How many quarts of pure antifreeze must be added to 6 quarts of a 30% antifreeze solution to obtain a 50% antifreeze solution

answer:

the position of equilibrium will shift to the left.

step-by-step explanation:

the general equation for the dissociation of a weak base is

b + h₂o   ⇌   bh⁺ + oh⁻

according to le châtelier's principle, when a stress is applied to a system at equilibrium, the system will respond in a way that tends to relieve the stress.

if you apply a stress by adding more bh⁺ or oh⁻,   the system will respond by moving in a direction that gets rid of the added ions.

the position of equilibrium will shift to the left, forming more of the undissociated base.

the expression (1.26)2t reveals the approximate rate of increases in the number of plants semiannually.

hope this : )

the first option is the answer.
