Which of the following apply to a solution’s concentration.
all that
the physical properties of a solution are not affected by the concentration of the components.
boiling points and freezing points of solutions change as the concentration of the solute changes.
moles of solute = (liters of solution) x (molarity of solution)
(initial concentration)(initial volume) = (final concentration) (final volume)
concentration affects if an acid is weak or strong.

All of them apply according to the exam your are on because they all need concentration to work up the certain chemical

Explanation

The physical properties of a solution are not affected by the concentration of the components.

Boiling points and freezing points of solutions change as the concentration of the solute changes.

Moles of solute = (Liters of solution) x (Molarity of solution)

(Initial Concentration)(Initial Volume) = (Final Concentration) (Final Volume)

Concentration affects if an acid is weak or strong.

explanation:

venn diagram is pictorial representation with of circles showing the relation between two finite sets or things. the intersection part of two circles conveys the relation present in between those sets or things.

here in the venn diagram of sand and salt two circles represent sand and salt. but the area falling under the intersection of these circle represents the mixture of sand and salt.

so, in a venn diagram the mixture will be placed in a middle that is in between the intersection of two circles.
