Study Notes
Classification of Matter
- Matter can be categorized into pure substances and mixtures
Pure Substances
- Made up of only one type of particle (atom or molecule)
- Elements and compounds are considered pure substances because they have a fixed composition and properties
- Examples: oxygen (O2), water (H2O), sugar (C6H12O6)
Mixtures
- Made up of two or more different substances, not chemically combined
- Properties and composition can vary
Basic Concepts of Chemistry
- The concept of "mole" is a basic concept of chemistry
- "Mass" is a basic concept of chemistry
- "Matter" is a basic concept of chemistry
- "Energy" is a basic concept of chemistry
- "Particle" is NOT a basic concept of chemistry
Pure vs Impure Substances
- Pure substances have a fixed composition and properties, while impure substances have varying composition and properties
- Pure substances are homogeneous, while impure substances are heterogeneous
