The following reaction occurs in a basic solution. Balance the reaction below. What is the coefficient in front of OH- in the balanced reaction?Ag(s) + Zn2+(aq) → Ag2O(aq) + Zn(s)124None, OH-is not in the balanced reaction.

The reaction given is: Ag(s) + Zn2+(aq) → Ag2O(aq) + Z

The reaction given is: Ag(s) + Zn2+(aq) → Ag2O(aq) + Zn(s)

First, we need to balance the reaction.

Step 1: Balance the atoms that appear in the most complex substances first. In this case, we start with Ag and Zn.

2Ag(s) + Zn2+(aq) → Ag2O(aq) + Zn(s)

Step 2: Balance the oxygen atoms by adding water molecules to the side that needs oxygen.

2Ag(s) + Zn2+(aq) → Ag2O(aq) + Zn(s) + H2O(l)

Step 3: Balance the hydrogen atoms by adding H+ ions to the side that needs hydrogen.

2Ag(s) + Zn2+(aq) + 2H+(aq) → Ag2O(aq) + Zn(s) + H2O(l)

Step 4: Balance the charge by adding electrons (e-) to the side that needs negative charge.

2Ag(s) + Zn2+(aq) + 2H+(aq) + 2e- → Ag2O(aq) + Zn(s) + H2O(l)

Step 5: Since the reaction is in basic solution, we need to neutralize the H+ ions by adding OH- ions to both sides.

2Ag(s) + Zn2+(aq) + 2H+(aq) + 2OH-(aq) + 2e- → Ag2O(aq) + Zn(s) + 2H2O(l) + 2e-

Step 6: Simplify the equation by canceling out the common terms on both sides.

2Ag(s) + Zn2+(aq) + 2OH-(aq) → Ag2O(aq) + Zn(s) + H2O(l)

So, the coefficient in front of OH- in the balanced reaction is 2.
