Explanation:
<u>Step 1: Define</u>
Al₂(SO₃)₃ - Aluminum Sulfide
2Al₂(SO₃)₃
<u>Step 2: Identify</u>
In Aluminum Sulfide, we have 2 Al's for every 3 SO₃²⁻'s.
So far, we have 2 Al's in total.
BUT, since we have a 2 coefficient in 2Al₂(SO₃)₃, we need to multiply by 2.
Therefore, we have 4 Al's in total.

<h3>What is neutralization?</h3>
The term neutralization refers to the reaction between an acid and a base that yileds salt and water only.
The equation of this reaction is; 2HCl + CaCO3 ----->CaCl2 + CO2 + H2O
Number of moles of CaCO3 = 0.350 g/100 g = 0.0035 moles
Since 2 moles of acid reacts with 1 mole of CaCO3
x moles acid reacts with 0.0035 moles of CaCO3
x = 0.007 moles
Mass of acid = 0.007 moles * 36 g/mol = 0.252 g
