Find the solutions to x2 = 27.
O A. x = +3,5
B. x = +39
O C. x = +9.12
D. X = +9.5

A

Step-by-step explanation:

Given

x² = 27 ( take the square root of both sides )

x = ±

  = ±

  = ± ×

  = ± 3 → A

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.
