100 ml of carbon dioxide gas is diffused through a porous pot in 20 seconds. How much time will it take to diffuse 100ml of helium gas through the same porous pot at the same temperature?

66.33 seconds

Explanation: rate of diffusion is inversely proportional to the square root of the relative molecular mass of the gas.

answer: -

reaction:

na + cl ⇌ nacl

balanced chemical equation:

na + 2cl ⇌ nacl2

sodium + clorine goes to form sodium chloride (table salt).

the product is nacl2.

and the reactants are na and cl.

(note: if you don’t know what ⇌ means, read below: -

⇌(double head arrow) means reversible reaction).

every chemical equation adheres to the law of conservation of mass, which states that matter cannot be created or destroyed. therefore, there must be the same number of atoms of each element on each side of a chemical equation.
