The lighter components are able to rise higher in the column before they are cooled to their condensing temperature, allowing them to be removed at slightly higher levels.
I hope this helps

Answer:
<h2>Ionic</h2><h3>
Evidence: It can be proved by a simple experiment, sand doesn't dissolve in water but NaCl (table salt) does. (excluding cases like BaSO4 and sugar and amino acids)</h3>
Cause: The electrostatic bonds among ions in a lattice only hold them together like two magnets with unlike poles facing each other. The water molecules can split them through the similar process with several molecules ganging up on them, the H+ parts of the molecules attracts the anion and O2- part; the cations. If this electrostatic attraction is big enough, the bonds between the solid's ions break (into separate ions). And so the solid dissolves. This is usually the case with most.
Why not covalent structures?: Sure, covalent solids have a low m.p and b.p for low inter<em>molecular </em>forces, the covalent bonds here are strong and cannot easily be 'pulled apart' by water molecules. They usually have stronger inter<em>molecular </em>forces than that of water.
But... if their inter<em>molecular </em>forces are weaker or similar, sure they can dissolve easily. Like any often-used alcohol (glacial).
The net force is 15 and the box moves to the right
Answer:
The answer to your question is 200 g
Explanation:
Data
mass of water = ?
mass of NaOH = 4 g
concentration = 2 %
Formula
% mass = mass of solute/mass of solution x 100
-Solve for mass of solution
mass of solution = mass of solute / % mass x 100
-Substitution
mass of solution = 4 / 2 x 100
-Simplification
mass of solution = 2 x 100
-Result
mass of solution = 200 g
