Energy is the ability to cause a change in matter.
Formation of a precipitate is evidence of a chemical reaction.
A substance changes into a new kind of substance.
atoms in substances react with eachother
Generally, you know a chemical reaction has occured if there is a change in temperature, a change in color, a formation of a gas (bubbles), or any kind of flame.
Inflammability describes a chemical property (a chemical change).
yes it s an evidence that a chemical change has been occurred
A solution turning cloudy is evidence of a chemical change.
Because it is chemical change
It means it has evedince to change
Energy is the ability to cause a change in matter.
- A gas is evolved from reactants only if a chemical reaction occured.- The same situation for the color change.These are very possible signs but they are not absolute; many other factors must be studied.

Chemical
There are signs that you can see when a chemical change takes place. It is true that fizzing or foaming is evidence that a chemical change may have occurred.
You do, whenever you fry an egg.
A chemical change produces a form of matter that was not there before. Evidence of a chemical change could be changes in temperature, color, smell, and the production of a gas or a precipitate.
