Barb loves ice cream candy bars and wants to share 7/8 of them with her friends. If she gives one to each of her 21 friends, how many candy bars will she need before starting to share?

24

Step-by-step explanation:

21 times 8 is 168, and 168 divided by 7 is 24, therefore she would need 24 to give among 21 friends if she still wanted to have 1/8 left over.

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.
