The answer is NH4Cl!
Ionic bonding=cation + anion
- the cation ammonium (NH4) has a single electron in its valence shell, and Chlorine needs a single electron to fill its valence shell, and they stick together.
Covalent bond= involves the sharing of electron pairs between atoms
- present in Ammonium ion between Nitrogen and Hydrogen atoms
The best design for this experiment is to number the items from 1 to 1,200 and then choose random numbers in the table of random digits (second option).
<h3>How to use a table of random digits?</h3>
These tables are used to randomly assign items or subjects into groups when experimenting. The best way to use these tables are:
- Give each item or participant a number.
- Take a lot at the table and choose a number.
- If this number is the same that the number assigned to an item or participant classify it in the first group.
- Keep selecting.
Based on this, for this experiment the steps are:
- Number the items from 1 to 1,200.
- Identify numvers in the table.
- Assign the first 400 items to the process 1 group.
- Repeat the process for the other two groups.

Answer:
Powerade has the most dissolved ions, followed by Gatorade and lastly vitamin water
Explanation:
How conductive a certain solution is, is based on the kind of ions that are present or dissolved in the solution. Hence, we have it that, the higher the concentration of the ions that are present in a solution, the better it will conduct.
There is thus, a direct relationship between what is dissolved or the kind of present ions and how conductive the solution is.
A solution with more dissolved ions is a better conductor of electricity and thus has a conductivity value that is higher
Thus, we can conclude that Powerade has more dissolved ions, Gatorade has less and Vitamin water has the least
