Study Notes
Chemical Terms and Definitions
- Etch: A chemical process that creates marks or designs by cutting into a solid surface.
- Element: The simplest form of matter, consisting entirely of one type of atom.
- Compound: A substance formed from the chemical bonding of two or more different elements.
- Physical Change: Involves a change in the arrangement or mixing of particles without altering the particles themselves at the atomic level.
- State of Matter: Refers to the three physical forms of matter: solid, liquid, and gas.
Chemical Processes
- Dissolve: Process in which a substance mixes at the molecular level with another substance, resulting in a uniform solution.
- Chemical Reaction: A transformation in which substances undergo a change to form new substances through the rearrangement of atoms, also known as a chemical change.
- Precipitate: An insoluble solid that is formed from the reaction of two liquid solutions when mixed.
Chemical Concepts
- Chemical Equations: Notation that represents the reactants and products involved in a chemical reaction.
- Reactants: The initial substances that participate in a chemical reaction before any transformation occurs.
- Products: The final substances generated as a result of a chemical reaction.
Basic Building Blocks
- Atom: The smallest unit of matter that retains the properties of an element, often considered the basic building block of all substances.
- Molecule: Formed when two or more atoms are chemically bonded together.
Fundamental Principles
- Law of Conservation of Mass: States that mass is conserved in a chemical reaction; it is neither created nor destroyed, ensuring that the mass of reactants equals the mass of products.
- Closed System: A physical system where matter and energy cannot enter or leave.
- Open System: A system where matter and energy can flow in and out.
Energy Changes in Reactions
- Thermal Energy: Refers to the energy that arises from the motion of particles in an object, influencing the temperature of the object.
- Exothermic Reaction: A type of reaction that releases energy, typically in the form of heat or light.
- Endothermic Reaction: A reaction that absorbs energy from its surroundings, usually resulting in a temperature decrease in the environment.
Waste Management
- Reclaim: The process of retrieving and recovering materials from waste for reuse, promoting sustainability and resource conservation.
