The statements correctly describes a compound and a mixture b. A compound can be separated chemically, whereas a mixture can be separated physically. Therefore, b. A compound can be separated chemically, whereas a mixture can be separated physically is correct.
A compound is a substance composed of two or more elements chemically bonded in fixed proportions.
The components of a compound are chemically combined, and a chemical reaction is required to break the bonds between the atoms.
This means that separating the elements in a compound involves breaking the chemical bonds, typically through chemical processes.
On the other hand, a mixture is a combination of two or more substances in which each substance retains its own chemical properties.
Mixtures can be separated by physical methods such as filtration, distillation, or magnetism.
Physical separation methods do not involve breaking chemical bonds but rather rely on differences in physical properties like size, solubility, or boiling point to separate the components of the mixture.
Therefore, option b accurately distinguishes between compounds and mixtures based on their separability through chemical or physical means.
