Options

• carbon dioxide and water

• carbon monoxide

• methane

• carbon dioxide and methane

• ethane

Answer 1

Catalytic converters are fitted into automobiles to reduce emission of harmful gases. Catalytic converters change unburnt hydrocarbons into carbon dioxide and water.

Explanation:

Catalytic converters in automobiles contain catalysts such as platinum, palladium, and rhodium that help convert unburnt hydrocarbons into less harmful substances, primarily carbon dioxide (CO₂) and water (H₂O). They also convert carbon monoxide (CO) and nitrogen oxides (NO_x) into carbon dioxide and nitrogen gas, thereby reducing harmful emissions from vehicle exhausts.
