If two solutions differ in their [h3o+] by a factor of 2.0, the difference in their ph will be 2.0.

False

Explanation:

We can use an example to ilustrate the problem. For example we can use a concentration values of and (a difference of 2). Using the pH formula we can calculate the pH value for each concentration.

The difference between these values is 0.18 . Due to the logarithm, the difference in the concentration is not the same in the pH values.

the mantle

explanation:

earth is divided into three layers: the crust or the outermost layer on which we live; the underlying, middle layer - the mantle - and the core (the innermost layer of earth).
