomes Mg3N2.

Na+ and Cl- = NaCl

Na+ and CO3 ^-2 = Na2CO3

Na+ and OH- = NaOH

Na+ and SO4 ^-2 = Na2SO4

Na+ and PO4 ^-3 = Na3PO4

Na+ and NO3 - = NaNO3
