In a school with only sixth and seventh graders,2/5of the 200 students are seventh graders. a. how many students in the school are seventh graders? b. describe two different ways to determine how many students in the school are sixth graders. c. of the seventh graders, 30% are in the band. if the band has the same number of sixth graders as seventh graders, what percentage of the sixth graders are in the band? explain how you found your answer.

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.

the graph line crosses the x axis at both -6 and -2, so the answer would be the second one.
