Step-by-step explanation:

esy

Because planets more massive than Earth would retain significantly more internal heat from their initial formation, and because heat drives plate tectonics (via the conveyor belt of sinking and rising rock within the mantle), plate activity should be prolonged on such planets.

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.
