This refers to the law of conservation of mass. It is generally used when balancing chemical reactions as it states that the total mass of the substances undergoing a chemical reaction is always the same: before, during, and after the chemical reaction. The "closed system" part means that no matter is gained from the surrounding environment nor lost to it.
Keep in mind though that this law isn't valid for nuclear reactions, in which the total mass of the system does vary. In any case, you can always use the law of conservation of energy, as matter itself is a form of energy (see the famous equation E=mc2).
The statement is an observation. It describes the phenomenon that occurs when iron rusts in a closed container, indicating that the total mass remains constant despite the chemical reaction. This aligns with the law of conservation of mass, which states that mass is neither created nor destroyed in a closed system.
This is the law of mass conservation. If the external surface of the container react with air the law is not applicable, a new compound is formed.
The metal will rust over time but the mass of the container as a whole. The law of conservation of mass is not violated.
According to the Law of Conservation of Mass, matter can neither be created nor destroyed, only change forms. Therefore, if you burn magnesium inside of a closed container, the mass will remain the same. ---- However you will get heavier ash than you had magnesium as the Oxygen in the air in your container will be transfered. But Total Mass is conserved.
The law that states mass cannot be created or destroyed in chemical or physical changes is the Law of Conservation of Mass, also known as the Principle of Mass Conservation. This law implies that in a closed system, the total mass remains constant before and after any chemical or physical process, even if the substances undergo a change in form or state.
In a closed container the mass of reactants (wood) and products (carbon dioxide, water, ash) remain unchanged; this is the low of mass conservation.
This is the law of mass conservation. If the external surface of the container react with air the law is not applicable, a new compound is formed.
The metal will rust over time but the mass of the container as a whole. The law of conservation of mass is not violated.

Conservation of mass. It means that in a closed system, the amount of mass doesn't change over time.
It doesnt. Law of Conservation of Mass.
The mass of reactants is equal to the mass of products.
According to the Law of Conservation of Mass, matter can neither be created nor destroyed, only change forms. Therefore, if you burn magnesium inside of a closed container, the mass will remain the same. ---- However you will get heavier ash than you had magnesium as the Oxygen in the air in your container will be transfered. But Total Mass is conserved.
During chemical processes in a closed system the mass remain constant.
That is a law, specifically the law of conservation of mass. This states that matter can neither be created nor destroyed in a chemical change. This was proved in Lavosier's experiment where he determined that the total lass of the products formed by burning were equal to the mass of the matter burned and oxygen consumed.
The law of conservation of mass, which states that in a closed system, mass is neither created nor destroyed, it can only change form. This means that in a chemical reaction that takes place in a closed system, the mass of the reactants equals the mass of the products.
