Study Notes
Mixtures
-
Mixtures can be classified as homogeneous or heterogeneous.
-
Homogeneous mixtures have a uniform composition throughout, such as concrete and sugar dissolved in water.
-
Examples of homogeneous mixtures include:
- Concrete
- Sugar mixed with water
- Pacific Ocean
- Air inside a balloon
- Tap water in a glass
- Salt dissolved in pure water (NaCl + H2O)
- Muddy water
- Brass (copper mixed with zinc)
-
Heterogeneous mixtures consist of different components that are not uniformly distributed, such as:
- Orange juice with pulp
- Soil
- Chex mix
Pure Substances
-
Pure substances can be classified as elements or compounds.
-
Elements are substances that cannot be broken down into simpler forms, including:
- Iron fillings (Fe)
- Aluminum (Al)
- Magnesium (Mg)
- Chromium (Cr)
-
Compounds are chemical combinations of two or more elements in fixed proportions, examples include:
- Limestone (CaCO3)
- Acetylene (C2H2)
- Pure water (H2O)
- Benzene (C6H6)
- Baking soda (NaHCO3)
Summary
- Understand the distinction between homogeneous and heterogeneous mixtures, as well as between pure substances and their classifications.
- Familiarity with practical examples helps in categorizing matter accurately.
- Recognition of common compounds and elements is essential for scientific understanding and application.
