POH = - log[OH^-]
pOH = - log[10^-6]
pOH = - (-6)
pOH = 6
knowing the ionization equation between pH and pOH in a solution at T = 25 degrees Celsius.
pH + pOH = 14
pH = 14 - pOH
pH = 14 - (6)
pH = 8.
I believe the pH of a substance with 10^-6 M of OH, would be 8.
C
hope this helps u to understand.
Precipitation would help distribute water all over the earth's surface, which gives animals and humans a source for water. Precipitation also helps plants grow which in turn provides humans with fresh air. Evaporation also benefits the different living organisms on earth by purifying the water. When water evaporates, pollutants are filtered and left behind , which makes it cleaner during precipitation.
Its B
because you know how much time each of them are getting
so hope this helps:)
