Law of Conservation of Mass

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.

There are 10 grams of red mercury oxide and when heated in a flask in an oven until completely decomposed, it is decomposed into elemental mercury and oxygen and the mass of liquid mercury is 26 grams. What is the oxygen quality of the formed gas? Well, we started with 10 grams of mercury dioxide, now, here the reaction material reaction is broken down into its products. We are the same as we have mercury I say there is. 26 grams, is it okay? Since we do not know how much oxygen we want to release, we do not know that the law of conservation of mass does not destroy substances that we can not make, so here the quality is the product It should be equal to quality. When we subtract 26 from both sides we get a given 74 grams of oxygen, so the quality of protection law is very easy and explains the simplest concept so we can not create a lean substance . You can not destroy substances

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 combustion experiments, Lavoisier developed a conservation law that he observed the quality of his original material - glass container, tin and air - mass of material produced - glass container, glass tin, Remaining 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.

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
