1. which of the following is a device that generates electricity using a chemical reaction?

a. fuel cell
b. battery
c. solar panel
d. charging station
mark for review (will be highlighted on the review page)
(previous question) (next question >>)

Explanation:

To solve this, we analyze each option:

• Option A: A fuel cell generates electricity through electrochemical reactions (chemical reaction - related), but let's check others.
• Option B: A battery (e.g., electrochemical cell) produces electricity via chemical reactions (redox reactions) within it.
• Option C: A solar panel converts light energy to electricity (no chemical reaction).
• Option D: A charging station is for charging, not generating via chemical reactions.

Among these, a battery is a primary device that generates electricity using chemical reactions (redox reactions in its cells).

Answer:

B. Battery
