Solve equatiob using the subtractiob and addition properties of equality
6a -3 = -7a, a=3/13

Step-by-step explanation:

6a-3=-7a

6a-(-7a)=3

6a+7a=3

13a=3

a=3/13

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.
