Help please, i'm trying to get all my work done as report cards come out today!

1. -7

Step-by-step explanation:

-3x - 5 = 16

add 5 to both sides of the equation.

-3x = 16

divide both sides by -3

x = -7

(Sorry, I don't know what 2 is!)

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.
