The elements of a chemical compound can be separated only by chemical means, but not by physical means.
Only physical means; chemical means alters the chemical composition.
No, physical
A Compound.
physical because a chemical change means it can never form back
no, it can not be separated by a physical process.
Of course Element. Iron = Fe It cannot be separated by physical or chemical means and hence is an element Mixtures can be separated by physical means and compound by chemical means
No, chemical changes cannot be reversed by physical changes. Chemical changes involve the formation of new substances with different properties, while physical changes only affect the state or appearance of a substance without changing its chemical composition. Once a chemical change occurs, it cannot be undone by a physical change.
Elements
No.

Yes, mixtures can be separated by simple chemical means such as filtration, distillation, and chromatography. These techniques take advantage of the physical or chemical properties of the components in the mixture to separate them effectively.
