Law of Conservation of Mass

Chemistry is a physical science that studies substances, energy, and how they interact. When studying these interactions it is important to understand the law of conservation of mass

Briefly, the law of conservation of mass means that a substance can not be created or destroyed, but it can change its shape.

In chemistry, the law is used to balance chemical equations. In the case of reactants and products, the number and type of atoms must be the same

The law of conservation of mass is that it can not produce or destroy substances in closed systems or isolated systems. You can change the shape but it is preserved

In the context of chemistry research, the law of conservation of mass states that, in a chemical reaction, the mass of the product is equal to the mass of the reactant.

Clarification: Isolated systems are systems that do not interact with the surrounding environment. Therefore, the quality contained in the isolated system remains the same regardless of conversion or chemical reaction. The results may be different from the original results, but the quality never exceeds you or falls below. Before conversion or reaction

Since scientists help to understand that substances do not disappear by reaction (as there is a possibility of chemical disappearance), conservation law of mass is important for the progress of chemistry.

History recognizes that many scientists have discovered the law of conservation of mass. In 1756, Russian scientist Mikhail Lomonosoff noticed this in his diary. In 1774, French chemist Antoine Lavoisier carefully recorded the experiment and proved the law. Some people know that the law of conservation of mass is the law of Laboasier.

When defining the law, Lavoisier said: "An atom of an object can not be created or destroyed, but it can be moved and turned into a different particle."

The law of conservation of mass indicates that the total mass present before the chemical reaction is the same as the total mass existing after the chemical reaction, that is, the mass is preserved. For his burning experiments, Lavoisier developed a conservation law of mass that he observed the quality of his original material. Air. Historically, this is a concept that scientists can not understand. If this law is right, will we be able to reduce big wood pieces to small ash piles? Trees are considerably heavier than ashes. From this observation, the scientists believe that the quality has disappeared, but the graph \ (\ PageIndex {1} \) indicates that word burning follows the law of mass protection. Scientists were not thinking about gases that play an important role in this reaction.

Let's talk about mass preservation law, mass conservation law only shows what it is like. Even if we change substances, we will not permit the creation of substances from the beginning or the destruction of substances to be eliminated. So, how does chemical reaction handling chemical reactions help? This is the scenario we are accustomed to using the conservation law of mass.

Substances are not generated or destroyed by changes in chemical substances. This very important principle is called mass conservation law. This method applies to ordinary chemical reactions (as opposed to nuclear reactions where substances can be converted into energy). During a chemical change (reaction), atoms of one or more substances (reactants) are only "rearranged". As a result of these rearrangements newly different substances (products) are formed. All the original atoms are still present. It is because of conservation of mass that we can write balanced chemical equations. Such an equation can predict the quality of the reactants and products that will participate in the chemical reaction. In this experiment, we use an aqueous solution of three different compounds to cause two separate and different chemical reactions. All responses will change
