GinnyAnswer
In a catalytic converter, various chemical reactions take place to convert harmful pollutants in car exhaust into less harmful substances. Among the given options, the change that does not occur in a catalytic converter is:

A. carbon dioxide → carbon

Explanation:
1. In a catalytic converter, carbon monoxide (CO) is converted into carbon dioxide (CO2), which is a less harmful product (option B).
2. Nitrogen oxides (NOx) are converted into nitrogen (N2), which is a less harmful product (option C).
3. Unburned hydrocarbons are converted into carbon dioxide (CO2) and water, reducing their harmful effects (option D).
4. However, the conversion of carbon dioxide (CO2) into carbon (C) does not occur in a catalytic converter, making option A the correct answer.

Therefore, in a catalytic converter, the transformation from carbon dioxide into carbon does not take place, unlike the other given options.
