Answer:
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:
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.
Coffee is <u>10⁵ or 100,000 times more acidic than hand soap.</u>
Answer:
On a simplified level, photosynthesis and cellular respiration are opposite reactions of each other. In photosynthesis, solar energy is harvested as chemical energy in a process that converts water and carbon dioxide to glucose. Oxygen is released as a byproduct.
Answer:
Refer below.
Explanation:
It is a beneficial species types association. The two life forms in the relationship profit by it. This typically happens in light of the fact that every living being needs something different has, so they can exchange.
Flowers that require fertilization are in a mutualistic relationship with the insects that fertilize them. The bloom gives nectar to the bugs to eat, and the creepy crawlies fertilize the blossoms.

Answer:
19 gram of molecule are present in NaOH
Explanation:
because of 10 gram we put in NaOH it is incomplete if we put 9 gram in NaOH it is complete NaOH =11+8+1 =19
