when a substance undergoes a chemical change the original form cannot be recognized and it could get total new properties.
A chemical change occurs when a new substance forms that has different chemical properties than the original substance.
physical change
the product's properties usually and may differ from the properties of the reactants. Example-salt-sodium, a soft explosive metal and chlorine, a toxic gas. make salt.
That is officially known as a chemical change. It is distinct from a physical change which does not alter a substance into a different substance.
During a physical change, the matter of what the substance is made out of doesn't change.
Chemical changes alter the chemical makeup of a substance... physical changes only change the way something looks, it does not modify the chemical properties.

When a substance changes but still retains its original properties, the change is called a physical change. If it didn't retain its original properties, then it went through a chemical change.
They may be similar or totally different.
In a physical change, the substance is still the same substance after the change. But in a chemical change, the substance became another substance with different properties from the original substance.Physical change is changing the appearance of something. Example - Rip a piece of paper - physical change. Burn gasoline - chemical change.
A chemical change produces a new substance with different properties than the original substance.
PHYSICAL CHANGE:It is a temporary change in which no new substance is formed and can be reversed by simple means.CHEMICAL CHANGE:it's a permanent change in which the substance give rise to original substance having different compositions and properties. it is irreversible and accompanied by energy change.

In a physical change, the chemical composition of the substance undergoing the change remains the same. In a chemical change, atoms are rearranged, forming new products with their own unique chemical compositions and properties, different from the original substance or substances.
Yes, a chemical change produces new chemicals with properties different from those of the original
