PLEASE HELP I DON'T KNOW THIS IT IS SO HARD??
I will give brainliest to the CORRECT ANSWER :(

D

Step-by-step explanation:

Hey There!

So the first thing we want to do is find the volume for a rectangular prism

volume = height x length x width

so to find the volume of this prism we do

If you plug that into a calculator you get that the volume of the prism is 1 1/2

Now we want to find how many half unit cubes there are

It says that there are 8 half unit cubes in every unit cube

So to find the amount of half cubes we multiply 8 by 1 1/2

=12

So we can conclude that the answer to this problem is D

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.

by definition, an arc subtended by a central angle of some given measure has the same measure. so .
