THREE expressions equivalent to –81x+27.

Hey there!

One thing we can do to get an equivalent expression is to divide both sides by 3. That would get us . If we simplify this, we get .

Another thing we can do is divide both sides by 27, because it is divisible by 27. That would get us . If we simplify this, we get .

One last thing we can do is multiply it by 1, and add zero, because that does not change it at all. That would give us .

Have a terrificly amazing day! :D

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.
