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>

After reading the article, are you convinced of an answer to the main question of the article: “Could our distance from nature a
Lena [83]

Yes, our distance from nature and our chronic immunological discontent could be related. Nature may be the cause of allergic problems.

<h3>What is an allergy?</h3>

Allergy is a common immune response produced by certain substances that alter the stability of the immune system.

Allergy may be caused by different materials present in nature that alter our immune system.

For example, pollen grains may cause allergic responses such as inflammation and thus produce chronic immunological problems.

Basically, what occurs in the countercurrent multiplier process? basically, what occurs in the countercurrent multiplier process
Anit [1.1K]
The answer is the last one. Countercurrent multiplication in the kidneys is the way toward utilizing vitality to create an osmotic slope that empowers you to reabsorb water from the tubular liquid and deliver concentrated pee. It is discovered broadly in nature and particularly in mammalian organs. 
Countercurrent multiplication was initially considered as a system whereby pee is gathered in the nephron. At first, concentrated in the 1950s by Gottschalk and Mylle following Werner Kuhn's hypotheses, this instrument picked up notoriety simply after a progression of confounded micropuncture tests.

Calculate the volume of 1 M NaOH needed to prepare 12.0 mL of a 0.10-M solution. Prepare this solution. (Refer to the Dilutions
Lapatulllka [165]

Answer:

1.2 mL

Explanation:

<em>This is a problem of simple dilution. The dilution principle simply agrees that the number of moles before dilution must be equal to the number of moles after dilution.</em>

Recall that: number of moles = mass/molar mass or molarity x volume.

Hence, for the dilution principle:

              initial molarity x initial volume = final molarity x final volume.

In this case, initial molarity of NaOH = 1 M, initial volume = ?, final molarity = 0.1 M, final volume = 12.0 mL.

Initial volume = final molarity x final volume/initial molarity

                       = 0.1 x 12/1 = 1.2 mL

It thus means that 1.2 mL of 1 M NaOH would be taken and then diluted up to 12.0 mL mark by the addition of distilled water in order to produce 12.0 mL, 0.10 M NaOH solution.
