How does a balance chemical equation demonstrate the law of conversation of mass? It shows that all compounds remain bonded after the reaction, it shows that the properties of elements stays the same after the reaction, it shows that no atoms have been gained or lost during the reaction and it shows the only physical change follow the law of conversation of mass

A balanced chemical equation demonstrates the law of conservation of mass by satisfying the principle that matter cannot be created or destroyed in a chemical reaction. Thus, the equation ensures that there is an equal number of atoms of each element on both sides of the equation.

A balanced chemical equation represents the reactants and products involved in a chemical reaction. Each element is represented by its respective chemical symbol, and the number of atoms of each element is denoted by a coefficient. The coefficients are adjusted such that the number of atoms of each element is the same on both sides of the equation.

By balancing the equation, it ensures that all compounds remain intact after the reaction. The properties of the elements involved also stay the same before and after the reaction, as the chemical equation only represents the rearrangement of atoms, not a change in their fundamental properties.

The law of conservation of mass further implies that no atoms are gained or lost during the reaction. This principle is upheld in a balanced chemical equation, as the total number of atoms of each element is the same on both sides of the equation.

Any physical changes accompanying the chemical reaction, such as changes in state or appearance, also follow the law of conservation of mass. While the equation itself does not directly represent physical changes, if any occur, the total mass of the reactants will be equal to the total mass of the products, as no mass has been created or destroyed.

In summary, a balanced chemical equation demonstrates the law of conservation of mass by ensuring the same number of atoms of each element on both sides of the equation, representing that compounds remain intact, and upholding the principle that no atoms are gained or lost during the reaction. Furthermore, any physical changes accompanying the reaction follow the law of conservation of mass.
