8 0

The outer core is about 1,400 miles thick, and it's made mostly of a combination (called an alloy) of iron and nickel, along with small amounts of other dense elements like gold, platinum, and uranium. These metals can, of course, be found on the surface of Earth in solid form.

2-11 Ozone molecules are constantly formed and destroyed in the atmosphere. A
evablogger [386]

Answer:

The diagram shows oxygen, O₂, which consists of two atoms of oxygen in the stratosphere, which are the two beings holding hands, forming a couple being broken up by the intense ultraviolet radiation of the Sun, such that the couple closest to the Sun are the ones that were broken into two O, atoms.

After being broken, the two beings (oxygen atoms), become free to move as they please, making them able to move faster than when they were still a couple. However, due to the likeness for their fellow beings, each of the single O beings rushed to meet the other two still coupled O₂ beings, whereby one O being rushing to meet one O₂ couple each, to form O₃ which is a new group consisting of three beings holding hands known as Ozone

Note, that O stands for atomic oxygen gas

O₂ stands for oxygen gas

O₃ stands for ozone gas

What is the percent ionization of a monoprotic weak acid solution that is 0.188 M? The acid-dissociation (or ionization) constan
djyliett [7]

Answer: The percent ionization of a monoprotic weak acid solution that is 0.188 M is 3.59\times 10^{-4}\%

Explanation:

Dissociation of weak acid is represented as:

HA\rightleftharpoons H^+A^-

 cM              0             0

c-c\alpha        c\alpha          c\alpha  

So dissociation constant will be:

K_a=\frac{(c\alpha)^{2}}{c-c\alpha}

Give c= 0.188 M and \alpha = ?

K_a=2.43\times 10^{-12}

Putting in the values we get:

2.43\times 10^{-12}=\frac{(0.188\times \alpha)^2}{(0.188-0.188\times \alpha)}

(\alpha)=3.59\times 10^{-6}=3.59\times 10^{-4}\%

Thus percent ionization of a monoprotic weak acid solution that is 0.188 M is 3.59\times 10^{-4}\%
