Which expression has a value that is greater than 42.537? A: (4×10)+(2×1)+(5× 1/10) +(9x100)+ (3x1/1000)
B: (4×10)+(1×1)+(6×1/10) + (9x 1/100) + (5x 1/1000)
C: (4×10)+(2×1)+(5×1/10) + (3x1/100) + (7x1/1000)
D: (4×10)+(2×1)+(5×1/10) + (1x1/100) + 9x1/1000)

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.
