PLEASE HELP Simplify by removing parentheses and, if possible, combining like terms. 12-2(6w-9) simplify your answer

- 12w + 30

Step-by-step explanation:

12 - 2(6w-9)

Expand brackets.

12 - 12w + 18

Rearrange.

- 12w + 18 + 12

Add like terms.

- 12w + 30

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.
