a chemical reaction causes breakage and bonding of the atoms and molecules in any substance that consists of matter.
New substances are formed when matter undergoes a chemical reaction.
Both chemicatl & physical changes occurs. Beacose after new substance the new substance can be liquid or in precipitate form.After forming new substance the new substance would react or not it is not known.
Physical changes confer to the change in the physical nature of the substance. Atoms rearrange them to form a new substance identical to the previous one. Example - If you met a solid wax, you still get a wax, but in liquid form. The atoms of the solid wax rearranged themselves to form a new product (liquid wax) but the substance was same that is wax. So no new substance was formed.Source:
No, a new substance is normally formed
When metals burn in air they form metal oxides.
New substances are formed when matter undergoes a chemical reaction.
A new substance is formed only after a chemical change.
It can form a new substance that can help us..
Correct; a chemical change produces a new substance, or in other words, an existing substance changes into a different substance.

A substance changes into a new kind of substance.

No, freezing is a change in STATE of a substance (from liquid to solid), the solid is NOT a new substance.
A new substance is formed only after a chemical change.
it just creates a new substance!
produce new substance that have properties diffrent from those of the original substance.
