Explanation:

Step1: Identify cation and anion for Al(NO₃)₃

Aluminum (Al³⁺) is the cation and nitrate (NO₃⁻) is the anion.

Step2: Name the compound

The name is aluminum nitrate.

Step3: Identify cation and anion for Fe₂(SO₄)₃

Iron (Fe³⁺) is the cation and sulfate (SO₄²⁻) is the anion. Since iron has multiple oxidation states, we use the Roman - numeral (III) to indicate its charge.

Step4: Name the compound

The name is iron(III) sulfate.

Step5: Determine formula for barium oxide

Barium (Ba²⁺) and oxygen (O²⁻) combine in a 1:1 ratio to balance charges.

Step6: Write the formula

The formula is BaO.

Answer:

Aluminum nitrate
Iron(III) sulfate
BaO
