How many moles of O2 were produced in a decomposition reaction of H2O2 if the pressure was 0.978 atm, the temperature was 27C and the volume of O2 gas collected was 0.082L

Answers

The number of mole of O₂ produced from the decomposition of H₂O₂ is 0.0033 mole

How to determine the number of mole of O₂ produced

We'll begin by obtaining the mole of H₂O₂ that decomposed. This is obatined as follow:

Pressure (P) = 0.978 atmTemperature (T) = 27 °C = 27 + 273 = 300 KVolume (V) = 0.082 LGas constant (R) = 0.0821 atm.L/Kmol Mole of H₂O₂ (n) =?

PV = nRT

Divide both sides by RT

n = PV / RT

n = (0.978 × 0.082) / (0.0821 × 300)

n = 0.0033 mole

Finally, we shall determine the number of mole of O₂ produced. This is illustrated below

H₂O₂ -> H₂ + O₂

From the balanced equation above,

1 mole of H₂O₂ decomposed to produce 1 moles of O₂

Therefore,

0.0033 mole of H₂O₂ will also decompose to produce = 0.0033 mole of O₂

Thus, number of mole of O₂ produced from the reaction is 0.0033 mole

Taking into account the definition of Avogadro's Number and molar mass, the mass of 4.23×10²⁴ molecules of oxygen is 112.37 grams.

Definition of Avogadro's Number

Avogadro's Number  is called the number of particles that make up a substance (usually atoms or molecules). This can be found in the amount of one mole of said substance and its value is 6.023×10²³ particles per mole.

Avogadro's number applies to any substance.

Definition of molar mass

The molar mass of substance is a property defined as its mass per unit quantity of substance, in other words, molar mass is the amount of mass that a substance contains in one mole.

Mass of 4.23×10²⁴ molecules of oxygen

You can apply the following rule of three: if 6.023×10²³ molecules are contained in 1 mole of oxygen, then 4.23×10²⁴ molecules are contained in how many moles of oxygen?

amount of moles of oxygen= (4.23×10²⁴ molecules × 1 mole)÷ 6.023×10²³ atoms

amount of moles of oxygen= 7.023 moles

7.023 moles of oxygen are 4.23×10²⁴ molecules of oxygen.

Being 16 g/mole the molar mass of oxygen, the mass of oxygen in 7.023 moles is calculated as:

mass of oxygen= 7.023 moles×16 g/mole

mass of oxygen= 112.37 grams

Finally, a mass of 112.37 grams are present in 4.23×10²⁴ molecules of oxygen.

A small but important difference between 3s, 3p, and 3d are due mainly to the Heisenberg uncertainty principle. Their principal quantum number ones rule and the number of weapons that can hold the penetration effect.

An electron in the 3s orbital is more likely to be close to the nucleus than is an electron in the 3p orbital; an electron in the 3p orbital, in turn, has a greater probability of being close to the nucleus than does one in the 3d orbital.

Therefore, degenerate orbitals are those orbitals that have the same energy. As given in the above representation, 2s and 2p orbitals are degenerate; 3s, 3p and 3d orbitals are degenerate, and so on. The degeneracy of the orbitals breaks down in the case of multi-electron systems.

When 0.1 mol of PCls (g) is heated at 78.5 °C in a 1.00 L container, the pressure at
equilibrium is 3.50 x 105 Nm2. Calculate the degree of dissociation of PCIs.

Answers

Based on the pressure of the gas in the 1.00 L container, the percentage dissociation of PCl₅ is 60%.

What is the equation of the dissociation of PCl₅?

The equation of the dissociation of PCl₅ when heated is given below:

PCl₅ (s) ---> PCl₃ (g) + Cl₂ (g)

Based on the equation of the dissociation of PCl₅, 1 mole of PCl₅ decomposes to give 1 mole of PCl₃ gas and 1 mole of Cl₂ gas.

Hence, 1 mole of PCl₅ dissociates to give 2 moles of gas.

0.1 mole of PCl₅ will dissociate to give 0.1 * 2 moles of gas = 0.2 moles of gas.

At STP, the pressure of 0.2 moles of gas is calculated as follows:

PV = nRT

where;

P is pressure = ?V is volume = 1.00 Ln is the number of moles = 0.2R is molar gas constant = 0.082 L.atm/k.molT is temperature = (273 + 78.5) K

P = nRT / V

P = 0.2 * 0.082 * 351.5/ 1

P = 5.76 atm or 5.84 * 10⁵ N/m²

Percentage dissociation of PCl₅ = (3.50  * 10⁵/5.84 * 10⁵) * 100%

The physical property that allows iron to be easily separated from most other materials is magnetism.

Metals that naturally attract magnets are known as ferromagnetic metals. These magnets tend to firmly stick to these metals. For example when you rub a piece of iron along a magnet the north seeking poles of the atoms get lined up in one direction. This causes a force to build up a force and this force creates a magnetic field. This is how a piece of iron becomes a magnet.

A student that is sheltering in place during the COVID-19 pandemic, was told to test three
different colors of markers. The student placed three different colors on a sheet of
chromatography paper, as shown in the diagram. The student also tested a different color of
marker, labeled the “unknown” to determine if the color marker was made from other colors.
The student prepares the experimental setup by using chromatography paper (a polar material)
and putting the paper in a nonpolar solvent. The results of the experiment (the “developed
chromatograms” are shown on the right.
(1) Which color of marker is the least polar? Justify your answers in terms of the IMF
interactions between the color dyes and the solvent or between the color dyes and the
paper.
(2) Which dye(s) is/are present in the unknown sample? Justify your answer.
(3) What was the most likely color of marker that the student tested?

Answers

The color of marker that is the least polar is the red dye because it shows the least interaction with the polar chromatography paper and the most interaction with the non-polar solvent.

The dyes that are most likely in the unknown sample are the blue and yellow dyes because the two spots produced by the unknown sample traveled almost the same distance as the blue and yellow dyes.

The most likely color of marker that the student tested is yellow.

What is chromatography?

Chromatography is a separation technique used to separate colored substances by means of their interactions with mobile solvent phase and a non-mobile solid phase.

The dye that has the most interaction with the solvent phase will travel farther in the chromatographic column whereas the dye that has the least interaction with the solvent will travel the least distance.
