Answer 2

Answer:

We can find out the formula of carbon dioxide as follows:

1. Carbon dioxide is a compound made up of carbon and oxygen elements. So, first we write down the symbols of carbon ( C ) and oxygen ( O ).
2. The the valency of carbon is 4 and the valency of Oxygen is 2. So, below the symbol C write 4 and below the symbol O we write 2.

⇒ C × 2 and O × 4

⇒ C₂ and O₄

⇒ C₂O₄

⇒ CO₂

Hence, the formula of Carbon Dioxide is CO₂.
