The equation is balanced. There are 4 aluminium atoms and 6 oxygen atoms on each side.
The net ionic equation can be given as Sn²⁺ (aq) + S²⁻ (aq) → SnS (s).
<h3>What is an ionic equation?</h3>
The atoms or molecules on losing or gaining electrons in order to achieve the stable configuration results in the formation of positive or negative charge and are termed as ions.
The ionic equation can be given with the formation of the respective ions of the reactant and the product side.
SnSO₄ (aq) → Sn²⁺ (aq) + SO₄²⁻ (aq)
Na₂S (aq) → 2 Na⁺ (aq) + S²⁻ (aq)
SnS (s) → did not dissociates as form a solid covalent compound
Na₂SO₄ (aq) → 2 Na⁺ (aq) + SO₄²⁻ (aq)
The complete ionic equation can be given as:
Sn²⁺ (aq) + SO₄²⁻ (aq) + 2 Na⁺ (aq) + S²⁻ (aq) → SnS (s) 2 Na⁺ (aq) + SO₄²⁻ (aq)
Eliminating the common ions on the product and the reactant side:
Sn²⁺ (aq) + S²⁻ (aq) → SnS (s)

Answer: 1.91 moles
Explanation:
First you want to find the molar mass of NaCL
Na = 22.99g Cl = 35.45g
22.99g + 35.45g = 54.44g
Then divide 111.5g by 54.44g and this will give you moles.
Electron.......................
Answer:
Across a period, effective nuclear charge increases as electron shielding remains constant. A higher effective nuclear charge causes greater attractions to the electrons, pulling the electron cloud closer to the nucleus which results in a smaller atomic radius. ... This results in a larger atomic radius.
