What is the chemical formula of carbon dioxide?
Answer and explanation
Correct answer: CO₂
Carbon dioxide contains one carbon atom and two oxygen atoms. Chemical symbols are written as C for carbon and O for oxygen, while the subscript 2 shows that two oxygen atoms are present; hence CO₂, option B, is correct. O₂ is oxygen, N₂ is nitrogen, and Ar is the symbol for the element argon, so those alternatives describe different substances.
