Study Notes
Chemistry Overview
- Chemistry studies the composition, properties, and reactions of matter at the atomic and molecular level.
- Chemistry provides a foundation for understanding other scientific disciplines, such as biology, physics, and geology.
Chemistry in Pharmacology
- Chemistry explains the composition, properties, and reactions of pharmaceuticals, and how they interact with the body.
Importance of Chemistry
- Chemistry is sometimes called the central science because it connects and explains many aspects of the natural world.
Energy Source
- The main source of the world's energy is fossil fuels.
Group 14 Hydrides
- Examples of group 14 hydrides include methane (CH₄), silane (SiH₄), germane (GeH₄), and stannane (SnH₄).
Organic Commodity Chemicals
- The dominant raw-material source for organic commodity chemicals, such as solvents and polymers, is petroleum.
Greenhouse Gases
- Most anthropogenic (human-generated) greenhouse gases are carbon dioxide emissions.
Hydrocarbons
- Hydrocarbons can occur in three phases: solid (e.g., coal, asphalt), liquid (e.g., petroleum, gasoline), and gas (e.g., natural gas, methane).
