Al ions, CO32 ions =

Explanation / Answer

Part A

Na ion contains 1+ charge and CO3^2- so 2 Na^+ ions required to complete the formula.

So correct integer is

2,1

Part B

Ba contains +2 charge and CO3^2- contains -2 charge so 1 Ba^2+ required to complete the formula.

Correct integer is

1,1

Part C

Al contains +3 charge and CO3^2- contains 2- charge so 2 Al^3+ and 3 CO3^2- required to complete the formula.

So correct integer is

2,3
