OCO

Another way of writing CO₂

Explanation:

A reaction equation has reactants on the left and products on the right.

The reactants are carbon and oxygen. The product is carbon dioxide.

C + O₂ → CO₂

You might see the equation both ways.

C + O₂ → OCO

C + O₂ in the products would mean no reaction has occurred. The problem can solid carbon can burn in oxygen, so a reaction will occur. For no reaction, you would put "NR" in the products.

OCO is the structural way of writing CO₂. Both have one carbon atom (C) and two oxygen atoms (O).

C + 2O is not possible. Oxygen, if alone, has to be at least O₂ because it's a diatomic molecule.
