Explanation

The least polluted gas chlorine.

The most polluted gas is carbon monoxide.

Explanation

To make an uncharged object have a negative charge, we must add electrons, which carry a negative charge.

This process increases the overall negative charge of the object.

This leading to an excess of electrons over protons.

This is because it has more landmass, which heats up faster than water.

This contributes to higher average temperatures.
