3 ph
Answer:
pH is a logarithmic scale. A solution with a pH of 2 has an H+ concentration 1000 times higher than a solution with a pH of 5. Officially pH is the negative logarithm of the molar concentration of the H+ ion in the solution.
Each number is a tenfold increase, so a solution having a pH of 2 is 10,000 times (or 10^4) more acidic than a solution having a pH of 6.
that doesnt make sense but neutral is 7 so id guess 3 and a half.. :S hope it helped :D
A pH of 6 is 1,000 times more acidic than a pH of 9. Each pH step is ten times than the next lower whole value. Since there are 3 steps between 6 and 9, 10 x 10 x 10 = 1,000.
100 times more acidic since pH number represents concentration of H+ atoms for exaple pH 1 = .1 concentration pH 2= .01 concentration pH 3= .o01 concentration etc.
Because the pH scale is a log base 10 scale the difference between 2 and 4 is 100x.
The concentration of H3O (hydronium) ions is 1000 times greater in a solution with a pH of 2 than the concentration in a solution with a pH of 5.
. Since the pH scale is determined by log it is 10 to the power of 3 more acidic so it's 1000 times more acidic
10 * 10 * 10
= 1000 times more

100
it consists of 10- 20 amino acids ....more than this is called polypeptides.....
My geological dictionary lists more than 7500 entries. Of which more than 10% will be discrete minerals. There is a list of the top 20 by composition, but that is a matter of opinion and location.
Uranus.
Humans have more rods than cones. There are almost 20 times more rods than cones in the human eye.

For more than 20 years of existence i just now had the time to visit here is not a correct grammar.
For more than 20 years of existence this may be my first time to visit here is not correct grammar.
"20 more than 20" means that you are adding 20 by 20. Then: 20 + 20 = 40 So 40 is 20 more than 20 because 40 - 20 = 20!
I know more than 20 codes so more than 20 p.s idont think you can count the codes
