Polly has a certain number of dollar bills in her purse and no change. she spends half the
money on a scarf and gives $1 to a homeless person outside the store. she spends half the
remaining dollars for lunch and tips the waiter $2. she then spends half of what she has
left for a cd, and just before she goes home she spends $3 on a smoothie. she has $1
left. how many dollars did she begin with?

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.
