In a galvanic cell________________?
Correct answer: A. Chemical energy is converted into electricity
- A. Chemical energy is converted into electricity
- B. Chemical energy is converted into heat
- C. Electrical energy is converted into chemical energy
- D. Electrical energy is converted into heat
Explanation
A galvanic cell converts the chemical energy released by a spontaneous redox reaction into electrical energy. The likely confusion is with an electrolytic cell, where electrical energy is converted into chemical energy.

About Redox Reactions
Redox reactions involve oxidation and reduction occurring together, with electrons transferred between species or oxidation numbers changing. The topic covers assigning oxidation states, identifying oxidizing and reducing agents, balancing redox equations by oxidation number or half-reaction methods, and connecting chemical changes with galvanic and electrolytic cells.
