Which of these has a higher hydrogen ion concentration? *

Genrish500 [490]

Answer:

pOH = 8.9

Explanation:

pOH+pH = 14

pH= 14- pOH

pOH = 8.9, pH=14-8.9 = 5.1

pOH = 5.5, pH=14-5.5 = 8.5

Than less pH , than more H+ ion concentration.

pH=5.1 <pH=8.5

pH=5.1 is more acidic solution

pH=5.1 or pOH=8.9 has a higher H+ concentration.

Which fatty acid salt is soluble in water solutions?

Oliga [24]

Answer is (A)
Pottasium and Sodium salts are soluble in water. When these soaps are added to hard water. Hard water contains calcium or magnesium ions and they form Magnesium or Calcuim salts. These salts of magnesium and calcium precipitates out and are insoluble in water. This precipitation is called as dirt (the exact word for dirt is not acceptable here). This process is considered as the disadvantage of soap as well as using hard water.

Is it possible to prove that something is real or true of you can’t directly observe it? If no, why not? If yes, how would you d

dangina [55]

Answer:

I don't know if you can directly prove it with evidence if you haven't observed it but you can maybe take an educated guess by the aftermath of it?

For example, you see a burnt log. At this time, people don't know what fire is. After we study the log, we could see that it takes extreme temperature in order to burn the log and that would help people see that there is a force like fire that can cause this. In a way, finding out that extreme temperatures burns stuff is another step closer to the discovery and proof of fire

I hope that makes sense
