In this theory, gas molecules are deemed to be at constant random motion and have perfectly elastic collisions with each other. They bounce of each other. These particles are assumed to have a spherical shape. Also, there are no attractions between the molecules.<span />
Answer:
please mark as brainliest!!
Explanation:
ans: gas
The same number of particles in a gas spread further apart than in the liquid or solid states. The same mass takes up a bigger volume . This means the gas is less dense. Density also depends on the material.

All atoms except H and O are balanced.
The oxidation number of Cl changes from 7 to 3. The change in the oxidation number is 4.
The oxidation number of O changes from -1 to 0. The change in oxidation number per O atom is 1.
Total change in the oxidation number for 2 oxygen atoms is 2.
To balance the increase in oxidation number with decrease in the oxidation number, multiply H

The oxygen atoms are already balanced.
This is the balanced chemical equation
