♔♔Why is mass conserved in chemical reactions?❦❦❦​
Allushta [10]

Answer:

Atoms are not created or destroyed by chemical reactions. Also, matter is neither created nor destroyed, it just changes form. Matter cannot be created or destroyed. ... The Law of Conservation of Mass states that in a chemical reaction the total mass of reactants is equal to the total mass of products.

Explanation:

According to the law of conservation of mass, the mass of the products in a chemical reaction must equal the mass of the reactants. The law of conservation of mass is useful for a number of calculations and can be used to solve for unknown masses, such the amount of gas consumed or produced during a reaction.

For example, when wood burns, the mass of the soot, ashes, and gases equals the original mass of the charcoal and the oxygen when it first reacted. So the mass of the product equals the mass of the reactant.
