Axle · Answer 1

1. Balanced

2. Unbalanced

3. Unbalanced

Explanation:

Identify which of the following oxidation-reduction reactions are balanced and which are unbalanced in both mass and charge.

1. Ag⁺ (aq) + Li (s) → Ag (s) + Li⁺ (aq)

This reaction is balanced in both mass and charge.

2. Fe (s) + Na⁺ (aq) → Fe²⁺ (aq) + Na (s)

This reaction is balanced in mass but unbalanced in charge since the charge to the left is + 1 and the charge to the right is 2+.

3. K (s) + H₂O (l) → KOH (aq) + H₂ (g)

This reaction is balanced in charge but unbalanced in mass since there are 2 atoms of H to the left and 3 atoms of H to the right.
