Detailed explanation-1: -Oxygen molecule (O2) is made up of the same type of oxygen atoms. Hence, oxygen is an element. On the other hand, carbon dioxide (CO2) is made up of one atom of carbon and two atoms of oxygen. Hence, carbon dioxide is a compound.
Detailed explanation-2: -Q6) Give three reasons why-carbon dioxide is considered a compound while carbon is an element.

Carbon dioxide is formed from two different types of elements: carbon and oxygen. Carbon dioxide is the result of covalent bonding between one carbon atom and two oxygen atoms.
Detailed explanation-4: -The answer is c) a compound. Carbon dioxide is a compound since it is composed of a carbon atom chemically bonded to two oxygen atoms.
Detailed explanation-5: -A molecule of carbon dioxide (CO2) is made up of one carbon atom and two oxygen atoms.
