methane is an element and carbon and hydrogen are compounds.
methane is an element and carbon and hydrogen are compounds.

carbon, hydrogen, and methane are all compounds.
carbon, hydrogen, and methane are all compounds.

carbon and hydrogen are elements and methane is a compound.

Answer 1

The correct response is:

carbon and hydrogen are elements and methane is a compound.

This is because carbon (C) and hydrogen (H) are both pure substances that consist of only one type of atom, making them elements, while methane (CH4) is formed when these elements chemically combine, making it a compound.
