B. False. An alpha particle is a Helium nucleus which has a mass of 4 as it is made from 2 neutrons and protons each with mass of +1.
Answer:
The balanced half-reaction in which sulfate ion is reduced to sulfite ion is a two electron process
Explanation:
In the sulfate anion, S, acts with +6 in the oxidation number
SO₄⁻²
This is the anion from the sulfuric acid, when it lost the 2 protons
H₂SO₄ → 2H⁺ + SO₄⁻²
In the sulfite anion, S, acts with +4 in the oxidation number.
SO₃⁻²
This is the anion, generated when the sulfurose acid lost the 2 protons.
H₂SO₃ → SO₃⁻² + 2H⁺
In acidic medium
2H⁺ + SO₄⁻² + 2e⁻ → SO₃⁻² + H₂O
In basic medium
H₂O + SO₄⁻² + 2e⁻ → SO₃⁻² + 2OH⁻
