Question

look at the diagram. if the larger gray atom represents carbon and the smaller white atom represents oxygen, fill in the chemical formulas in the boxes to complete the chemical equation.

Explanation:

Step1: Identify the first reactant

The first reactant is a single - carbon atom. Its chemical formula is $C$.

Step2: Identify the second reactant

The second reactant is an oxygen molecule which consists of two oxygen atoms. Its chemical formula is $O_{2}$.

Step3: Identify the product

The product is a carbon - dioxide molecule which has one carbon atom and two oxygen atoms. Its chemical formula is $CO_{2}$.

Answer:

Box 1: $C$
Box 2: $O_{2}$
Box 3: $CO_{2}$
