Sive up Annette is standing with a tree directly between her and a building. She stands so

that, in her eyes, the top of the tree appears to "touch" the top of the building. If the

distance between her and the tree 30 ft, the distance between the tree and the

building is 15 ft, and the tree is 20 ft tall, how tall is the building? (You may ignore

her height.)

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.
