Can you help work question number 4 please?

Step-by-step explanation:

if 2 sides are equal which means it is an Isosceles triangle

so,

→ 52 + 52 + c = 180

→ 104 + c = 180

→ c = 180 - 104

→ c = 76°

d = 52°

hope this answer helps you dear! take care and may u have a great day!

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.
