At the time, chemists were exploring the formation of calx (an oxide), predicting that metals lost mass as they were burnt. As the wick burned down and the candle melted, the weight of the jar and its contents remained the same, thereby proving his pioneering theory. One of Lavoisier’s experiments entailed placing a burning candle inside a sealed glass jar. ![]() When we balance equations, we need to make sure that the same number of atoms of each element is present on each side of the equation. ![]() Chemical manufactures can increase the efficiency by applying the law of conservation of mass to their laboratory practices. If scientists know the quantities and identities of reactants for a particular reaction, they can predict amount of products that will be made. ![]() The law of conservation of mass is very important to the study and production of chemical reactions. If we account for all reactants and products in a chemical reaction, the total mass will be the same at any point in time in any closed system.ĭiscovery of law of conservation of mass helped to turn chemistry into the respectable science it is today. It was a French chemist named Antoine Lavoisier who formulated the concept of the conservation of mass – the idea that matter can neither be created nor destroyed, only rearranged.
