Study Notes
States of Matter and Their Properties
- Solids have a definite shape and volume.
- Liquids have no definite shape but have a definite volume.
- Gases have no definite shape or volume.
- Solids have almost no movement of atoms, are incompressible and have low thermal expansion
- Liquids have moderate atom movement, are almost incompressible and have moderate thermal expansion
- Gases have free movement of atoms, are compressible and have high thermal expansion
Phase Changes
-
Melting: Solid to liquid
-
Freezing: Liquid to solid
-
Evaporation: Liquid to gas
-
Condensation: Gas to liquid
-
Sublimation: Solid to gas
-
Deposition: Gas to solid
-
Diagrams illustrating particle structures for each phase change should be studied.
Types of Matter
-
Matter:
- Can be physically separated? (yes/no)
- Is the composition uniform? (yes/no)
- Can it be chemically decomposed? (yes/no)
- This flowchart defines elements, compounds and mixtures.
Physical and Chemical Properties
-
Physical Property: A characteristic that can be observed or measured without changing the substance's chemical composition.
- Examples: color, odor, density, melting point, boiling point, hardness, solubility, conductivity, malleability (easily hammered into thin sheets), ductility (drawn into wire).
-
Chemical Property: A characteristic that describes how a substance reacts with other substances to form new substances.
- Examples: flammability (ability to burn), reactivity with acids or bases, ability to rust, oxidization.
Physical and Chemical Changes
-
Physical Change: A change in a substance's physical properties, but not its chemical composition.
- Examples: melting, freezing, boiling, dissolving, crushing, cutting.
-
Chemical Change: A change in a substance's chemical composition, resulting in new substances being formed.
- Examples: burning, rusting, cooking, oxidation, corrosion, reaction with another substance
Density
- Density is defined as mass per unit volume.
- This is measured in g/mL or g/cm3
- The mathematical formula relating mass (m), volume (v) and density (d) is: d = m / v
- Density is an intensive property
Atomic Structure
- Diagrams of atomic models and discoveries made by various scientists are to be studied.
Atomic Notation
- Atomic number and mass number are represented in atomic notation, eg. 12C(6).
- The number below the element symbol refers to the atomic number
- The number above the element symbol refers to the mass number
Average Atomic Mass
- The average atomic mass is calculated by taking the sum of the masses of the isotopes, multiplied by their relative abundances. .
- The formula is (mass * %abundance) + (mass * %abundance)... etc
Periodic Table Trends
- The periodic table is arranged by increasing atomic number.
- Elements in the same column (group) have similar chemical properties.
- Elements in the same row (period) have varying properties, but show trends in properties as the period progresses.
- Trends include atomic radius, electronegativity, ionization energy
Chemical Reactions
- Five basic types of chemical reactions, along with their general equation and characteristics, are to be studied.
Balancing Chemical Equations
- Understand how to balance chemical equations to ensure mass is conserved.
- Know how to state the types of reactions (synthesis, decomposition, single and double displacement).
