15. Within a voltaic cell,___ takes place at the anode, electrons flow to the cathode, where
takes place.
A. reduction; current
B. oxidation; reduction
C. reduction; oxidation
D. oxidation, current

B. oxidation; reduction

Explanation:

A voltaic cell is electro-chemical cell in which chemical energy is converted into electrical energy.

1. This cell utilizes chemical reaction to generate electric.\

2. there two electrode anode and cathode

3. At Anode oxidation occurs

4. At cathode reduction occurs

5. chemical is present in the cell which is electrolyte which completes the circuit of the voltaic cell.

Based on above discussion

At anode oxidation takes place

At cathode reduction takes place.

Hence, correct option is B. oxidation; reduction

the answer is a! (2.9 x 10^-18 j) hope i could someone. : )
