What is the law of conservation of mass and how does it relate to chemistry

The law of conservation of mass states that in a chemical reaction, matter cannot be created or destroyed. This means that the total mass of the reactants must be equal to the total mass of the products. In other words, the amount of matter before a chemical reaction is the same as the amount of matter after the reaction, even if the substances have changed form or appearance.

This law is fundamental to chemistry because it is the basis for balancing chemical equations and understanding the chemical reactions. It helps chemists and scientists predict the amount of product that can be obtained from a reaction, as well as troubleshoot and identify any errors in their experiments. The importance of this law is highlighted in the field of environmental chemistry, where it helps scientists understand the conversion of matter from one form to another and how it impacts the ecosystem.
