PLEASE HELP!! WILL AWARD BRAINLIEST!!!
Fill in the chart below (Table below) by writing formulas for the compounds that might form between the ions in the columns and rows. Some of these compounds don’t exist but you can still write formulas for them
P.S.(I tried)

| |Na+| |Ca2+| |Fe3+| |NH^+4| |Sn^4+|
|______|______|______|________|________
NO^−3___|____|______|________|________
SO2^−4___|____|_____|________|_________
Cl^−______|____|_____|________|________
S2^−______|____|_____|________|________
PO3^−4____|____|_____|________|_________
OH−_______|____|_____|_______|__________
Cr2O2^−7___|____|_____|_______|___________
CO2^−3_____|____|_____|_______|___________

Okay, I won't do every single one but i'll do a few so you can see how to work it out.

You want the charges to = 0 so that the compound is neutral.

Take Na+ and Cl-


This is a 1:1 ratio so you need 1 Na+ to balance the charges hence the equation is NaCl


For Na+ and CO2^3- the ratio is 1:3 so you need 3 Na


Na3CO2
