Answer:
B. CH₄
Explanation:
The primary rule in deciding solubilities is, Like dissolves like. That is,
- A polar solute dissolves in a polar solvent.
- A nonpolar solute dissolves in a nonpolar solvent.
C₆H₁₄ is a nonpolar solvent. Its strongest intermolecular forces are London dispersion forces.
CH₄ is a nonpolar solute. It contains only nonpolar C-H bonds, and its strongest intermolecular forces are London dispersion forces.
Molecules of the two compounds can easily intermingle with each other because the attractive forces between them are so small.
A is wrong. H₂O is a highly polar substance. Its molecules are so strongly attracted to each other that they will not dissolve in the C₆H₁₄.
C and D are wrong. Both NaCl and SnS are compounds of a metal and a nonmetal. We would predict them to be ionic solids, at the extreme end of polarity. They will not dissolve in C₆H₁₄.
The reaction is not at equilibrium because Q >P hence the reaction moves towards the left hand side.
<h3>What is the equilibrium constant?</h3>
The equilibrium constant is a figure that tells us the extent to which the reactants have been converted to products in a reaction.
Now we have the reaction; PCl3(g) + Cl2(g) ⇄ PCl5(g) hence we can write;
Q = [PCl5]/[PCl3] [Cl2]
Q = 0.39/0.21 * 0.41
Q = 4.5
The reaction is not at equilibrium because Q >P hence the reaction moves towards the left hand side.

Answer:
The answer to your question is 175 gallons
Explanation:
Data
60% antifreeze solution volume = ? = x
25% antifreeze solution volume = 25%
Final concentration 50%
Process
0.6x + 0.25(70) = 0.5(70 + x)
Simplification
0.6x + 17.5 = 35 + 0.5x
0.6x - 0.5x = 35 - 17.5
0.1x = 17.5
x = 17.5/0.1
Result
x = 175 gallons
