Question

which statement best compares a battery and a galvanic cell? (1 point)
a galvanic cells source of power is a battery in which a redox reaction produces electrical energy.
a batterys source of power is a galvanic cell in which a redox reaction produces electrical energy.

Explanation:

A battery is a device that consists of one or more galvanic cells. Galvanic cells use redox reactions to generate electrical energy. So, a battery's power source is the galvanic cell (which relies on redox reactions for electrical energy production).

Answer:

A battery’s source of power is a galvanic cell in which a redox reaction produces electrical energy.
