Susan put all her crayons in a container. of the 160 crayons in the container, 25% of them are red, 45% are blue, 10% are yellow, and 20% are orange which proportion can be use to find the total number of blue (b) crayons?

72

Step-by-step explanation:

cause you times 160x.45 you get 72

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.
