Study Notes

Module 14: Solids, Liquids, and Gases

  • Kinetic theory is a key concept in understanding Solids, Liquids, and Gases
  • Melting and boiling points are important temperatures to know for different substances
  • Heat of fusion and vaporization are types of energy transfers related to phase changes
  • Sublimation is the process of a solid changing directly into a gas
  • Plasma is a high-energy state of matter
  • Thermal expansion is the increase in volume of a substance with an increase in temperature
  • Buoyancy and pressure are related to fluids
  • Viscosity is the measure of a fluid's resistance to flow
  • Boyle's and Charles's laws are important gas laws to know

Module 15: Classification of Matter

  • A substance is a pure sample of matter with fixed composition
  • Elements are the simplest form of matter with unique properties
  • Compounds are composed of two or more different elements
  • Mixtures are composed of two or more substances that are not chemically combined
  • Suspensions and colloids are types of heterogeneous mixtures
  • The Tyndall effect is the scattering of light by small particles
  • Solutions are homogeneous mixtures with uniform composition
  • Physical changes involve a change in state, but not composition
  • Chemical properties are characteristics of a substance that describe its ability to undergo a specific chemical change
  • Chemical changes involve a change in composition

Module 17: Elements and Their Properties

  • Metals are a class of elements with characteristic properties
  • Malleability is the ability of a metal to be shaped into thin sheets
  • Ductility is the ability of a metal to be stretched into thin wires
  • Metallic bonding is the type of bonding that occurs between metal atoms
  • Radioactive elements are unstable and undergo radioactive decay
  • Transition elements are metals that can form ions with different charges
  • Nonmetals are a class of elements with different properties
  • Metalloids are elements that exhibit intermediate properties between metals and nonmetals
  • Allotropes are different forms of an element with different physical properties
  • Semiconductors are materials with intermediate conductivity between metals and nonmetals

Module 18: Chemical Bonds

  • Chemical formulas are used to represent the composition of a compound
  • Chemical bonds are the attractive forces that hold atoms together
  • Ions are atoms or groups of atoms with an electric charge
  • Ionic and covalent bonds are two types of chemical bonds
  • Molecules are groups of atoms bonded together
  • Polar and nonpolar bonds/molecules have different properties
  • Oxidation number is a number that represents the number of electrons gained or lost by an atom
  • Binary compounds are composed of two different elements
  • Hydrates are compounds that contain water molecules
  • Chemical reactions involve the transformation of one or more substances into new substances
  • Chemical equations are representations of chemical reactions
  • Coefficients are used to balance chemical equations
  • Moles and molar mass are used to quantify the amount of a substance
  • Types of reactions include combustion, single displacement, and others

Review IPC chapters 17, 18, 19, and 21 with practice questions and formulas to help you prepare for your final exam. Focus on solids, liquids, gases, kinetic theory, and phase changes. Good luck!
