Chemistry is a fascinating branch of science that deals with the interactions and relationships between matter and energy. It includes the creation of materials through joining elements in atom form into clusters called molecules, and the reactions that then take place between these resultant materials. In the process of researching and understanding these interactions, various rules, or laws of science, have been developed. One of these precepts of science that applies to all chemical, physical or other interactions is called the law of conservation of mass.


1. The Definition

The law of conservation of mass states that when chemical reactions take place in a closed system, matter can never be created or destroyed but instead is simply transformed. The matter may change form, be transformed in its chemical composition, or lose or modify many of its properties, but the quantity of the mass entering into the chemical equation is always the same as the quantity in the end.
