The answer to your question is given below

Explanation:

1. Data obtained from the question include:

Hydrogen ion concentration, [H+] = 1x10^-9M

pH =..?

pH = - log [H+]

pH = - log 1x10^-9

pH = 9

2. Data obtained from the question include:

pOH = 3

pH =.?

Recall:

pH + pOH = 14

pH + 3 = 14

Collect like terms

pH = 14 - 3

pH = 11

3. Data obtained from the question include:

Hydroxide ion concentration, [OH-] = 1x10^-2M

pH =..?

First, we shall determine the pOH. This is illustrated below

pOH = - Log [OH-]

pOH = - Log 1x10^-2

pOH = 2

Finally, we can obtain the pH as follow:

pH + pOH = 14

pOH = 2

pH + 2 = 14

Collect like terms

pH = 14 - 2

pH = 12

4. Data obtained from the question include:

pOH = 7

pH =.?

Recall:

pH + pOH = 14

pH + 7 = 14

Collect like terms

pH = 14 - 7

pH = 7

the earth would become to overheated and everything alive on it will eventually die from overheating. plants will eventually die as well, water will evaporate, and it will be nothing but a hot planet without anything living on it.
