Answer:The top of the fractional distillation column will have a more volatile liquid as compared to the liquid at the bottom.
Explanation:
Fractional distillation is the method of separating liquids with different boiling points.For example,ethanol can be separated from water from a ethanol-water mixture.The component with a lower boiling point will pass in the column and collected first followed by higher boiling point component.Repeated vaporization and condensation results in the separation of the components in the mixture.
Answer:
Using the sprayer on your sink if you have one
Explanation:
If a chemical gets into your eye, you will need to flush the eye thoroughly with water in order to get the chemical out of the eye before it causes any kind of damage to the eye.
This could normally be done in an eye wash station. However in the absence of an eye wash station, one could use the sprayer of the sink if he/she has one. This will deliver water to completely flush the eye at lower pressure.

What types of atoms typically form covalent bonds?
The correct answer:
d) Nonmetals with nonmetals, because their difference in electronegativity is below 1.7.
En example to explain:
An example of a covalent bonding: HCl -> 2 nonmentals
-> a difference in electronegativity less than 1.7:
EN(Cl) = 3.0 and EN (H) = 2.1 (you can search these values in a periodic table)
/\EN = 3.0 - 2.1 = 0.9
0.9 < 1.7
I hope this helped you out!
