Carbon monoxide is always present in

A

automobile exhausts

B

volcanic gases

C

gases coming out of furnaces

D

all of these

Text Solution

Verified by Experts

The correct Answer is:

D

Carbon monoxide is produced when any carbon - containing compound (petrol, diesel, `CNG`), including carbon itself, is burned with an amount of oxygen insufficient for complete combustion:
`2(C ) + O_(2)(g) rarr 2CO(g)`
As automobile engines have become more efficient, `CO` production has diminished substantially. Thus, in that respect, the air inhaled on city streets is less harmful than it used to be because its `CO` content is lower.
