Which of the following gases will have the highest rate of effusion at a given temperature?

cl2
he
o2
ne

He

Explanation:

Movement of of gaseous molecules through tiny hole is called effusion.

At a given temperature, rate of effusion of gases is related with the molar mass (M) of the gases as:

Therefore, higher the molar mass of the gas, lower will the rate of effusion.

Molar mass of = 70 g/mol

Molar mass of He = 4.0 g/mol

Molar mass of = 32 g/mol

Molar mass of Ne = 20.17 g/mol

Since, molar mass of He is lowest among given, so rate of effusion of He will be the highest.

atomic number of carbon is 6

electronic configuration of carbon is 1s²2s²2p²

orbital diagram of carbon is as shown here in the image.

one negative thing it that it can kill water animals. another negative thing is it can cause the destruction of ecosystem. one way water pollution can be reduced is to conserve energy.
