Figure abcd is a parallelogram. two trapezoids are created using line segment xy such that ax ≅ cy.
what is true about the areas of the trapezoids?

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.

4/6 = 2/3

so it should take 3/3 hours per man. so 9 hours is the answer 3*3 =9
