Detailed explanation-1: -The law of conservation of matter says that in chemical reactions, the total mass of the products must equal the total mass of the reactants.

Detailed explanation-2: -Chemical equilibrium is defined as a dynamic state where the concentration of all reactants remains constant. They may not be equal but they are not changing. In a chemical reaction, a double arrow indicates an equilibrium situation. Reactants are on the left and products are on the right.

Detailed explanation-3: -The law of conservation of mass states that in a chemical reaction mass is neither created nor destroyed. For example, the carbon atom in coal becomes carbon dioxide when it is burned. The carbon atom changes from a solid structure to a gas but its mass does not change.

Detailed explanation-4: -The law of conservation of mass states that during a physical or chemical change the total mass of the products is equal to the total mass of reactants. It can also be stated that matter cannot be created or destroyed.

Detailed explanation-5: -According to the law of conservation of matter, matter is neither created nor destroyed, so we must have the same number and type of atoms after the chemical change as were present before the chemical change.
