calculate the change in entropy that occurs in the system when 35.0 gg of isopropyl alcohol condenses from a gas to a liquid at the normal boiling point of isopropyl alcohol (82.30∘C,ΔHvap=39.9kJ/mol)(82.30∘C,ΔHvap=39.9kJ/mol).
Express your answer in joules per kelvin to three significant figures.

Answers

Answer 1

The change in the entropy which will occurs in the system when the 35.0 g of the isopropyl alcohol and condenses from the gas to the liquid is 65.4 JK⁻¹.

The entropy change is as :

ΔS = Q / T

Where,

Q is the total heat energy :

Q = n ΔH

Where,

n is the number of moles

ΔH is the enthalpy of vaporization

The mass of the isopropyl alcohol = 35 g

The moles of the isopropyl alcohol = mass / molar mass

The moles of the isopropyl alcohol = 35 / 60

The moles of the isopropyl alcohol = 0.583 mol

The entropy change = (39.9 × 10³ × 0.583) / 82.30 + 273

The entropy change = 65.4 JK⁻¹

how the molecule’s properties affect the physical properties of a molecule

Answers

The intermolecular forces, such as hydrogen bonds or van der Waals attractions, which draw one molecule to its neighbors, govern a substance's physical properties. Due to the relatively weak intermolecular forces of attraction, molecular substances typically take the form of gases, liquids, or low melting point solids.

How do the intermolecular forces affect physical properties?

The forces that bind two molecules together are known as intermolecular forces. Intermolecular forces have an impact on physical properties. Strong and weak forces both exist; the stronger the force, the more energy is needed to separate the molecules from one another. As intermolecular forces increase melting, boiling, and freezing points rise.

The following intermolecular forces are listed in order of strength:

Van der Waals dispersion forcesVan der Waals dipole-dipole interactionsHydrogen bondingIonic bonds

It would take very little energy to separate two molecules if they are connected by van der Waals dispersion forces. On the other hand, it requires a lot more energy to separate two molecules that are joined together by ionic bonds.

In a certain reaction, 27.3 g of iron reacts with 45.8 g of oxygen. What is the limiting reactant?

Answers

The limiting reactant for the reaction between 27.3 g of iron and 45.8 g of oxygen is iron

Balanced equation

We'll begin by writing the balanced equation for the reaction between iron and oxygen. This is given below:

4Fe + 3O₂ --> 2Fe₂O₃

Molar mass of Fe = 56 g/mol

Mass of Fe from the balanced equation = 4 × 56 = 224 g

Molar mass of O₂ = 16 × 2 = 32 g/mol

Mass of O₂ from the balanced equation = 3 × 32 = 96 g

SUMMARY

From the balanced equation above,

224 g of Fe reacted with 96 g of O₂

How to determine the limiting reactant

The limiting reactant can be obtain as illustrated below:

From the balanced equation above,

224 g of Fe reacted with 96 g of O₂

Therefore,

27.3 g of Fe will react with = (27.3 × 96) / 224 = 11.7 g of O₂

From the calculation above, we can see that only 11.7 g of O₂ out of 45.8 g given is required to react completely with 27.3 g of Fe.

Thus, Fe is the limiting reactant.

What is Enthalpy of Vaporization ?

The amount of enthalpy or energy that must be added to a liquid substance into gas substance is called Enthalpy of Vaporization. It is also known as Latent heat of vaporization.

How to find the energy change from enthalpy of vaporization ?

To calculate the energy use this expression:

[tex]Q = n \Delta H_{\text{vapo.}[/tex]

where,

Q = Energy change

n = number of moles

[tex]\Delta H_{\text{Vapo.}}[/tex] = Molar enthalpy of vaporization

Now find the number of moles

Number of moles (n) = [tex]\frac{\text{Given Mass}}{\text{Molar mass}}[/tex]

                                   = [tex]\frac{80.2\ g }{159.8\ g/mol}[/tex]

                                   = 0.5 mol

Now put the values in above formula we get

[tex]Q = - n \Delta H_{\text{vapo.}[/tex]         [Negative sign is used because Br₂ condensed here]

   = - (0.5 mol × 15.4 kJ/mol)

D. An atom with 8 protons and 8 neutrons.

Answers

Considering the definition of ion, an atom with 11 protons and 9 electrons (option A) is an ion since the number of electrons is less than the number of protons, acquiring a positive charge.

What is an ion

An ion is an electrically charged particle that is made up of an atom or molecule that is not electrically neutral, that is, that in its constitution has gained or lost electrons.

In other words, an ion is a molecule or atom that has a positive or negative electrical charge. That is, an ion is an atom whose electrical charge is not neutral.

On the other hand, an atom is made up of a nucleus made up of protons (positively charged) and neutrons (neutrally charged), around which electrons (negatively charged) orbit.

An atom has as many protons as electrons, so the total charge is zero and it is globally neutral.

The loss or gain of electrons allows the atom to acquire an electrical charge, transforming itself into an ion. If the electrical charge is positive, it is called a cation; if it is negative, it is called an anion.

An atom with 11 protons and 9 electrons (option A) is an ion since the number of electrons is less than the number of protons, acquiring a positive charge.

A sample of 0.400 moles of nitrogen occupies 0.800 L. Under the same conditions, what number of moles occupies 1.200 L

Answers

Taking into account the Avogadro's Law, 0.600 moles occupies 1.200 L.

Avogadro's Law

Avogadro's Law is a gas law that relates the volume and amount of gas at constant pressure and temperature.

Avogadro's law states that volume is directly proportional to the amount of gas: increasing the amount of gas will increase the volume, while decreasing the amount of gas will decrease the volume.

Mathematically, this law states that the ratio between the volume and the amount of gas is constant:

[tex]\frac{V}{n} =k[/tex]

Assuming that there is a certain amount of gas n1 that occupies a volume V1 at the beginning of the experiment, by varying the amount of gas to a new value n2, then the volume will change to V2, and the following is true:

[tex]\frac{V1}{n1} =\frac{V2}{n2}[/tex]

Amount of moles in this case

In this case, you know:

V1=0.800 Ln1= 0.400 molesV2= 1.200 Ln2= ?

Replacing in Avogadro's Law:

[tex]\frac{0.800 L}{0.400 moles} =\frac{1.200 L}{n2}[/tex]

Solving:

[tex]n2x\frac{0.800 L}{0.400 moles} =1.200 L[/tex]

[tex]n2=\frac{1.200 L}{\frac{0.800 L}{0.400 moles} }[/tex]
