The arrows B, C, and E represent the process of cooling.
Solid state: In the solid state, the molecules are arranged in a regular and fixed pattern. The molecules in a solid are closely packed that is the solid particles can not move.
Liquid state: In the liquid state, the molecules are present in an irregular pattern. The molecules are closely packed but particles can move.
Gaseous state: In the gaseous state, the molecules are present in an irregular manner. The molecules of gases are not closely packed and can move freely.
Therefore, the solid changes to liquid on heating, and the liquid changes to solid after cooling.
Liquid changes to a gaseous state on heating while gases changes to liquid on cooling.
Solid changes to gas on heating and gases change to solid after cooling.

The number of H atoms in 3(NH₄)₂CrO₄ = 24
<h3>Further explanation </h3>
The empirical formula is the smallest comparison of atoms of compound forming elements.
A molecular formula is a formula that shows the number of atomic elements that make up a compound.
(empirical formula) n = molecular formula
Subscripts in the chemical formula indicate the number of atoms
