Question

Carbon burns in oxygen to form carbon dioxide. The properties of carbon dioxide are :
(A) Similar to carbon
(B) Similar to oxygen
(C) Totally different from both carbon and oxygen
(D) Much similar to both carbon and oxygen

Answer 1

Hint: An element is a pure substance that is composed of only one type of atoms. A substance formed due to the combination of different atoms of different elements is known as a compound. A compound does not retain the properties of elements from which it has been formed.

Complete Step by step solution
Carbon dioxide is a gas composed of carbon atoms and oxygen atoms and it is present in earth’s atmosphere being a trace gas. It is soluble in water and possesses a sharp as well as acidic odor. Carbon dioxide is also used by plants in the process of photosynthesis and in order to make their food. The solid form of carbon dioxide is known as dry ice and it is used as a refrigerant. It is also beneficial as an abrasive in the dry-ice blasting. Carbon dioxide is the most lived greenhouse gas all over the earth’s atmosphere.
The reaction taking place between oxygen molecule and carbon atom forming carbon dioxide is as follows,
 $ C + {O_2} \to C{O_2} $
As carbon dioxide is made up of different atoms of different elements such as carbon and oxygen, it is a compound. As carbon dioxide is a compound, its properties will completely differ from the atoms of elements it has been formed from, which are carbon and oxygen atoms. Therefore, the correct answer is option C that is totally different from both carbon and oxygen.

Note
The structure of the carbon dioxide molecule is $ O = C = O $ . Carbon dioxide naturally occurs in the atmosphere and it is one of the gases that leads to global warming. It is formed along with carbon monoxide during the combustion of wood or fossil fuels.
