Question

Can reactants in a chemical reaction produce substances which have less mass and still follow the Law of Conservation of Mass. For EX: if (NaCo3+ 2HO4—-> CO2 + something else) and the reactant weighed more than the product.. does it still follow the Law of Mass and how did it lose mass while still following the Law of conservation of mass??

Answer 1

Yes, the Law of Conservation of Mass still applies in this case. In a chemical reaction, the total mass of the reactants must be equal to the total mass of the products. It may seem like the products have less mass than the reactants, but this is because some of the mass has been converted into other forms of energy, such as heat, light, or sound. This is known as mass-energy equivalence, and it is described by Einstein's famous equation, E=mc^2.

Answer 2

Law of Conservation of Mass?

The Law of Conservation of Mass states that in any chemical reaction, the total mass of the reactants must be equal to the total mass of the products. This means that mass cannot be created or destroyed during a chemical reaction.

Therefore, in the reaction you presented, the mass of the reactants cannot be greater than the mass of the products. If it appears that the products have less mass than the reactants, it could be due to a loss of gas during the reaction or the formation of a solid that is less dense than the reactants. In any case, the total mass of all the reactants and products must remain constant, as per the Law of Conservation of Mass.
