When a chemical reaction occurs,

the physical and chemical properties of the reactants are the same as the properties of the products

the compounds can be separated by physical means

O a phase change takes place

the physical and chemical properties of the products are different from the reactants

Let us study about chemical reaction

Explanation:

Chemical reaction '

It is a reaction in which two or more substances react to form some new substance.

The substances that react are called "reactants " and the new ones that are formed are called "products ".

A + B - --> C + D

(reactants) (products)

In a chemical reaction:

Reactants undergoes a chemical change. The products cant be separated by physical method. For every chemical reaction there is some identification property. During chemical reaction, energy changes occur. During chemical reaction : It is seen that physical and chemical properties of the products are different from the reactants
