Which equation has infinitely many solutions? A. -9x- 9(-x- 10) = 90
B.7(-x + 4) = 90- 7x
C.-7(-x + 4) = 90- 7x
D.-2x- 7(-x + 4) = 90

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.
