Understanding the Conservation of Mass
The concept of conservation of mass is a fundamental principle in chemistry. This law dictates that mass is neither created nor destroyed during a chemical reaction. It states that the mass of reactants in a chemical equation must equal the mass of the products. This worksheet focuses on helping students apply this principle through various scenarios and calculations involving chemical reactions.
Key Principles of Conservation of Mass
- Reactants and Products: In any chemical reaction, the total mass of reactants equals the total mass of products.
- Chemical Equations: Write and balance chemical equations to demonstrate equal mass on both sides.
- Closed Systems: Ensure that reactions are in closed systems to accurately measure mass before and after the reaction.
