13. a soil contains 30% smectite, 10% kaolinite, and 2% organic matter. calculate an estimated cec for this hypothetical soil.

estimated CEC for given hypothetical soil is  26.25 meq/100g.

Explanation:

Average CEC in smectite =  62.5 meq/100g. Since it ranges from(25-100 meq/100g)

Average CEC in kaolinite = 10 meq/100g.

Average CEC in organic matter = 325meq/100g.

Range(250-400 meq/100g).

Estimated CEC for given soil will be,

= 26.25 meq/100g.

for e2020. the answer would be some directions from the mountain range so we can find mt. whitney. to locate which direction is north, you should use a   compass. this would not only find mt. whitney, but also becuase of this long paragraph you would get points because it's not like anyone actually reads your work becuase once they read the first sentence it sounds dumb enough to not read becuase i'm not good at answering this but the answer is compass for your benefit.
