The principle that mass can neither be created nor destroyed in a chemical reaction, meaning that the total mass of the reactants is equal to the total mass of the products
Summary
The Law of Conservation of Mass is a fundamental principle in chemistry that asserts that mass is neither created nor destroyed during a chemical reaction. This means that the total mass of the reactants must equal the total mass of the products, which is crucial for understanding chemical processes. This law was established by Antoine Lavoisier in the 18th century and has since become a cornerstone of modern chemistry. Understanding this law is essential for students as it lays the groundwork for more complex topics such as stoichiometry and thermodynamics. It helps in predicting the outcomes of chemical reactions and ensures accurate calculations in laboratory settings. By mastering the Law of Conservation of Mass, learners can better appreciate the intricate balance of matter in the universe.
