Question

a rocket uses an engine that creates thrust through the combustion of a liquid fuel and an oxidizer. what kind of rocket is this?
a. chemical rocket
b. nuclear rocket
c. atmospheric rocket
d. solid rocket

Explanation:

Chemical rockets generate thrust via the combustion of fuel and an oxidizer, which matches the description in the question. Nuclear rockets use nuclear reactions, atmospheric rockets rely on atmospheric air (no oxidizer carried), and solid rockets use pre-mixed solid fuel/oxidizer rather than separate liquid fuel and oxidizer.

Answer:

A. Chemical rocket
