Key Concepts Covered

➡️ Law of Conservation of Mass – The principle states that mass cannot be created or destroyed in a chemical reaction within a closed system.
➡️ Closed System – A system where no mass enters or leaves during a chemical reaction, essential for observing conservation of mass.
➡️ Atomic Theory – The understanding that atoms are neither created nor destroyed during reactions, underpinning the conservation principle.
➡️ Reactants and Products – Identifying how mass is conserved across chemical reactants transforming into products.
➡️ Gas Evolution and Mass – Techniques for tracking mass in experiments involving gases and reaction products.
