Question

Carbon sea 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 what is the correct answer? Would it be carbon, hydrogen, and methane or elements or carbon and hydrogen or elements and methane is a compound, carbon, hydrogen and methane all compounds or methane is an element and carbon and hydrogen or compounds.

Answer 1

From the information provided, the correct categorization is that **carbon and hydrogen are elements**, and **methane (CH₄) is a compound** made from these elements.

So the best answer based on the options you provided would be: **elements are carbon and hydrogen, and methane is a compound.**

Thus, the accurate breakdown is:
- **Carbon**: Element
- **Hydrogen**: Element
- **Methane (CH₄)**: Compound (made of carbon and hydrogen atoms)
