Where would you find a strong acid on the pH scale?<br> A. 1<br> B. 5<br> C. 3 <br> D. 13

aivan3 [116]

Answer:

A. 1

Explanation:

pH is a measure of how acidic/basic a substance is. The range goes from 0 - 14, with 7 being neutral. pHs of less than 7 indicate acidity, whereas a pH of greater than 7 indicates a base.

note: the closer you are to the neutral the weaker it gets.

Converting the temperature to Kelvin,

You measure the pH of your backyard soil and find it is 7. You measure the pH of your friend's backyard soil and find it is 4. H

Answer:

1000 times.

Explanation:

Hello,

In this case, since the pH is defined by:

$pH=-log([H^+])$

If we want to compute the concentration of hydrogen we must write:

$[H^+]=10^{-pH}$

Thus, for both the backyard soils we compute:

$[H^+]_{pH=7}=10^{-7}=1x10^{-7}M$

$[H^+]_{pH=4}=10^{-4}=1x10^{-4}M$

It means that:

$\frac{[H^+]_{pH=4}}{[H^+]_{pH=7}} =\frac{1x10^{-4}M}{1x10^{-7}M}\\ \\\frac{[H^+]_{pH=4}}{[H^+]_{pH=7}}=1000$

It means that the concentration of hydrogen at a pH of 4 is 1000 times greater than the concentration of hydrogen at a pH of 7.

Regards.

During metaphase, the chromosomes are ______.

lesya692 [45]

Answer:

During metaphase, the cell's chromosomes align themselves in the middle of the cell through a type of cellular "tug of war." The chromosomes, which have been replicated and remain joined at a central point called the centromere, are called sister chromatids.
