Answer:

Option b. 9.59

Explanation:

First, let us calculate the pH. This is illustrated below:

[H3O+] = 3.9 x 10-5 M

pH = —Log [H3O+]

pH = —Log [3.9 x 10-5]

pH = 4.41

Recall: pH + pOH = 14

4.41 + pOH = 14

Collect like terms

pOH = 14 — 4.41

pOH = 9.59

Which statement explains how ATP and it's phosphate groups are relatedto energy that is used in plant processes
Zolol [24]

Hi my dear friend,

The statement that explain how ATP and its phosphate groups are related to energy used in plant process is that ADP gains a phosphate to create ATP, which stores energy for making sugars. These packets of energy in the form of ATP are then broken down to release energy and use that energy in synthesis of glucose.

~Thank you

GaryK [48]

Answer:

The defect of vision suffered by the person is Myopia

Explanation:

The person can't see farther objects but is able to read a book which is placed closely to the eyes, using these observations the person is suffering from MYOPIA(nearsightedness) in which observer see close objects clearly but farther objects appear blurred.

The light entering the eye isn't correctly bent, the eyeball becomes big , or the eye lens become too converging, which converges the light ray in front of the cornea

This defect can be cured by using concave lenses.

Gallium has two naturally occurring isotopes. The mass of gallium-69 is 68.9256 amu and it is 60.108% abundant. The mass of gall
NISA [10]
Hi :)
So to find the average atomic mass of gallium you need to multiply the mass and percentage of abundance in the first isotope and then add that with the mass times percentage of abundance in the second isotope. I'll show you..
First convert 60.108% into a decimal, moving the decimal point over two places to the left. 60.108% -> 0.60108. Now you can multiply it by
0.60108 * 68.9256 = 41.4298.
So now I need to do the same thing as I did for the first isotope.
39.892% -> 0.39892. <span>
0.39892 * 70.9247 = 28.29328

The last step is to add the two,</span> 28.29328 + 41.4298 = 69.72308.
So the average atomic mass of gallium is 69.723.
