Answer:d
Explanation: over time water evaporates which leaves you with the white crystals mass
<span>The Atomic Model was something that was first developed by Neils Bohr. Several years later, Schrodinger took Bohr's basis of a theory and developed it into something larger. So as we can see, theories are a bit like puzzles. When first starting out, one person develops something, or has an idea on something. Others trying to either prove or disprove the original findings, will then test things in a new way, revealing more and more of the puzzle. As the puzzle becomes more and more clear, there is more and more that is revealed. Eventually, we get to a point where we have almost the entire picture, however we are still missing a few key pieces that complete the puzzle. We can see the big picture, but you can not exactly prove out what exactly the details are. This is how scientists such as Bohr and Schrodinger use each others research to build and refine theories. Eventually, we reach a point where we are only missing maybe one or two pieces, and at that point, a theory transitions into almost fact, such as evolution.</span>
Answer : The equilibrium concentration of
at
is,
.
Solution : Given,
Equilibrium constant, 
Initial concentration of
= 0.260 m
Let, the 'x' mol/L of
are formed and at same time 'x' mol/L of
are also formed.
The equilibrium reaction is,

Initially 0.260 m 0 0
At equilibrium (0.260 - x) x x
The expression for equilibrium constant for a given reaction is,
![K_c=\frac{[H_3O^+][C_2H_3O_2^-]}{[HC_2H_3O_2]}](https://tex.z-dn.net/?f=K_c%3D%5Cfrac%7B%5BH_3O%5E%2B%5D%5BC_2H_3O_2%5E-%5D%7D%7B%5BHC_2H_3O_2%5D%7D)
Now put all the given values in this expression, we get

By rearranging the terms, we get the value of 'x'.

Therefore, the equilibrium concentration of
at
is,
.
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
Explanation:
<span>Liquid alcohol will change to vapor when temperature reaches the : D. Boiling point
When the temperature reach the boiling point, the molecule that held the liquid's particle together will break free and the particle will scatter.
This will cause the liquid substance to undergone a transformation into a Gaseous form</span>
