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.
The process by which <em>two species evolve</em> as a <em>response</em> to <em>changes in one another over time</em> is called, "coevolution" thus the correct answer is that it is an example of <u><em>COEVOLUTION</em></u>
It might change over time to compensate fir its environment
Answer:
Noble gases
Explanation:
Noble steam, any of the seven chemical elements that make up the periodic table in group 18.
Within normal conditions, noble gases are colorless, odorless, tasteless, and nonflammable gases. The noble gases are grouped according to their boiling point in the periodic table. Noble gases, from incandescent lamps to excimer lasers, are commonly used in distinct areas.
