Question

7. Forest fires are natural sources of
(A) Carbon monoxide
(B) Hydrocarbons
(C) Hydrogen sulphide
(D) Nitrogen dioxide​

Answer 1

Answer:

Carbon Monoxide(CO)

Explanation:

Carbon monoxide (CO) is a colorless, odorless, and tasteless flammable gas that is slightly less dense than air. It is toxic to animals that use hemoglobin as an oxygen carrier (both invertebrate and vertebrate) when encountered in concentrations above about 35 ppm, although it is also produced in normal animal metabolism in low quantities, and is thought to have some normal biological functions. In the atmosphere, it is spatially variable and short-lived, having a role in the formation of ground-level ozone.
