Study Notes
Chemistry
- Chemistry is the branch of science that focuses on the composition, structure, properties, and changes of matter.
Law of Conservation of Mass
- Mass remains constant throughout a chemical change; the total mass of reactants equals the total mass of products.
Reactants
- Reactants are the substances that undergo transformation during a chemical reaction.
Products
- Products are the new substances formed as a result of a chemical change, often with different properties than the reactants.
Energy Changes
- Chemical changes involve the absorption or evolution of energy, often in the form of heat or light, indicating exothermic or endothermic reactions.
