Expert Answer

Step 1

Since we only answer up to 3 sub-parts, we’ll answer the first 3. Please resubmit the question and specify the other subparts (up to 3) you’d like answered.

Step 2

Part (1)

In electrochemical series silver (Ag) is above than iron (Fe). Therefore, silver has more tendency to get reduced and therefore oxidizes iron (Fe).

The given reaction is completed and balanced as shown below.

Fe+2AgC,H,0,Fe (CH3COO), +2Ag
