Question

All the chemical equations must be balanced. why? guess and write for 2 marks​

Answer 1

Explanation:

ALL THE EQUATIONS MUST BE BALANCED TO FOLLOW THE LAW OF CONSERVATION OF MASS IN WHICH MASS OF PRODUCTS AND REACTANTS MUST BE SAME .

PLZ MARK ME AS BRAINLIEST.

Answer 2

Answer:

hope this will help you.. please mark as brainiest...

Explanation:

• The representation of a chemical reaction in the form of substances is known as a chemical equation. The equation in which the number of atoms of all the molecules is equal on both sides of the equation is known as a balanced chemical equation.
• Chemical reaction is just a rearrangement of atoms. It can neither create nor destroyed during the course of a chemical reaction. Chemical equations must be balanced to satisfy the law of conservation of matter, that states that matter cannot be produced or destroyed in a closed system.
• The law of conservation of mass governs the balancing of a chemical equation. According to this law, mass can neither be created nor be destroyed in a chemical reaction and obeying this law the total mass of the elements or molecules present on the reactant side should be equal to the total mass of elements or molecules present on the product side. If the chemical equation is not balanced the law of conservation is not applicable.
