law of conservation of mass

• Principio fundamental en física y química que establece que la masa no puede crearse ni destruirse en un sistema cerrado durante cambios químicos o físicos ordinarios; la masa total permanece constante en una reacción o transformación.

A fundamental principle in physics and chemistry stating that mass cannot be created or destroyed in a closed system through ordinary chemical or physical changes; the total mass remains constant during a reaction or transformation.

   A scientific law stating that mass is neither created nor destroyed in a closed system during a chemical reaction.

   ley de conservación de la masa

   • According to the law of conservation of mass, the total mass of reactants equals the total mass of products.
   • In a closed flask, the law of conservation of mass ensures that the mass remains constant after a reaction.
   • Students learn the law of conservation of mass in introductory chemistry classes.
