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
What else can I help you with?
What happens when a clear substnace undergoes a chemical change?
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.
What happens to a substance in physical change?
it means figure it out yourself!
What happens when a pure substance undegoes a chemical change?
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.
What process happens when a substance undergoes a 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.
What happens after physical and chemical changes have occurred?
The substance will remain in its current state unless acted upon in such a way as to cause a physical or chemical change.

What happens when a substance undergoes a physical change?
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.

What happens when a substance changes state from a solid or liquid?
This change in the state of matter (liquid to solid) is called freezing.This change in the state of matter (solid to liquid) is called melting.They are physical change, the chemical nature of the molecules is not changed.

What happens when substances goes through a phase change?
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.
What happens to the chemical makeup of matter when it undergoes a physical change?
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.
What happens after physical and chemical changes have occurred?
The substance will remain in its current state unless acted upon in such a way as to cause a physical or chemical change.
What happens to a substance during a chemical change or chemical reaction?
substances can change to a solid, gas or liquid. solid - precipitate gas - fumes liquid - color change Either way, since its a chemical reaction, there always will be a change in the chemical composistion of a substance.
