This passage describes a chemical reaction. Read the passage. Then, follow the instructions below.

When car engines run, they often produce toxic gases such as carbon monoxide (CO). Modern cars use a device called a catalytic converter to reduce the amount of carbon monoxide released into the environment. The catalytic converter combines carbon monoxide and oxygen (O2) to form carbon dioxide (CO2). While too much carbon dioxide can harm the environment, this gas is less toxic than carbon monoxide.

Complete the table to classify the substances in this chemical reaction.

oxygen (O2)
carbon dioxide (CO2)
carbon monoxide (CO)
