A physical change doesn't change what the substance is but for chemical change a new substance is formed and energy is either given off or absorbed.
Answer:
Baking soda mixed with Vinegar
Explanation:
This is a chemical reaction that I have seen in my daily life. Vinegar is acidic while baking soda is a base. The 2 mix together to form carbonic acid and sodium acetate from sodium and bicarbonate ions.
Explanation:
Compounds are the species in which all the components react chemically to form a molecule which has a different property from the constituting elements.
On the other hand, mixture are the species in which the components do not react chemically and the original properties of the components are not lost.
<u>Thus, separation of the mixture into its components can be done by the physical means while separation of the compound into its components can be only possible by the chemical means.</u>
They are called ISOTOPES.
