Hint: A chemical reaction rearranges the constituent atoms of the reactants to create different substances as products.
Complete answer:
Change in the colour of reaction.
Here we will take an example of iron and copper sulphate.
\[CuS{O_4} + Fe \rightleftarrows FeS{O_4} + Cu\]
Here the colour changes from blue to light green.
Second property is change in texture:
When any substance differs in their physical state, for example, we take a piece of wood, and we do some polishing. it appears different and softer. It has changed its texture.
Third property is lustre:
the lustre of an element is defined as the way it reacts to light. Luster is a quality of metal. Almost all the metals are lustrous.
Fourth is change in the odour:
We are aware that whenever ammonia is created, it has a pungent smell. This makes us identify what substances are formed. Whenever more than two compounds or elements are mixed a scent of odour is present.
Fifth is change in temperature:
A change in temperature is characteristic of chemical change. During an experiment, one could dip a thermometer into a beaker or Erlenmeyer flask to verify a change.
Sixth Formation of precipitate:
It may be one of the most common signs of a chemical reaction taking place. It’s a solid that forms inside of a solution or another solid.
Note:
A precipitate should not be confused with suspensions, which are solutions that are homogeneous fluids with particles floating about in them. During physical change, water must be heated.
