Answer 1

B.) CO2 that is the chemical formula for carbon dioxide

Answer 2

CO2

Step-by-step explanation:

Carbon dioxide is made by the combination of carbon and dioxide.

For the formation of carbon dioxide the reaction that takes place is as follows:

C + O2 ------> CO2

Here the valency of carbon is 4 and that of oxygen is 2.

A double bond is formed between an atom of carbon and two atoms of oxygen as shown in the image and this results in the formation of carbon dioxide, CO2.
