Even though you are burning the log, none of the mass is destroyed. The mass of the log and the oxygen involved in burning it will just be the sum total of all the by products; namely CO2, Carbon, and Water Vapor.
No, because of the law of conservation of mass.
NO
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.
In a closed container the mass of reactants (wood) and products (carbon dioxide, water, ash) remain unchanged; this is the low of mass conservation.
There are several laws of conservation; please clarify which one you mean. For example, there is the law of conservation of mass, of energy, of momentum, of rotational momentum, of electrical charge, and others.
When something is burned, its mass remains the same. The substances that are being burned undergo chemical reactions, where they are broken down into different molecules. However, the total mass of the substances before and after the burning process remains constant due to the law of conservation of mass.
Atoms cannot be added or lost in a chemical reaction.
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 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.
The Law of conservation of Energy applies to mass as mass is a form of energy, E=mc2.
it conserves mass
Law of Conservation of mass(atomic mass). As mass can be considered relative to energy, therefore Law of Conservation is also correct but Law of conservation of mass is is much more accurate because here mass is a much more accurate term that is required here. Here, since, we are balancing molecules, then we require atomic or molecular mass.
