Student Must Know…
Key Terms...
Writing a reaction / Structure of a Reaction
  • Compounds are chemically bonded atoms, whereas mixtures are physically combined atoms.
  • The physical states of the reactants and products and the correct state symbols
  • Subscripts cannot be changed to balance an equation

Reaction Types
  • The general form of the 5 types of reactions
    • Combination / Synthesis
    • Decomposition
    • Single Displacement
    • Double Displacement
    • Combustion
  • Exothermic reactions give off energy, endothermic reactions absorb energy

Cool Decomposition

Precipitate Formation

Law of Conservation of Mass
  • The total mass of the reactants equals the total mass of the products
  • Reactions must be balanced because mass must be conserved
  • To balance a reaction you change the coefficients

Molar Ratios / Stoich
  • Molar Mass is determined by adding the molecular weights of each atom in a compound
  • Molar ratio is determined by the coefficients of the balanced chemical reaction
