Study Notes
Stoichiometry
- Study of the quantitative relationships between reactants and products in chemical reactions
- Involves calculating the amounts of substances required or produced in a reaction
Solids
- Have a fixed shape and volume
- Particles are closely packed and have a regular arrangement
- Examples: rocks, metals, and ice
Solubility
- Ability of a substance to dissolve in a solvent
- Factors affecting solubility:
- Temperature
- Pressure
- Concentration of the solvent
- Nature of the solute and solvent
Solutions
- Homogeneous mixtures of two or more substances
- Solvent: the substance in which the solute dissolves
- Solute: the substance that dissolves in the solvent
- Types of solutions:
- Gaseous solutions (e.g., air)
- Liquid solutions (e.g., sugar water)
- Solid solutions (e.g., alloys)
