Answer:

Explanation:

Without the presence of decomposers and detritivores in a forest ecosystem organic material would not break down and the nutrients would no longer be available to other organisms. Moreover, dead plants and animals will pile up. Because, detritivores eat fragments of dead matter in an ecosystem and decomposers break down dead organisms so the environment will no longer be clean.

Black coffee has a pH around 5; hand soap has a pH of 10. How many times more acidic is coffee relative

Anon25 [30]

Answer:

$\boxed {\boxed {\sf 10^5 \ or \ 100,000 \ times \ more \ acidic}}$

Explanation:

The pH scale stands for the power or potential of hydrogen. It measures how acidic or basic a solution based on the concentration of hydrogen ions and a scale from 1 to 14.

This scale is unique because it is logarithmic. So, every time the pH changes by 1 on the scale, the actual concentration of the solution increases or decreases by a tenfold.

So, a solution with a pH of 7 is ten times more acidic than a solution with a pH of 8. This can be translated to:

$10^ {difference \ in \ pH}$

The black coffee has a pH of 5 and the hand soap has a pH of 10. We want to find how many times more acidic coffee is, so we subtract 5 from 10 and get 5. The difference in pH is 5.

$10^5=100,000$

Coffee is <u>10⁵ or 100,000 times more acidic than hand soap.</u>
