Mike wants to purchase a wall unit, but he needs to determine the volume before buying it. If the wall unit is 3 feet deep, what is the volume of this wall unit?

The correct answer is 27 cubic feet.

Step-by-step explanation:

Mike wants to purchase a cubical wall unit.

But before buying the unit, Mike wants to find the volume of this wall unit.

Dimension of the wall unit is 3 feet.

Volume of a cube is given by where a is the length of the side.

Therefore volume of the cubical wall unit is = 27 cubic feet.

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.
