Question

Accepted Answer

# Explanation:
## Step1: Combine Na⁺ and SO₄²⁻
To balance the charges, we need 2 Na⁺ for each SO₄²⁻. So the formula is Na₂SO₄.
## Step2: Combine Ba²⁺ and SO₄²⁻
The charges balance 1:1, so the formula is BaSO₄.
## Step3: Combine Mg²⁺ and SO₄²⁻
The charges balance 1:1, so the formula is MgSO₄.
## Step4: Combine Na⁺ and CrO₄²⁻
To balance the charges, we need 2 Na⁺ for each CrO₄²⁻. So the formula is Na₂CrO₄.
## Step5: Combine Ba²⁺ and CrO₄²⁻
The charges balance 1:1, so the formula is BaCrO₄.
## Step6: Combine Mg²⁺ and CrO₄²⁻
The charges balance 1:1, so the formula is MgCrO₄.
## Step7: Combine Na⁺ and NO₃⁻
The charges balance 1:1, so the formula is NaNO₃.
## Step8: Combine Ba²⁺ and NO₃⁻
To balance the charges, we need 2 NO₃⁻ for each Ba²⁺. So the formula is Ba(NO₃)₂.
## Step9: Combine Mg²⁺ and NO₃⁻
To balance the charges, we need 2 NO₃⁻ for each Mg²⁺. So the formula is Mg(NO₃)₂.
