Couldn't tell you how, because this is a false presumption:
The law of mass conservation does FULLY apply to a chemical reaction.
Antoine Lavoisier (Pioneer of stoichiometry) already showed that, although matter can change its state in a chemical reaction, the total mass of matter is the same at the end as at the beginning of every chemical change.
D. always equal to the total mass of the products.
The mass of reactants is equal to the mass of products.
the law of conservation of mass states that matter can neither be created nor destroyed. so when a chemical reaction takes place, no matter is being destroyed. the mass of the reactants must equal the mass of the products.
true
False
Atoms cannot be added or lost in a chemical reaction.
The law of conservation of mass states that in a close container, when a chemical reaction occurs, no mass will be lost.
The Law of Conservation of Mass applies to chemical changes. When considering a chemical change this would mean that the total mass of all of the reactants in the chemical reaction is equal to the total mass of products in the chemical reaction.
The law of conservation of mass tells us that the mass of the products will equal the mass of the reactants in a chemical reaction.
The law of conservation of mass states that in a chemical reaction the mass of the reactants must equal the mass of the product.
Law of Conservation of Mass (aka Law of Conservation of Matter)
D. always equal to the total mass of the products.
In a balanced chemical reaction the total mass of the products always equals the total mass of reactants; this is the law of mass conservation.
The mass of all substances before a chemical reaction is equal to the mass of the substance after the reaction. This is under the law of conservation of mass.
The law of Conservation of mass states that 'mass is neither created nor destroyed in a chemical reaction'.
The principle of conservation of mass states that in a chemical reaction, the total mass of the reactants must equal the total mass of the products.
The mass of reactants is equal to the mass of products.
