Question

Which equation shows conservation of charge?(1) Fe → Fe²⁺ + e¯(2) Fe → Fe²⁺ + 2e¯(3) Fe + e¯ → Fe²⁺(4) Fe + 2e¯ → Fe²⁺

Answer 1

Conservation of charge is a principle of chemistry that states that the total electric charge of the system in an isolated system remains constant. It is conserved in the universe and does not varies.

For that reason, the equation that shows conservation of charge is:

Which is option 2.
