Question

When fossil fuel is burned, which of the following occur?

• A. $N_2\left(g\right)+O_2\left(g\right)⟶2NO\left(g\right)$
• B. Formation of sulphur oxides
• C. Acid rain
• D. All of above.

Answer 1

The correct option is D All of above.

Oxides of sulphur are produced when sulphur containing fossil fuel is burnt.
When fossil fuel is burnt,dinitrogen and dioxygen combine to yield significant quantities of nitric oxide $\left(NO\right)$ and nitrogen dioxide $\left(N{O}_2\right)$ as given below:
$N_2\left(g\right)+O_2\left(g\right)⟶2NO\left(g\right)$
With the increased use of fossil fuels, a large amount of carbon dioxide gets released into the atmosphere which makes the rain slightly acidic thus causing to form acid rain.
