Final answer:
In an automobile's operation, gasoline, oil, and coolant are consumed, while carbon dioxide, water, and nitrogen oxides are primarily produced. The catalytic converter reduces harmful emissions like carbon monoxide and nitrogen oxides. Other byproducts include sulfur trioxide and VOCs, which can form secondary pollutants such as sulfuric acid and ozone.
Step-by-step explanation:
In the operation of an automobile, several chemicals are consumed and others are produced. The principal chemicals consumed include gasoline, oil, and coolant, while the typical chemicals produced encompass carbon dioxide, water, and nitrogen oxides. Oxygen is also consumed as it is a necessary component for the combustion process within the engine.
Emissions such as carbon monoxide and nitrogen oxides are significant because of their impact on environmental pollution and human health.
The catalytic converter plays an essential role in reducing these emissions. It promotes the complete combustion of carbon-containing compounds to carbon dioxide, a less harmful byproduct, while also substantially lowering the production of nitrogen oxides through catalyst-mediated reactions.
Furthermore, sulfur trioxide and volatile organic compounds (VOCs) can be produced due to the presence of sulfur in fossil fuels and the evaporation of unleaded gasoline, respectively. These substances can lead to the formation of secondary pollutants such as sulfuric acid and ozone.
