Pre-AP Chemistry
Unit 1
1.1 Structure and Properties of Matter
A matter is anything that takes up space and has mass and can't be destroyed.
1.2 Developing a Model of Matter
A matter can solid , liquid, gas .
the example above show an solid matter .
2.3 Chromatography
2.1 Mixing and Unmixing
The part of the mixture that passes through the filter paper is called the Filtrate
2.2 Atoms, Molecules and Particles
In evaporation process, the state of liquid changes to gas.
2.5 Distillation and Electrolysis
Separation of homogenous liquid solution
2.4 Partial Pressure
1.5 Heat Transfer
the energy required to raise the temperature of one gram of a substance by one degree Celsius
q=mc∆T
1.3 Confidence in Measurement
The percent error formula is
1.4 Relating Mass and Volume
density equation: Density = mass/volume
1.6 Phase Diagrams
A graph of pressure versus temperature that shows the conditions under which the phases of a substance exist
1.7 Heating Curves
a plot of temperature versus time for a substance where energy is added at a constant rate
1.8 - 1.9 Properties of Gasses (Ideal)
pressure vs. volume of gas =inversely proportional
pressure vs. gas particles = directly proportional
pressure vs. temperature = directly proportional
volume vs. temperature = directly proportional
unit 2 are summarize in the photo
2.6+2.7 Intermolecular Forces
Forces that operate between molecules.
London dispersion forces, dipole - dipole interaction, hydrogen bonding.
2.8 Evaporation and Intermolecular Forces
Intramolecular forces
forces hold the molecule together or form bonds.
Intermolecular forces
Forces that operate between molecules
2.9 Molecular Geometry
2.10 Spicy Chemistry (Isomeres)
Compounds with the same formula but different structures
2.11 Solubility
hydrophilic
having an affinity for water; readily absorbing or dissolving in water
hydrophobic
having an aversion to water; tending to coalesce and form droplets in water
