  1. Reactants
    The starting substances that undergo change in a chemical reaction
  2. Products
    The substances produced as a result of a chemical reaction
  3. Diatomic Molecules
    • Elements that appear as Diatomic molecules in nature must be present as the
    • diatomic, not single atoms in a chemical equation: H2, O2, N2, F2, Cl2, Br2, I2
  4. Law of Conservation of Mass
    Mass is neither created nor destroyed in an ordinary chemical reaction
  5. Chemical Equation
    A representation for a chemical reaction that uses chemical symbols and chemical formulas instead of words to describe the changes that occur in a chemical reaction.
  6. Balanced Chemical Equation
    A chemical reaction that has the same number of atoms of each element involved in the reaction on each side of the equation
  7. Equation Coefficent
    A number placed to the left of a chemical formula in a chemical equation that changes the amount but not the identity of a substance.
  8. Synthesis Reaction
    A chemical reaction in which a single product is formed from two or more reactants

    X + Y → XY
  9. Decomposition Reaction
    A chemical reaction in which a single reactant is converted into two or more substances

    XY → X + Y
  10. Single replacement Reaction
    A chemical reaction in which one element within a compound is replaced by another element

    X + YZ → Y + XZ
  11. Double Replacement Reaction
    A Chemical Reaction in which two compounds exchange parts with each other and form two new compounds

    AX + BY → AY + BX
  12. Combustion Reaction
    A chemical reaction in which a substance reacts with Oxygen (usually from air) that proceeds with evolution of heat and usually also a flame.
  13. Chemical Stoichiometry
    The study of quantitative relationships among reactants and products in a chemical reaction
  14. Limiting Reactant
    The reactant in a chemical reaction that is entirely consumed during them chemical reaction
  15. Theoretical Yield
    The maximum amount of a product that can be obtained from given amounts of reactants in a chemical reaction if no losses or inefficiencies of any kind occur
  16. Actual Yield
    the amount of a product actually obtained from a chemical reaction
  17. Percent Yield
    the ration of the actual yield in a product to its theoretical yield, multiplied by 100 (to give percent)
