Compound Elements are chemically combined into a fixed
proportion
Name the 2 types of mixtures 1.) Heterogeneous
2.) Homogeneous
What's a Heterogeneous mixture? - Composed of different substances or the same
substance in different phases, as solid ice and liquid
water.
- whose parts are visible
, What's a Homogeneous mixture? - Involving substances in the same phase (solid,
liquid, or gas)
- Whose parts are not visible
What's a Physical Properties? Can be observed without changing the identify
(chemical composition)
Explains of physical properties. - Physical state: solid, liquid, gas
- Dissolving
- Qualitative: color, odor, solubility, hardness.
electrical conductivity
- Quantitative: mass, temp, melting pt., density
What's a Chemical Properties? - Does result in a change of the identity. (chemical
composition)
- it can only be observed via chemical reaction
What is a Chemical Reaction? The process of rearranging, removing, replacing, or
adding atoms to create a new substance.
What's the Extensive Property? Depends on the quantity of a substance
- Example: mass and volume
What's the Intensive Property? those to inherent of a particular substance. They are
independent of the amount of substance that is
being measured, and be used to identify an
unknown substance
- Example: Density, Freezing/Melting pt. Boiling pt.
Rules of significant figures: - (small decimal)
