Study Notes

Classification of Matter

Compounds: Substances formed from two or more elements that are chemically bonded. Examples include:
- Sand
- Table salt (sodium chloride)
- Pure water (H₂O)
- Carbon dioxide (CO₂)
- Lithium iodide (LiI)
- Hydrogen peroxide (H₂O₂)
Elements: Pure substances that cannot be broken down into simpler substances. Examples include:
- Gold (Au)
- Oxygen (O₂)
- Silver (Ag)
- Lead (Pb)
Homogeneous Mixtures: Mixtures with a uniform composition throughout. Examples include:
- Lemonade
- Brass (an alloy of copper and zinc)
- Salt water (solution of NaCl in water)
- Air (a mixture of gases)
- Coffee
- Gatorade
Heterogeneous Mixtures: Mixtures with a non-uniform composition where different components can be seen. Examples include:
- Soil
- Italian salad dressing
- Apple pie
- Chocolate chip cookie
- Chicken soft taco from Taco Bell

Key Characteristics of Matter Classification

Compounds exhibit distinct properties from the individual elements they comprise.
Mixtures retain the properties of their individual components.
Homogeneous mixtures appear uniform and consist of the same phase, while heterogeneous mixtures contain distinct phases.
