In ten years the average number of hours of TV watched per week dropped from 23.9 to 21.4. Find the percent of change. Round to the nearest tenth of a percent

I think its 10.5

Step-by-step explanation:

Find the number in the tenth place

1 and look one place to the right for the rounding digit 0. Round up if this number is greater than or equal to

5 and round down if it is less than

5.0.1

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.
