Carbon (C) and hydrogen (H) are pure substances. Each is made of only one type of atom, but carbon atoms are different from hydrogen atoms. Carbon and hydrogen chemically combine to form methane (CH4).Based on this information:(1 point)%0D%0AResponses%0D%0A%0D%0Acarbon and hydrogen are elements and methane is a compound.%0D%0Acarbon and hydrogen are elements and methane is a compound.%0D%0A%0D%0Acarbon, hydrogen, and methane are all elements.%0D%0Acarbon, hydrogen, and methane are all elements.%0D%0A%0D%0Amethane is an element and carbon and hydrogen are compounds.%0D%0Amethane is an element and carbon and hydrogen are compounds.%0D%0A%0D%0Acarbon, hydrogen, and methane are all compounds.

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 indeed elements composed of only one type of atom, while methane (CH4) is a compound formed from the chemical combination of carbon and hydrogen atoms.
