a sample of oxygen collected over water at a temperature of 18.0∘c exerts a pressure of 670. torr. what is the dry gas pressure of the oxygen? (the vapor pressure of water at 18.0∘c is 15.5 torr.)

Answers

Answer 1

The dry gas pressure of the oxygen is 654.5 torr.

To find the dry gas pressure of the oxygen, we need to subtract the vapor pressure of water at the given temperature from the total pressure exerted by the sample.

Given:

Pressure of the oxygen collected over water = 670. torr

Vapor pressure of water at 18.0°C = 15.5 torr

Dry gas pressure of oxygen = Total pressure - Vapor pressure of water

Dry gas pressure of oxygen = 670. torr - 15.5 torr

Dry gas pressure of oxygen = 654.5 torr

Therefore, the dry gas pressure of the oxygen is 654.5 torr.

Write a balanced chemical equation for the reaction of solid vanadium(V) oxide with hydrogen gas to form solid vanadium(III) oxide and liquid water.

Answers

V₂O₅ (s) + 2H₂ (g) → V₂O₃ (s) + 2H₂O(l) is the balanced chemical equation for the reaction of solid vanadium(V) oxide with hydrogen gas to form solid vanadium(III) oxide and liquid water.

What is Balanced Chemical Equation ?

The balanced chemical equation is the equation in which the number of atoms on the reactant side is equal to the number of atoms on the product side in an equation.

The word based equation is

Vanadium(V) oxide + Hydrogen gas → Vanadium (III) oxide + Water

Now write the chemical equation

V₂O₅ (s) + 2H₂ (g) → V₂O₃ (s) + 2H₂O(l)

Reactant side                Product side

V = 2                                V = 2

O = 5                                O = 5

H = 4                                 H = 4

We can see that the number of atoms on reactant side is equal to the number of atoms on product side. So the given equation is balanced.

Thus from the above conclusion we can say that V₂O₅ (s) + 2H₂ (g) → V₂O₃ (s) + 2H₂O(l) is the balanced chemical equation for the reaction of solid vanadium(V) oxide with hydrogen gas to form solid vanadium(III) oxide and liquid water.

The molecular formula of rose oxide:

The formula of rose oxide will be [tex]C_{10}H_{18}O[/tex].

What is the molecular formula?

An expression known as the molecular formula describes how many atoms of each element are present in a single compound's molecule. It shows the exact number of atoms in every molecule.

Use the rule of thirteen to obtain the molecular formula for a chemical whose molecular mass is known. Follow these procedures to obtain the molecular formula:

To get the fundamental formula, multiply the molar mass by 13. (sum of the masses of one carbon atom and one hydrogen atom)

Molecular mass/ 13 = n + r/13

where, n = numerator and r = remainder

Base formula is [tex]C_{n}H_{n+r}[/tex]

Calculation:

Remove the mass of the carbon and hydrogen compound that belongs to the same group as the additional atoms if the molecular formula contains atoms in addition to carbon and hydrogen.

Molecular mass /13 = 154/13

= 11 x 13 = 143      

Thus, 11 non-H atoms are 11C.

Thus, the formula is  [tex]C_{11}H_{11+11} = C_{11}H_{22}[/tex]

If oxygen, is present then the mass is 16 and remove [tex]CH_{4}[/tex].

[tex]C_{11}H_{22} - CH_{4} + O = C_{10}H_{18}O[/tex]

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]

n2= 0.600 moles

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:

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.

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.

% V/V = (mL solute/mL solution) × 100% =

% V/V = (85 mL/180 mL) × 100% = 47% V/V

What is surface tension? what is the relationship between intermolecular forces and surface tension? how does surface tension change with temperature?

Answers

Because of its molecule's cohesive nature, surface tension has the quality to resist an external force.

Surface tension is simply a property of the surface of a liquid that allows it to resist an external force.

If the intermolecular forces are stronger further results in higher surface tension. For example; water has a high surface tension resulting in strong dipole intermolecular forces. Another example is oil. Oil has a low surface tension resulting in lower dipole intermolecular forces.

Temperature is inversely proportional to Surface tension. Therefore, surface tension increases as the temperature decreases.
