Question
Which of the following substances is both a molecule and a compound?
Correct Answer
Option C is the correct answer.
Detailed Explanation
NH3 (ammonia) is a molecule because it consists of multiple atoms bonded together, and it is a compound because it contains two different elements (nitrogen and hydrogen). O2, N2, and Cl2 are molecules but not compounds because they consist of only one element.
Hint
Look for a substance that contains atoms of more than one element.
