Easy question - giving and lots of points if right only need answer for b. a is already done. question attached in file.

There is no proof that the population increased by 10% every year. it is possible the first year increased by 8 the first year then 12 the next, giving a 20% increase.

Extra: the answer the the first and second year is x you must figure the x out if you want the answer to those

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.
