Due to the release of heat during its breakdown into oxygen, ozone is less thermodynamically stable than oxygen. Ozone is made up of three oxygen molecules, making it in an unstable state. In order to become stable, ozone gives up one of its oxygen molecules in order to return to its diatomic state.

Therefore, Ozone (O2) and ozone (O3) both include oxygen atoms, but they differ in terms of their physical and chemical characteristics. Ozone has a strong, pungent odor, whereas oxygen is odorless.

In the chemical equation CH4 + O2 -> CO2 + 2H2O for every one mole of carbon dioxide you produced, how many moles of water would you have?

Answers

Answer: 2 moles

Explanation:

In the balanced equation, it can be seen that everything reacts in a 1:1 mol ratio except water (H2O) as determined by the coefficient. It is simple stoichiometry, 1 mol CO2 * 2 mol H2O/1 mol CO2 = 2 mol CO2. After doing the math, the CO2 cancels out, leaving how many moles of H2O there are.

A 5.31 g sample of compound that contains only hydrogen and sulfur was combusted, and yielded 10.0 g of SO₂ and 2.81 g of H₂O. The molar mass of the compound is 68 g/mol. What is this compound's molecular formula?

Answers

The molecular formula of the compound, given that it contains only hydrogen and sulfur is H₄S₂

Hoow do I determine the molecular formula?

We'll begin by obtaining the mass of sulfur and hydrogen. This is illustrated below:

Mass of SO₂ = 10 gMolar mass of SO₂ = 64 g/mol Molar of S = 32 g/mol Mass of S =?

Mass of S = (32 / 64) × 10

Mass of S = 5 g

Mass of compound = 5.31 gMass of S = 5 gMass of H = ?

Mass of H = (mass of compound) – (mass of S)

Mass of H = 5.31 – 5

Mass of H = 0.31 g

Next, we shall determine the empirical formula

H = 0.31 gS = 5 gEmpirical formula =?

Divide by their molar mass

H = 0.31 / 1 = 0.31

S = 5 / 32 = 0.156

Divide by the smallest

H = 0.31 / 0.156 = 2

S = 0.156 / 0.156 = 1

Thus, the empirical formula is H₂S

Finally, we shall determine the molecular formula. Details below

Empirical formula = H₂SMolar mass of compound = 68 g/molMolecular formula =?

Molecular formula = empirical × n = mass number

[H₂S]n = 68

[(2×1) + 32]n = 68

34n = 68

Divide both sides by 34

n = 68 / 34

n = 2

Molecular formula = [H₂S]n

Molecular formula = [H₂S]₂

Molecular formula = H₄S₂

Calculate the concentration (M) of sodium ions in a solution made by diluting 10.0 mL of a 0.774 M solution of sodium sulfide to a total volume of 100 mL.

Answers

The concentration of sodium ions in a solution made by diluting 10.0 mL of a 0.774 M solution of sodium sulfide to a volume of 100 mL would be 0.1548 M.

Dilution

According to the dilution principle, the number of moles of solutes in a solution before and after dilution must be the same. This is expressed as the following equation:

[tex]m_1v_1 = m_2v_2[/tex]

Where [tex]m_1[/tex] is the molarity before dilution, [tex]v_1[/tex] is the volume before dilution, [tex]m_2[/tex] is the molarity after dilution, and [tex]v_2[/tex] is the volume after dilution.

In this case, [tex]m_1[/tex] = 0.774 M, [tex]v_1[/tex] = 10.0 mL, [tex]v_2[/tex] = 100 mL.

[tex]m_2[/tex] = [tex]m_1v_1/v_2[/tex]

     = 0.774 x 10/100

      = 0.0774 M

Thus, the new concentration of the sodium sulfide solution would be 0.0774 M.

Mole of the final solution: 0.0774 x 0.1 = 0.00774 mol

Sodium sulfide formula = [tex]Na_2S[/tex] ---> [tex]2Na^+ + S^{2-[/tex]

Equivalent mole of sodium ion = 0.00774 x 2

                                                    = 0.01548 mol

The concentration of sodium ions = mol/volume

                                                  = 0.01548/0.1

                                                  = 0.1548 M

In other words, the concentration of the sodium ions in the diluted solution would be 0.1548 M.

iron hydroxide decomposes to form iron oxide and water vapor. If 0.500 g of iron hydroxide are decomposed what mass of water vapor will be produced

Answers

The mass of water vapor that will be produced when iron hydroxide decomposes to form iron oxide and water vapor is 0.126 grams.

How to calculate mass?

The mass of a substance can be calculated stoichiometrically. Stoichiometry is the study and calculation of quantitative (measurable) relationships of the reactants and products in chemical reactions (chemical equations).

According to this question, iron hydroxide decomposes to form iron oxide and water vapor. If 0.500 g of iron hydroxide are decomposed, the mass of water vapor produced can be calculated as follows;

2Fe(OH)₃ → Fe₂O₃ + 3H₂O

Based on the above equation, 2 moles of iron hydroxide decomposes into 3 moles of water vapor.

moles = 0.5g ÷ 106.87 g/mol = 0.00468mol of iron hydroxide.

0.00468 × 1.5 = 0.00701moles of water vapor.

mass of water vapor = 0.00701 moles × 18g/mol = 0.126g

Therefore, 0.126 grams of water vapor will be produced from 0.500 grams of iron hydroxide.

If the structure of the crystal contains an identical component at the center of the cube then it is said to be BCC whereas if there are parts in the center of each face along with those at the corners of the cube, then it is FCC.

How do you identify the structure of a crystal?

Crystal structures may be narrated in several ways. The most usual manner is to refer to the size and shape of the cube and the locations of the atoms (or ions) within the cell. The crystal structure is set on by X-ray diffraction. A beam of X-rays strikes the crystal and the diffraction design is then used to study the structure, Matter can broadly be restricted into two categories based on its internal structure i.e. amorphous and crystalline. The morphology of crystals can be studied with the unaided eye in large well-evolve crystals and has been historically examined.

So we can conclude that the size of the unit cell and the positioning of atoms in a crystal may be set on from measurements of the diffraction of X-rays by the crystal, termed X-ray crystallography.

The pH of a buffer that is 0.086 M HF and 0.386 M LiF when the K₂ for HF is 3.5x 10-4 is 2.802

The pH of a buffer solution is given by Henderson Hasselback equation.

pH=pKa+log[A-]/[HA]

Substituting the values, we get

pH=-log(3.5x10^-4)+log(0.086/0.386)

pH=-log(3.5x10^-4)-0.653

pH=3.455-0.653

Which observation is clear evidence that matter is conserved in the chemical
reaction?

Answers

Law of conservation of mass gives clear evidence that matter is conserved in the chemical reaction

Experiments in the 1700s by a French chemist named Antoine Lavoisier led to the conclusion of conservation of mass. Lavoisier carefully measured the mass of reactants and products in multiple chemical reactions.

He carried out all the reactions inside a sealed jar. In each and every case, the total mass of the jar and its contents remained the same after the reaction as it was before the reaction took place.

This showed proof that matter was neither created nor destroyed in the reactions. Another outcome of Lavoisier’s research was the discovery of oxygen which was also a remarkable discovery as we all know.

The law of conservation of mass states that mass is neither created nor destroyed in a chemical reaction. For example, the carbon atom in coal becomes carbon dioxide when it is burned into ashes. The carbon atom changes from a solid structure to a gas but its mass remains the same. It does not change at all.

All these observations led to the theory that mass/ matter is conserved in a chemical reaction
