A12-foot by 15-foot patio is increased by placing a stone border around the patio. the width of the border is the same all the way around the patio. the perimeter of the patio is extended by 74 feet. the equation which represents x, the width of the border is 2[(12+2x)+(15+2x)]=74

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.
