Rocky gets on the ride at a. the ride starts and then stops when his car is at b

30°.

Step-by-step explanation:

We know that a circle is 360°. There are 12 equal sized segments in the circle, and Rocky rides along one segment. So then you would divide 360° by 12 to get the measure of the angle, which is 30°.

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.
