the products formed from the reaction of halogenoalkane + ethanolic aqueous silver nitrate​

As per the given data, 1.6 grams of oxygen reacted in this experiment.

To calculate the amount of oxygen that reacted in the experiment, we need to determine the difference in the mass of X oxide (X,O) formed and the mass of X initially used.

Given:

Mass of X = 4.6 g

Mass of X oxide (X,O) = 6.2 g

To find the amount of oxygen that reacted:

Mass of oxygen = Mass of X oxide - Mass of X

= 6.2 g - 4.6 g

= 1.6 g

Therefore, 1.6 grams of oxygen reacted in this experiment.

Calculate the mass of 1 mole of X:

Given that the mass of X is 4.6 g, we can calculate the molar mass of X by dividing the mass by the number of moles:

Molar mass of X = Mass of X / Number of moles of X

Molar mass of X = 4.6 g / 0.1 mol

Molar mass of X = 46 g/mol

Therefore, the mass of 1 mole of X is 46 grams.

Thus, the answer is 46 grams.

The reaction of CuCl2, HNO3, and AgNO3 is a redox reaction. In a redox reaction, one substance loses electrons and is oxidized, while another substance gains electrons and is reduced. In this reaction, CuCl2 is oxidized to Cu2+, HNO3 is reduced to NO, and AgNO3 is reduced to Ag.

The balanced equation for the reaction is:

CuCl2 + 2HNO3 + 2AgNO3 → Cu2+ + 2NO + 2AgCl

The products of the reaction are copper(II) ions, nitrogen monoxide gas, and silver chloride precipitate.

Here are some of the properties of phenol:

Phenol is a white crystalline solid that is soluble in water.

Phenol has a strong, characteristic odor.

Phenol is a mild acid.

Phenol is toxic and can cause burns to the skin and eyes.

Phenol is used in a variety of products, including disinfectants, antiseptics, and plastics.

The resulting pH of the solution is 1.74(approx).

To solve this problem, we need to use the concept of acid-base equilibrium and the pH scale. The addition of sulfuric acid will increase the concentration of H+ ions in the solution, which will shift the equilibrium of the \(H_2S\)/HS- system. We can use the following equation to calculate the pH of the resulting solution:

Ka = [H+][HS-]/\(H_2S\)]

where Ka is the acid dissociation constant for \(H_2S\), [\(H_2S\)], [HS-], and [H+] are the concentrations of the \(H_2S\), HS-, and H+ ions, respectively.

First, we need to calculate the initial concentrations of\(H_2S\) and HS- in the solution:

[\(H_2S\)] = 0.505 M

[HS-] = 0.505 M

Next, we need to calculate the amount of H+ ions added to the solution by 1 mL of concentrated sulfuric acid. To do this, we can use the following equation:

[H+] = (n/V) = (18.4 mol/L) x (1x\(10^{-3}\) L) = 1.84 x\(10^{-2}\)mol

where n is the amount of sulfuric acid added in moles, V is the volume of the solution in liters, and 18.4 mol/L is the concentration of the sulfuric acid.

Now, we can calculate the new concentrations of \(H_2S\), HS-, and H+ ions in the solution:

[\(H_2S\)] = [\(H_2S\)]0 - [H+] = 0.505 - 1.84x\(10^{-2}\)= 0.486 M

[HS-] = [HS-]0 + [H+] = 0.505 + 1.84x\(10^{-2}\) = 0.524 M

[H+] = 1.84 x \(10^{-2}\)M

Finally, we can use the equation for Ka to calculate the pH of the resulting solution:

Ka = 1.1 x \(10^{-7}\)

[H+] x [HS-]/[\(H_2S\)] = Ka

pH = -log[H+]

Substituting the values, we get:

(1.84 x \(10^{-2}\)) x (0.524)/(0.486) = 1.98 x \(10^{-2}\)

pH = -log(1.98 x \(10^{-2}\)) = 1.74(approx)

Therefore, the resulting pH of the solution is 1.74(approx)

A) The chemical equation for the reaction is \(Cl_2(aq) + 2KBr(aq)\) ⟶ \(2KCl(aq) + Br_2(aq)\)

B)No reaction occurs when elemental iodine is mixed with lithium chloride. \(I_2(aq) + 2LiCl(aq)\)⟶ No Reaction

A) To predict whether a reaction will occur when elemental chlorine (\(Cl_2\)) and potassium bromide (KBr) are mixed, we can refer to the activity series for the halogens. According to the activity series, chlorine is more reactive than bromine. Therefore, chlorine can displace bromine from its compounds.

The chemical equation for the reaction between chlorine and potassium bromide can be written as:

\(Cl_2(aq) + 2KBr(aq)\) ⟶ \(2KCl(aq) + Br_2(aq)\)

In this reaction, chlorine displaces bromine from potassium bromide, resulting in the formation of potassium chloride and elemental bromine.

B) Similarly, to predict whether a reaction will occur when elemental iodine (\(l_2\)) and lithium chloride (LiCl) are mixed, we can refer to the activity series. In the halogen activity series, iodine is less reactive than chlorine and bromine. Therefore, it is less likely for iodine to displace chlorine or bromine from their compounds.

The chemical equation for the reaction between iodine and lithium chloride can be written as:

\(I_2(aq) + 2LiCl(aq)\)⟶ No Reaction

No reaction occurs because iodine is less reactive than chlorine, and lithium chloride does not react with iodine under these conditions.

Therefore, when elemental chlorine is mixed with potassium bromide, a reaction occurs and chlorine displaces bromine. On the other hand, no reaction occurs when elemental iodine is mixed with lithium chloride.

Answer:

Option A) CO(g) + 1/2O2(g) <=> CO2(g).

Explanation:

A background knowledge of reaction rates shows that pressure will only affect gaseous reactant.

Further more, we understood that for pressure to effectively affect gaseous molecules, the total volume of the gaseous reactant must be different from the total volume of the gaseous products.

Now, let us consider the equation given in the question:

A) CO(g) + 1/2O2(g) <=> CO2(g).

B) CaCO3(s) <=> CaO(s) + CO2(g).

C) 2H2(g) + O2(g) <=> 2H2O(l).

D) 2Hg(l) + O2(g) <=> 2HgO(s).

E) CO2(g) + H2(g) <=> CO(g) + H2O(g).

From the above, only option A and E has gaseous reactant and product.

For option A:

CO(g) + 1/2O2(g) <=> CO2(g).

Total volume of reactant = 1 + 1/2 = 3/2 L

Total volume of product = 1 L

Since the volume of the reactant and that of the product are different, therefore, a change in pressure will affect the reaction.

For option E:

CO2(g) + H2(g) <=> CO(g) + H2O(g).

Total volume of reactant = 1 + 1 = 2 L

Total volume of product = 1 + 1 = 2 L

Since the volume of the reactant and that of the product are the same, therefore, a change in pressure will have no effect in the reaction.

The equilibrium equation, CO2(g) + H2(g) ⇄ CO(g) + H2O(g), is not affected by pressure changes at constant temperature because there are equal volumes of reactants and products on both sides of reaction equation.

For a gas phase reaction, changes in pressure would affect the direction in which the reaction moves. When the pressure is increased, the reaction moves in the direction of lesser volumes. When the pressure is decreased, the reaction moves in the direction of greater volumes.

For the reaction; CO2(g) + H2(g) ⇄ CO(g) + H2O(g), there are equal volumes of reactants and products on either side of the reaction equation. Therefore, the equilibria would not be affected by pressure changes at constant temperature.

Approximately 4.37 x 10^23 molecules of HCl would be required to form 34.52 g of MgCl₂.

To determine the number of molecules of HCl required to form 34.52 g of MgCl₂, we need to use the molar mass and stoichiometry of the balanced equation:

Mg(OH)₂(s) + 2 HCl(aq) → 2 H₂O(l) + MgCl₂(aq)

The molar mass of MgCl₂ is 95.21 g/mol.

First, we need to calculate the number of moles of MgCl₂ formed:

Moles of MgCl₂ = mass of MgCl₂ / molar mass of MgCl₂

Moles of MgCl₂ = 34.52 g / 95.21 g/mol

Moles of MgCl₂ = 0.363 mol

According to the balanced equation, the stoichiometric ratio between HCl and MgCl₂ is 2:1. Therefore, the moles of HCl required can be calculated as follows:

Moles of HCl = 2 * Moles of MgCl₂

Moles of HCl = 2 * 0.363 mol

Moles of HCl = 0.726 mol

To calculate the number of molecules, we need to use Avogadro's number, which is approximately 6.022 x 10^23 molecules/mol.

Number of molecules of HCl = Moles of HCl * Avogadro's number

Number of molecules of HCl = 0.726 mol * 6.022 x 10^23 molecules/mol

Number of molecules of HCl = 4.37 x 10^23 molecules

Answer:

Volume = 3.4 L

Explanation:

In order to calculate the volume of CO₂ produced when 15.2 g of CaCO₃ is heated, we need to first write out the balanced equation of the thermal decomposition of CaCO₃:

CaCO₃ (s) + [Heat] ⇒ CaO (s) + CO₂ (g)

Now, let's calculate the number of moles in 15.2 g CaCO₃:

mole no. = \(\mathrm{\frac{mass}{molar \ mass}}\)

                 = \(\frac{15.2}{40.1 + 12 + (16 \times 3)}\)

                 = 0.1518 moles

From the balanced equation above, we can see that the stoichiometric molar ratios of CaCO₃ and CO₂ are equal. Therefore, the number of moles of CO₂ produced is also 0.1518 moles.

Hence, from the formula for the number of moles of a gas, we can calculate the volume of  CO₂:

mole no. = \(\mathrm{\frac{Volume \ in \ L}{22.4}}\)

⇒ \(0.1518 = \mathrm{\frac{Volume}{22.4}}\)

⇒ Volume = 0.1518 × 22.4

                 = 3.4 L

Therefore, if 15.2 g of CaCO₃ is heated, 3.4 L of CO₂ is produced at STP.

PCl₃ + Cl₂ → PCl

From the equation, the stoichiometric ratio between PCl₃ and Cl₂ is 1:1. This means that for every 1 mole of PCl₃, 1 mole of Cl₂ is needed to completely react.

Given that we have 5.40 moles of PCl₃, we can conclude that we also need 5.40 moles of Cl₂ to completely react.

Therefore, 5.40 moles of chlorine gas are needed to completely react with 5.40 moles of PCl₃ in the reaction.

2. To calculate the number of grams of NO₂ produced, we need to determine the molar mass of N₂O and the stoichiometry of the reaction.

The molar mass of N₂O can be calculated as follows:

N₂O:

N = 2 atoms of nitrogen

O = 1 atom of oxygen

The molar mass of nitrogen (N) = 14.01 g/mol

The molar mass of oxygen (O) = 16.00 g/mol

Molar mass of N₂O = (2 * 14.01 g/mol) + (1 * 16.00 g/mol) = 44.02 g/mol

Now, we need to determine the stoichiometry of the reaction to find the mole ratio between N₂O and NO₂.

From the balanced equation:

N₂O(g) + O₂(g) → 2 NO₂(g)

According to the balanced equation, 1 mole of N₂O reacts to produce 2 moles of NO₂.

Now, let's calculate the number of moles of N₂O using its molar mass:

Moles of N₂O = mass of N₂O / molar mass of N₂O

Moles of N₂O = 315.0 g / 44.02 g/mol

Moles of N₂O ≈ 7.14 mol

Since the stoichiometric ratio between N₂O and NO₂ is 1:2, we can determine the number of moles of NO₂ produced:

Moles of NO₂ = 2 * moles of N₂O

Moles of NO₂ = 2 * 7.14 mol

Moles of NO₂ ≈ 14.28 mol

Finally, we can calculate the mass of NO₂ produced using its molar mass:

Mass of NO₂ = moles of NO₂ * molar mass of NO₂

Mass of NO₂ = 14.28 mol * (46.01 g/mol)  (molar mass of NO₂)

Mass of NO₂ ≈ 657.42 g

Therefore, approximately 657.42 grams of NO₂ are produced when 315.0 grams of N₂O reacts with excess oxygen gas.
