Question

Which of the following describes a compound? (Hint: Carbon and oxygen both appear on the periodic table.) A. a piece of pure carbon, containing only carbon atoms B. oxygen gas surrounding a solid piece of carbon C. a substance made of two oxygen atoms for each carbon atom D. carbon and oxygen atoms mixed without being bonded together

Answer 1

Hi,
The answer should be letter C, since a compound is made of atoms of two or more elements, in a defined ratio, bonded together.

Answer 2

Answer: Option (C) is the correct answer.

Step-by-step explanation:

A compound is a substance that contains two or more atoms chemically combined together in a fixed ratio by mass.

For example, carbon dioxide is a compound and its ratio by mass is 12:32 which is equal to 3:8.

Whereas when a substance with atoms of only a single element is known as a pure substance.

Therefore, we can conclude that the statement, a substance made of two oxygen atoms for each carbon atom describes a compound.
