FINAL REVIEW

 

  1. Yes
  2. Forward and reverse rates
  3. products
  4.       (N2)

                 (NO)2   (H2)2

  1. No
  2. Chemical reactions resist change and will do the opposite of whatever is done to it.
  3. Products  Forward
  4. Products  Forward
  5. Products Forward
  6. Reactants Reverse

 

  1. Reactants

 

  1.      (.380) (.540)   = Q =  3.88 x 10 -4

 

             (23)2

                 This is bigger than Keq so there is more products than at equilibrium and it will be going in reverse.

  1. Acids give off H+ and bases give off OH-
  2. Acids the same  and bases take on H+
  3.   H3O+
  4.        (H3O+)2 (SO4-2)

                   (H2SO4)

17.  Weak because mostly reactant which in the molecular form and not H3O+

      18.  Yes

      19.    Kw  =  (H3O+)  (OH-)

      20.  1 x 10 -14           1 x 10-7

      21.  1 x 10 -14 = (H3O+) (6.25 x 10 -9) =  1.6 x 10 -6.  Acid

      22.  –log(H3O+)   = 2.9

      23.   POH   = 5.4 =  -log (OH-)

              pH         = 14 – 5.4 =  8.6

1.      Homogenous

2.      Solute

3.      Aqueous

4.      electrolytic

5.      1 liter of water equals 1 kilogram

6.          3.0 =   moles   =     .6 moles  x  MW/1mole               (look up MW on periodic            

                              .2L                                                                    Chart)                               

               200ml x 1/1000 =  .2 L                

10.    Supersaturated

11.    Exothermic
