Answer:

The answer is "5.18 ".

Explanation:

It's a question of chemistry. Therefore, the following solution is provided:

We will first determine the solution's pOH. The following can possible:

The concentration of Hydroxide ion [OH^{-}] = 1.5\times 10^{-9}\ M

pOH =?\\\\pOH = -\log [OH^{-}]\\\\pOH = -\log 1.5\times 10^{-9}\\\\pOH = 8.82\\\\

Furthermore, the pH of the solution shall be established. It was provided as follows:

pOH = 8.82\\\\pH =?\\\\pH + pOH = 14\\\\pH + 8.82 = 14\\\\

When collecting all the like terms:

pH = 14 -8.82\\\\pH = 5.18

Therefore, the solution of pH is 5.18.

1. How would you use your results to tell the relative ages of the rock layers in a new section of strata?
DanielleElmas [232]

Answer:

The more  worn-out the rock is, the older it is

Explanation:

Hello,

The different layers a rock has could be useful to date it, as long as the deepest layers account for the oldest rocks because they haven been worn out due to erosion and others natural events. Thus, one can say that the more  worn-out the rock is, the older it is when we want to analyze a new section of strata.

Best regards.
