Which expression is equivalent to |a| ≤ 4 A. a ≤ -4 or a ≥ 4

B. a ≥ -4 or a ≤ 4

C. a ≥ -4 and a ≤ 4

D. a ≤ -4 and a ≥ 4

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.
