Study Notes
Matter
- Matter can exist in three states: solid, liquid, and gas
- Sublimation is the transition from solid to gas, and deposition is the reverse process
- Recombination and deionization can occur in plasma
- Shape and volume of matter can be definite or indefinite
- Molecular motion is a key characteristic of matter
Plasma
- Plasma is the fourth state of matter, most abundant in the universe
- Has positively charged ions (p+) and negatively charged electrons (e-), affected by magnetic fields
- Examples: ionized neon light, aurora, stars, and sun
Classification of Matter
- Pure substance: a sample of matter with constant composition and properties
- Mixture: a physical combination of two or more substances, separated by physical means
- Element: the simplest form of a substance, cannot be broken down further
- Compound: a substance composed of two or more different elements, combined through chemical means
Phase Changes
- Change in state from solid to gas is sublimation
- Change in state from gas to solid is deposition
- Change in state from solid to liquid is melting
- Change in state from liquid to gas is vaporization
Thermodynamics
- Zeroth Law of Thermodynamics: two systems in thermal equilibrium with a third system are also in thermal equilibrium with each other
- First Law of Thermodynamics: energy is conserved, not created or destroyed, but can be transformed from one form to another
- Second Law of Thermodynamics: entropy of an isolated system always increases over time
- Third Law of Thermodynamics: entropy of a perfect, solid, crystalline substance is zero at absolute zero temperature
Chemical Kinetics
- Study of reaction rates and mechanisms
- Reaction rate: change in concentration of a reactant or product with time
- Rate law: expresses the relationship of the rate of reaction to the rate constant and concentration of reactants
Organic Chemistry
- Ethers: a class of organic compounds with an oxygen atom bonded to two alkyl or aryl groups
- Aldehydes and ketones: classes of organic compounds with a carbonyl functional group
- Chirality: the existence of non-superimposable mirror images of a molecule
- Stereochemistry: the study of the three-dimensional arrangement of atoms in a molecule
Functional Groups
- Electrophile: an electron-deficient species that seeks electrons
- Nucleophile: an electron-rich species that donates electrons
- Carbocation: a species with a positively charged carbon atom
- Functional group: a specific group of atoms in a molecule that determines its chemical reactivity
