PH = -log([H+])
[H+] = 10^(-pH)
[H+] = 10^(-8.78) = 1.65*10^-9
[H+][OH-] = Kw
Kw = 1.0*10^-14 at 25 degrees celsius.
[OH-] = Kw/[H+] = (1.0*10^-14)/(1.65*10^-9) = 6.06*10^-6
The concentration of OH- ions is 6.1*10^-6 M.
Answer:
2
Explanation:
There are 3 moles O2 in 1 mole CoH12O6 so 2 moles are consumed
It would be Rubidium chloride.
Soil.
Heterogeneous means is can be separated and soil can be taken apart and separated according to its contents. (Rocks, dirt, grass). <span />
Answer:
All of them affect the DNA
Explanation:
Chemicals are compounds that can pass through cell membranes and modificate the DNA, elevated temperatures can denaturalize the cell and therefore damage the DNA, ionizing radiation can pass through cell organelles and reach the nucleus affecting the DNA, and viruses inject its DNA into the genome and modify it.
