Study Notes
Branches of Chemistry
- Inorganic Chemistry studies non-carbon compounds and materials.
- Organic Chemistry focuses on carbon-containing compounds.
- Physical Chemistry combines principles of physics and chemistry to understand molecular behavior.
- Analytical Chemistry involves qualitative and quantitative analysis of substances.
- Biochemistry explores chemical processes in living organisms.
- Environmental Chemistry examines chemical processes occurring in the environment.
- Industrial Chemistry applies chemical principles to manufacturing processes.
- Theoretical Chemistry uses mathematical models to understand chemical behavior.
- Medicinal Chemistry involves drug design and discovery.
Various Fields in Chemistry
- Medicinal Chemistry focuses on developing pharmaceuticals.
- Petrochemistry studies the chemistry of petroleum and its derivatives.
- Polymer Chemistry investigates synthetic and natural polymers.
- Nanotechnology involves manipulating matter at the molecular or atomic level.
Discontinuity of Matter (4 Main Ideas)
- Matter consists of discrete particles rather than continuous materials.
- These particles exhibit distinct properties based on their size and arrangement.
- Changes in matter occur through the rearrangement of these particles.
- Observations at the atomic level explain macroscopic phenomena.
States of Matter
-
Solid
- Particles are compact and arranged orderly.
- Strong intermolecular forces.
- Exhibits vibration but maintains shape.
- Low energy level.
-
Liquid
- Particles are close together but not orderly.
- Moderate intermolecular forces.
- Particles slide past each other.
- Moderate energy level.
-
Gas
- Particles are far apart and randomly arranged.
- Very minimal intermolecular forces.
- Particles move quickly in all directions.
- High energy level.
Pure Substances & Mixtures
-
Elements
- Simplest form of matter made of one kind of atom.
- There are 118 known elements, 94 occurring naturally.
-
Compounds
- Composed of two or more different elements combined in fixed ratios.
- Can be broken down into simpler forms via chemical reactions.
-
Homogeneous Mixtures (Solutions)
- Substances are evenly distributed throughout and cannot be easily distinguished.
- Uniform composition and properties exist.
-
Heterogeneous Mixtures
- Substances are not evenly distributed, allowing for distinguishable parts.
- Composition and properties can vary throughout the mixture.
-
Types of Mixtures
- Colloids: Particles that are larger than those in solutions but smaller than those in suspensions.
- Suspensions: Particles that are large enough to be seen; they settle at the bottom over time.
