Chemistry

Answer:

2M

Explanation:

Given parameters:

Number of moles of FeCl₃  = 0.3 moles

Volume of water  = 150mL

Unknown:

Molarity of solution = ?

Solution:

The molarity of a solution is the number of moles of solutes in a given solution. It is one of the ways of expressing concentration. The unit is always M i.e mol/dm³.

              Molarity  = \frac{number of moles }{volume}

Express the volume in dm³;

                 150mL gives 0.15dm³

               Molarity  = \frac{0.3}{0.15}

                                = 2M

Do you think there is a time when we will run out of fossil fuels to burn. why or why not?
Sedaia [141]

Yes, there will definitely be a time when we run out of fossil fuels to burn. It's often claimed that we have enough coal to last hundreds of years. But if we step up production to fill the gap left through depleting our oil and gas reserves, the coal deposits we know about will run out in 2088.

create visual representations that show the interactions between the particles in both samples during vaporization
ivolga24 [154]

Given what we know, we can confirm that despite not being able to provide a visual representation, if you were to create one, it would show the atoms in the substance moving with <u>more and more </u>energy over time until vaporization occurred.

<h3>What is vaporization?</h3>
  • Vaporization is the changing of a liquid into a gas.
  • This is known as a phase change.
  • This happens when the atoms receive enough heat energy.
  • The heat energy provides the atoms with kinetic energy and causes them to move faster over time.
  • When the kinetic energy is enough to rupture the bonds that hold a liquid together, it becomes a gas.

Therefore, given that vaporization is when atoms within a substance gain so much kinetic energy that they are able to rupture the bonds that hold them relatively close together and change into a gas, we can confirm that a visual representation would have to be a diagram showing the increased movement of atoms over time.

The half life of a certain radioactive element is 1,250 years what percent of the atoms remain after 7500 years
andrezito [222]
Each half-life results in ~50% (1/2) of the original element remaining.

7500/1250 = 6 half-lives, so 100(1/2)^6
= 100(0.015625)
= 1.5625% of the original element would remain
