Question

Which remains the same after the chemical reaction takes place

Answer 1

Dear Student,

According to law of conservation of mass, the total mass of reacting components taking part in the reaction remains constant or same.
In a chemical reaction the total mass of all the reactants and products (substances) ​taking part in the reaction remains the same. Also, the number of atoms in a reaction remains the same. Mass cannot be created or destroyed in a chemical reaction.

Regards.
