The moles of HNO₃ produced from the reaction of 81.0 g of NO₂ with excess water in the chemical reaction is 1.17 moles.

The balanced chemical reaction is -

3 NO₂(g) + H₂O(l) → 2 HNO₃(g) + NO(g)

First step is to calculate moles of NO₂ -

Number of moles = Given mass

                                 Molar mass

Moles of NO₂ = 81.0 g = 1.76 moles of NO₂

                          46.0 g

We have,

mass of NO₂ = 81.0 g

moles of NO₂ = 1.76 mol

So,

3 moles of NO₂ is required to make 2 moles of HNO₃

1.76 moles of NO₂ is required to make 2 x 1.76 moles of HNO₃

                                                                3

Moles of HNO₃ = 2 x 1.76 = 1.17 mol

                             3

Therefore,

moles of HNO₃ produced by the reaction of NO₂ with excess water is 1.17 moles.

The equilibrium quotient based on the following initial concentrations and predict whether the system with shift left or shift right is 3.10 x 10⁻⁴ right  

There are two types of gas-phase reactions: intramolecular and intermolecular. Precursor molecules are broken down into activated species in intramolecular reactions, which are then used in the CVD process.

Qc = [C] = equilibrium quotient ² / [A]² [B]³

Qc = (0.0383)² / (0.219)² (4.62) (4.62)³

Qc = 3.10 x 10⁻⁴

Kc = 5.00

Kc > Qc . so shifts to right

We use the ideal gas equation PV=nRT to account for these conditions, where P is the pressure in atmosphere (atm), V is the volume in liters (L), n is the number of moles, and R is the gas constant with a value of 08206 L atm mol-1 K-1, where T is the temperature in kelvin (K) and L is the atm.

The percent yield of CO₂ In the reaction CH₄ + 2O₂ → 2H₂O + CO₂ if 1600g of methane reacts with excess oxygen to produce 2200 is 67.5%.

To calculate the percent yield of CO₂ in the given reaction, we need to first calculate the theoretical yield of CO₂. This can be done by stoichiometric calculations using the balanced chemical equation:

CH₄ + 2O₂ → 2H₂O + CO₂

The molar mass of CH₄ is 16.04 g/mol. Therefore, 1600 g of CH₄ is equivalent to 100 moles of CH₄. According to the stoichiometry of the reaction, 1 mole of CH₄ produces 1 mole of CO₂. Therefore, the theoretical yield of CO₂ is also 100 moles.

The molar mass of CO₂ is 44.01 g/mol. Therefore, the theoretical yield of CO₂ in grams is 4401 g.

The actual yield of CO₂ given in the problem is 2200 g.

Therefore, the percent yield of CO₂ is:

Percent yield = (actual yield / theoretical yield) x 100%

Percent yield = (2200 g / 4401 g) x 100%

Percent yield = 0.499 x 100%

Percent yield = 49.9%.

Answer:

0.189 g

Explanation:

Step 1: Write the balanced equation

NCl₃ + 3 H₂O ⇒ NH₃ + 3 HCIO

Step 2: Calculate the moles corresponding to 1.33 g of NCl₃

The molar mass of NCl₃ is 120.36 g/mol.

1.33 g × 1 mol/120.36 g = 0.0111 mol

Step 3: Calculate the moles of NH₃ produced from 0.0111 moles of NCl₃

The molar ratio of NCl₃ to NH₃ is 1:1. The moles of NH₃ produced are 1/1 × 0.0111 mol = 0.0111 mol.

Step 4: Calculate the mass corresponding to 0.0111 moles of NH₃

The molar mass of NH₃ is 17.03 g/mol.

0.0111 mol × 17.03 g/mol = 0.189 g

To balance the equation and identify the type of reaction, let's start by assigning coefficients to each compound: 2H2O + 1SO3 -> 1H2SO4

To balance the equation, we need to ensure that the number of atoms on both sides is the same. Here, we have two hydrogen (H) atoms on the left side and two on the right side, so hydrogen is already balanced.

We have two oxygen (O) atoms on the left side and four on the right side, so we need to balance oxygen by adding a coefficient of 2 in front of the water molecule:

2H2O + 1SO3 -> 1H2SO4

Now the equation is balanced with two hydrogen, four oxygen, and one sulfur (S) atom on both sides.

The type of reaction represented by this equation is a combination or synthesis reaction. In a combination reaction, two or more substances combine to form a new compound. In this case, water (H2O) and sulfur trioxide (SO3) combine to form sulfuric acid (H2SO4).

Rate =\(k[A]^2[B]^2[C]^2\) with an overall reaction order of 6.

The rate law for a chemical reaction expresses the relationship between the rate of the reaction and the concentrations of the reactants. In the given reaction, 2A + 2B + 2C, the general rate law expression can be written as:

Rate =\(k[A]^a[B]^b[C]^c\)

However, since the coefficients in the balanced chemical equation represent the stoichiometric coefficients, they can also be used as the exponents in the rate law expression. Therefore, the rate law for the given reaction would be:

Rate =\(k[A]^2[B]^2[C]^2\)

Here, a = 2, b = 2, and c = 2 represent the exponents corresponding to the reactants A, B, and C, respectively. The overall order of the reaction is determined by adding the exponents:

Overall reaction order = a + b + c = 2 + 2 + 2 = 6

Hence, the rate law for the reaction 2A + 2B + 2C would be:

From the stoichiometry of the reaction, 0.094 g  of \(Cu^{2+}\) is contained in the reaction.

The reaction equation is given by; \(2Na_{3}PO_{4} (aq) + 3CuCl_{2} (aq) ----- > 6NaCl (aq) + Cu_{3}(PO_{4}) _{2} (s)\). We must note that the balanced reaction equation is the entry way into obtaining the correct stoichiometry of the reaction in order to solve the problem.

Number of moles of \(Na_{3}PO_{4}\) =  5.00 × 10−2 L *  0.173 mol L−1 = 0.00865 moles

If 2 moles of \(Na_{3}PO_{4}\) produces 1 mole of\(Cu_{3}(PO_{4}) _{2}\)

0.00865 moles of \(Na_{3}PO_{4}\) produces  0.00865 moles * 1 mole/2 moles

= 0.0043 moles of \(Cu3(PO4)2\)

Number of moles of \(Cu^{2+}\) = 0.0043 moles/3 = 0.00144 moles

2) Petrol is more flammable than diesel.

3) The formula will be C₁₀H₂₂.

4) The equation is; 2C8H18+25O2→16CO2+18H2O.

Depending on the precise composition and temperature, the viscosity of gasoline and diesel can change. In general, diesel is more viscous than gasoline. Higher viscosity fluids are thicker and flow more slowly than lower viscosity fluids because viscosity relates to the resistance of a fluid to flow.

Diesel is less flammable than gasoline. The lowest temperature at which gasoline can evaporate and turn into an ignitable combination in air is known as its flash point, and it is lower for gasoline. Compared to diesel fuel, petrol vapors are much more flammable and can ignite at lower temperatures.

The value of Kc for the given reaction is 0.0579 (rounded to four decimal places).

The formula for the equilibrium constant, Kc, of a reaction is given by the ratio of the product of the concentrations of the products raised to their respective stoichiometric coefficients to the product of the concentrations of the reactants raised to their respective stoichiometric coefficients.

The stoichiometric coefficients are the coefficients in the balanced chemical equation.

To determine the value of Kc for the reaction given by the following chemical equation:N2(g) + 3 H2(g) ⇌ 2 NH3(g)

we first need to write the expression for Kc.

The expression for Kc is given by the following formula:Kc = [NH3]² / [N2][H2]³.

We are given the equilibrium concentrations as follows:[N2]eq = 2.66 M[H2]eq = 0.64 M[NH3]eq = 3.34 M

We can substitute these values into the expression for Kc and obtain the following:Kc = (3.34)² / (2.66)(0.64)³ = 0.0579 (rounded to four decimal places).

The Lewis structure for ozone contains a central oxygen atom that has a double bond to one oxygen atom and a single bond with the other oxygen atom. The resonance structure of the ozone is shown in the attached figure below.

The oxygen molecule has a valency of -2. It can form two-sigma bonds or covalent bonds with the other atoms. Oxygen contains three lone pairs to form π bonds with other atoms. Ozone contains all three oxygen atoms and is a dihedral molecule with sp² hybridization.

Lewis structure is generally based on the octet rule which states that there should be eight electrons in the valence shell or orbit of an atom for a stable molecule.

The lone pair on the central oxygen atom repels the electrons in the two side bonds and adopt a bent molecular geometry. The expected geometry is the trigonal planar with a bond angle is 120°.

In an ozone molecule, six valence electrons for each molecule of Oxygen so the total number of valence electrons is 6 × 3 = 18. As both Oxygen atoms on the sides have the same electronegativity, therefore, the double bond keeps on shifting from both causing resonances.

Average atomic mass = (54Fe * 0.058 + 56Fe * 0.917 + 57Fe * 0.022 + 58Fe * 0.003) / (0.058 + 0.917 + 0.022 + 0.003)

Plugging in the numbers, we get:Average atomic mass = (54 * 0.058 + 56 * 0.917 + 57 * 0.022 + 58 * 0.003) / (0.058 + 0.917 + 0.022 + 0.003)

Average atomic mass = (31.12 + 51.592 + 1.254 + 0.174) / (0.058 + 0.917 + 0.022 + 0.003)

Average atomic mass = 84.066 / (0.058 + 0.917 + 0.022 + 0.003)Average atomic mass = 84.066 / 1

Average atomic mass = 84.066So, the average atomic mass of Iron is 84.066 atomic mass units (amu).
