Answer :

GinnyAnswer
The given model `[tex]$2 CO + O_2 \rightarrow 2 CO_2$[/tex]` represents a chemical reaction.

Here is a detailed explanation:

1. Understanding the Chemical Equation:
- On the left side of the equation (`2 CO + O_2`), we have the reactants.
- On the right side of the equation (`2 CO_2`), we have the products.

2. Interpretation of the Reactants and Products:
- The reactants are 2 molecules of carbon monoxide (`CO`) and 1 molecule of oxygen (`O_2`).
- The product is 2 molecules of carbon dioxide (`CO_2`).

3. Chemical Process:
- This represents a process where carbon monoxide reacts with oxygen to form carbon dioxide.
- This is indicative of a chemical change where the bonds between atoms in the reactants are broken and new bonds are formed to create the products.

4. Verification of Conservation of Mass:
- The number of atoms on both sides of the equation is conserved, abiding by the law of conservation of mass.
- Reactants: 2 Carbon (C) atoms and 4 Oxygen (O) atoms
- Products: 2 Carbon (C) atoms and 4 Oxygen (O) atoms

Based on this detailed analysis, the correct answer to what the model represents is:

B. A chemical reaction
