when a pure substance undergoes a chemical change it is no longer that same substance. A chemical change changes the identity of the substance. Hope i helped
It is no longer that same substance. A chemical changes the identity of the substance. Individual atoms cannot be broken down into smaller parts by normal physical or chemical change.
it means figure it out yourself!
When a pure substance undergoes a chemical change, its molecular structure is altered, resulting in the formation of one or more new substances with different chemical properties. This process is typically accompanied by observable signs such as color change, gas production, or temperature change. Unlike physical changes, where the substance retains its original identity, chemical changes are often irreversible under normal conditions. Examples include combustion, rusting, and fermentation.
The substance will remain in its current state unless acted upon in such a way as to cause a physical or chemical change.
During a chemical change, the substance's chemical composition is altered, resulting in the formation of new substances with different properties. Bonds between atoms are broken and rearranged to form new molecules. This process is typically accompanied by the release or absorption of energy.

During a physical change, the substance's chemical composition remains the same. It undergoes a change in physical properties such as shape, size, or state (solid, liquid, gas) without forming a new substance. Examples include melting, freezing, boiling, and dissolving.

When a substance changes state from a solid to a liquid, it undergoes melting where it gains enough energy to break the bonds holding its particles together. When it changes from a liquid to a gas, it undergoes vaporization where it gains enough energy to overcome the forces of attraction between its particles.

Melting: the substance changes back from the solid to the liquid. Condensation: the substance changes from a gas to a liquid. Vaporization: the substance changes from a liquid to a gas. Sublimation: the substance changes directly from a solid to a gas without going through the liquid phase.
During a physical change, the chemical makeup of matter remains the same. The atoms and molecules that make up the substance do not change their identities, only their arrangement or state. This means that no new substances are formed during a physical change.
