What is the measure of WV?

A.) 21
B.) 42
C.) 84
D.) 104

arc WV = 84 degrees

Step-by-step explanation:

Here, we want to get the length of the arc wv

We can use the angle arc relationship here

From what we have here, the value of the arc wv is the product of 2 and the angle facing it

Thus, we have it that;

Arc WV = 2 * angle WXV

arc WV = 2 * 42 = 84 degrees

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.
