Are exothermic reactions violation of law of conservation of mass , because energy and mass are equivalent? Please clarify!
ThanksSimon Bridge said:Conservation of mass is a rule of thumb, not a fundamental law. It works because the energy gain or loss in chemical reactions is very small compared with the total mass of the reactants. The mass deficit gets obvious in nuclear reactions. It is total energy that gets conserved.
The Law of Conservation of Mass states that matter cannot be created or destroyed, it can only change forms. This means that in a closed system, the total mass of the substances before a chemical reaction must equal the total mass of the substances after the reaction.
The Law of Conservation of Mass is important because it is a fundamental principle of chemistry. It helps us understand and predict the outcomes of chemical reactions and is essential for balancing chemical equations.
The Law of Conservation of Mass and the Law of Conservation of Energy are closely related as they both state that in a closed system, the total amount of a certain quantity (mass or energy) remains constant. This means that mass can be converted into energy and vice versa, but the total amount of both remains the same.
Yes, the Law of Conservation of Mass is always true in a closed system. However, in some cases where nuclear reactions occur, a small amount of mass may be converted into energy, according to Einstein's famous equation E=mc^2. But in everyday chemical reactions, the Law of Conservation of Mass is always applicable.
The Law of Conservation of Mass is used in many practical applications, such as in waste management and recycling processes. It is also used in industries to ensure that chemical reactions are efficient and do not result in any loss of mass. Additionally, it is used in environmental science to track the movement and transformation of substances in ecosystems.
