Final answer:
Liquids and solids are not included in equilibrium expressions such as Q and K, which is true. This is because in these reactions, the concentrations of pure liquids and solids remain constant. The statement is true.
Step-by-step explanation:
The statement that liquids and solids do not appear in chemical equilibrium expressions such as Q and K is true.
This is because in chemical equilibrium expressions for reactions involving pure solids and pure liquids, their concentrations are not included as they are considered to have a constant value.
In the case of solubility product constant (Ksp), only the concentrations of the ions in solution are taken into account, as the solid's concentration remains constant.
A substance with relatively strong intermolecular forces, a high melting point, and resistance to compression would be likely to be a solid.
These characteristics are due to the close proximity of the atoms or molecules within a solid and the significant forces between them, often causing them to arrange into a rigid lattice structure. This attribute contributes to a solid's definite shape and volume.
