Hello, HELP PLS PLS PLS

The answer would be B.

Step-by-step explanation:

1:?

4:12

?:27

If 4:12 is a ratio of 1:3 then we can assume that the other unknown numbers also use this same ratio. So the ratio for 1:? would be 1:3 and the ratio for ?:27 would be 9:27 bringing you back to the original ratio of 1:3

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.
