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​

Respuesta :

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​
