Question

Carbon can be found in which of the following substances:

a) Water
b) Ammonia
c) Methane
d) Hydrogen peroxide

Answer 1

Carbon is present in methane (CH4), which is the only option among the given substances (water, ammonia, methane, and hydrogen peroxide) that contains carbon.

Step-by-step explanation:

The question concerns the presence of carbon in different substances. Specifically, carbon can be found in methane, which has the molecular formula CH4. Looking at the compounds listed:

• Water, H₂O, does not contain carbon.
• Ammonia, NH3, also lacks carbon.
• Methane, CH4, contains one carbon atom bonded to four hydrogen atoms.
• Hydrogen peroxide, H₂O₂, does not contain carbon either.

Therefore, the correct answer is (c) methane.
