Carbon burns in the presence of oxygen to give carbon dioxide. Which chemical equation describes this reaction?
Phoenix [80]

Answer: Option (B) is the correct answer.

Explanation:

It is known that for writing a chemical reaction equation, reactants are written on left hand side whereas products are written on right hand side.

And in between reactants and products a forward arrow is placed pointing towards the products.

Therefore, the reaction for carbon burns in the presence of oxygen to give carbon dioxide will be written as follows.

          Carbon + Oxygen \rightarrow Carbon dioxide

Here, carbon and oxygen atoms are the reactants whereas carbon dioxide is the product.
