  2. Definition for: Products
    Subtance formed from reactants
  3. Definition for: Chemical Equation
    Is a shorthand expresion for a chemical change
  4. Definition for: Balanced equation
    Contains the same number of each kind of atom on each side of the equation
  5. Definition for: Combination reaction
    two reactants combine to give one product
  6. Definition for: Single-Displacement reaction
    one element reacts with a compound to replace one of the elements of that compound, yielding a different element and a diffrent compound
  7. Definition for: Double-Displacement Reaction
    two compounds exchange partners with each other to produce tow diffrent compounds
  8. Definition for: Exothermic reactions
    Reations that liberate (release) heat
  9. Definition for: Endothermic reations
    Reactions that absorb heat
  10. Definition for: Heat of reation
    The quantity of heat produced by a reation
  11. Definition for: Hydrocarbons
    Mixtures that contain only hydorgen and carbon
  12. Definition for: Activation energy
    The amount of energy to start a chemical reation
  13. Definition for: Molar Mass
    The Sum of the atomic masses of all the atoms in an element or compound
  14. Definition for: Stoichiometry
    the area of chemistry that deals with quantitative relationships among reatants and products is knows as Stoichimetry.
  15. Definition for: Theoretical yield
    The reaction is the calculated amount of product that can be botained from a given amount of reactant, according to the chemical equation.
  16. Definition for: Actral yield
    is the amount of product that we finally obtain
  17. Definition for: Percent yield
    is the ration of the actual yield to the theoretical yield multiplied by 100
  18. Definition for: Kinetic-Molecular Theory
    • A theory based how gases behave.
    • States that

    • 1. Gases consist of tiniy particles
    • 2. The sistance between particles is large compared with the size of the particles themselves
    • 3. Gas particles have no attraction for one another
    • 4. Gas particles mone in straight linesin all direction, colliding freqently with one another and with the wall of the container
    • 5. no energy is lost by the collision of a gas particle with another gas particle or the walls of the container. All colitions are elastic
    • 6. the average conetic energy (KE) of a particle is expressed by the equation
  19. Definition for: Ideal gas
    A gass that behaves exactly as outlined by the theory (KMT).
  20. Define: Diffusion
    The ability of two or more gasses to mix spontaneoulsly until they form one the form a uniform mixture.
  21. Define: Effusion
    is the process by which a gas molecules pass thorugh a very small hole
  22. Define: Graham's Law of effusion
    the rate of effusion was dependent on the density of a gas.
  23. Define: Pressure
    is defined as force per unit area.
  24. Define: Atmospheric Pressure
    the gases in the atmosphere exert a pressure known as
  25. Define: Borometer
    A device that measures atmosphere pressure
  26. Define: 1 atmosphere
    is the pressure exerted by a column of mercury 760 mm high at a temperature 0 degree celcius
  27. Define: Boyle's law
    The relationship of a P and V is known as Boyle's Law. V 1/p or P1V1 = P2V2
