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 10⁵ or 100,000 times more acidic than hand soap.

Find the mean, median, and mode of the following list of values. Round to the nearest tenth if necessary.

grin007 [14]

Answer:

D.

Mean: 24.8

Median: 26

Mode: 26

Explanation:

The mean is the average. To find the average, add up all the numbers and divide by the amount of numbers there are.

30 + 26 + 25 + 11 + 34 + 20 + 26 + 26 = 198

Now, we divide by how many numbers we started out with (8).

198 divided by 8 = 24.75, rounded would be 24.8

To find the median, you arrange the numbers from smallest to largest, and find the middle number like this:

11, 20, 25, 26, 26, 26, 30, 34

As you can see, the middle number is 26.

To find the mode, you arrange the number from smallest to largest, and find the number that appears more often.

11, 20, 25, 26, 26, 26, 30, 34

As you can see, the number 26 appears the most often.

So, we end up with:

Mean: 24.8

Median: 26

Mode: 26

QUESTION 50 Cohesion, surface tension, and adhesion are the properties of water molecules that

snow_lady [41]

Answer:

enable capillarity

Explanation:

It is well known that water tends to adhere to the walls of the vessel in which it is contained. This is due to the force of adhesion which is defined as the force of attraction between unlike molecules. Cohesion is defined as the force of attraction between like molecules. In the case of a plant, cohesion of water molecules in the xylem vessels prevents the water column from breaking. The forces of adhesion, surface tension and cohesion are the basis of capillarity,that is, the rise of liquids in capillary tubes.
