Answer 2

A. Lose 4 electrons

Step-by-step explanation:

The reaction equation is given as:

S + NO₃ → SO₂ + NO

The half equation of the reaction for S:

S → SO₂

For S to go into SO₂,

we move from an oxidation state of 0 to +4,

Finding the oxidation state of S in SO₂

a + (-2 x 2) = 0

a - 4 = 0

a = 4

This is a loss of 4 electrons
