The sum of angle measures of a quadrilateral is 360?

Step-by-step explanation:

sum of angle in a polygon =

(n - 2)180

Where n = 4

Sum of angle in quadrilateral =

(4 - 2)180

= 2 × 180

= 360°

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.
