Study Notes
Classification of Matter
- Matter consists of substances that can be classified into different categories.
- Substances made up of identical atoms are known as elements.
- Mixtures comprise two or more substances that can be easily separated.
- Compounds are formed when two or more elements chemically combine.
Types of Mixtures
- Homogeneous mixtures have a uniform composition throughout, making it difficult to distinguish different components.
- Heterogeneous mixtures consist of visibly different materials that can be easily distinguished.
Examples of Matter
- Chalk is classified as a compound.
- Copper is an example of an element.
- Granite is identified as a heterogeneous mixture.
- Vinegar is recognized as a homogeneous mixture.
Other Forms of Matter
- Pond water is categorized as a suspension, where solid particles are suspended in liquid.
- Water, salt, and sugar are all examples of compounds.
- Gold is classified as an element.
Specialized Mixtures
- Permanent press fabric is an example of a heterogeneous mixture.
- Soft drinks are homogeneous mixtures.
- Paint is classified as a colloid, which contains small particles that do not settle.
Unique Substances
- Fog and gelatin are forms of colloids.
- A river delta is identified as a suspension.
Fundamental Concepts
- All substances are composed of atoms.
- In a colloid, a beam of light can be seen passing through due to its dispersed particles.
- A solution is a homogeneous mixture of particles that are so small they cannot be seen and do not settle.
Physical Changes and Mass Conservation
- Applying energy to substances can lead to physical changes, exemplified by melting ice.
- The principle of conservation of mass states that mass is conserved before and after a chemical change.
- Distillation is a process used to separate solids from liquids.
Distinction of Mixtures
- Heterogeneous mixtures contain distinguishable materials.
- Homogeneous solutions have particles undetectable without a microscope.
- Suspensions are liquid mixtures with visible particles that eventually settle.
Compounds and Elements
- Compounds are formed from the combination of two or more different elements.
- Matter where all atoms are identical is classified as an element.
