The density of an object is related to its mass and volume. the equation below shows the relationship between density (d),mass (m),and volume( v). which equation represents the volume of an object in relation to its density in mass?

^ this is the first question, but can you answer the other question in the picture below?

Part 1)  

Part 2)

Step-by-step explanation:

Part 1)

we know that

The density is equal to divide the mass by the volume

so

Solve for the volume v

That means------> isolate the variable v

Multiply by the volume v both sides

Divide by the density d both sides

Part 2)

we know that

The perimeter of the triangle is the sum of its three side lengths

In this problem the perimeter is equal to

so

Group terms that contain the same variable

Combine like terms

solve for w

Subtract 23 both sides

Divide by 17 both sides

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.
