Identify which of the following oxidation-reduction reactions are balanced and which are unbalanced in both mass and charge. 1.2.3.ag+(aq)+li(s)fe(s)+na+(aq)k(s )+h2o(l)→→→ag(s)+li+(aq)fe2+(aq)+na (s)koh(aq)+h2(g) drag the appropriate items to their

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.

thats a little if u want the answer just look it up on google thats what i do haha : )
