Answer:Accounting for the sizes of protons, neutrons, and electrons, most of the volume of an atom—greater than 99 percent—is, in fact, empty space. ... The electrons that surround all atoms are negatively charged and cause atoms to repel one another, preventing atoms from occupying the same space.

the anwser is; B: increasing its speed
Answer:
0.321M would be the concentration of the final solution
Explanation:
In the problem, you are decreasing the concentration of a solution (The stock solution) by the addition of more solvent (This process is known as dilution).
You are increasing the volume of the solution from 15mL to 700mL, that means the solution <em>is diluted:</em>
700mL / 15mL = 46.67 times
Now, to know the concentration of a final solution we need to take the concentration of the stock solution. <em>Assuming the stock solution is 15M:</em>
15M / 46.67 =
<h3>0.321M would be the concentration of the final solution</h3>
First you have to tell people what are the choices
