The new volume [tex]V_{2}[/tex]) of the gas is approximately 1710 L when the temperature changes from 42 ∘C to 94 ∘C, assuming no change in pressure or amount of gas.

What is Temperature?

Temperature is a measure of the average kinetic energy of the particles in a substance, such as a gas, liquid, or solid. It is commonly measured in Celsius (°C), Fahrenheit (°F), or Kelvin (K) scales. Temperature determines the direction of heat transfer, which is the movement of energy between substances due to a temperature difference.

To use the ideal gas law, we need to convert the temperatures to Kelvin by adding 273.15 to each:

[tex]T_{1}[/tex] = 42 + 273.15 = 315.15 K

[tex]T_{2}[/tex]= 94 + 273.15 = 367.15 K

Since the pressure, amount of gas, and ideal gas constant remain constant in this problem, we can set up the following ratio:

([tex]V_{1}[/tex] / [tex]T_{1}[/tex]) = ([tex]V_{2}[/tex]/ [tex]T_{2}[/tex])

Plugging in the values:

(1.47 ×[tex]10^{3}[/tex]L / 315.15 K) = ([tex]V_{2}[/tex] / 367.15 K)

Now we can solve for [tex]V_{2}[/tex]:

[tex]V_{2}[/tex] = 1.47×[tex]10^{3}[/tex] L * 367.15 K / 315.15 K

[tex]V_{2}[/tex]≈ 1710 L (rounded to three significant figures)

Therefore, the new volume (V2) of the gas is approximately 1710 L when the temperature changes from 42 ∘C to 94 ∘C, assuming no change in pressure or amount of gas.

Answer: The units for molarity are moles/liter.

Similarly, the equation to find molarity is moles divided by liters.

Explanation:  

mol / L is a unit of molar concentration. These are the number of moles of dissolved material per liter of solution. 1 mol / L is also called 1M or 1molar. Mol / m3 is also a unit of molar concentration.

Molarity is expressed in units of moles per liter (mol / L). This is a very common unit, so it has its own symbol, which is the uppercase M. A solution with a concentration of 5 mmol / l is called a 5 M solution or has a concentration value of 5 mol.

The molar concentration of the solution is equal to the number of moles of the solute divided by the mass of the solvent (kilogram), and the molar concentration of the solution is equal to the number of moles of the solute divided by the volume of the solution (liter). increase.

a) The balanced equation is NaOH + HCl → NaCl + H2O

b)  The concentration of the hydrochloric acid is 0.655 mol L-1.

c)  The amount of hydroxide ions used is 0.010 mol.

d)  The concentration of the hydrochloric acid is 0.655 mol L-1.

(a) The balanced chemical equation for the reaction between sodium hydroxide and hydrochloric acid is:

NaOH + HCl → NaCl + H2O

(b) To find the average titre volume, we need to add up the four readings and divide by the number of readings:

Average titre volume = (17.00 mL + 14.96 mL + 15.02 mL + 15.00 mL) / 4 = 15.25 mL

However, it is important to convert this volume to liters (L) before using it in any calculations:

Average titre volume = 15.25 mL = 0.01525 L

(c) The amount of hydroxide ions used in the titration can be calculated using the balanced chemical equation and the volume and concentration of the sodium hydroxide solution:

Amount of NaOH used = concentration × volume

= 0.40 mol L-1 × 0.0250 L

= 0.010 mol

Since the balanced chemical equation shows that one mole of NaOH reacts with one mole of HCl, the amount of hydroxide ions used is also 0.010 mol.

(d) To calculate the concentration of the hydrochloric acid, we need to use the amount of hydrochloric acid used and the volume of the average titre reading:

Amount of HCl used = concentration × volume

= concentration × 0.01525 L

Since one mole of HCl reacts with one mole of NaOH, the amount of HCl used is equal to the amount of NaOH used, which we calculated in part (c):

Amount of HCl used = 0.010 mol

Substituting this value into the above equation gives:

0.010 mol = concentration × 0.01525 L

Solving for concentration gives:

concentration = 0.010 mol / 0.01525 L = 0.655 mol L-1

Therefore, the concentration of the hydrochloric acid is 0.655 mol L-1.

The balanced equation for the given chemical reaction is:2 NH3(g) + 5 F2(g) → N2F4(g) + 6 HF(g)

a. To produce 4.00 moles of HF, we can use the stoichiometry of the balanced equation.

From the balanced equation, we can see that the mole ratio of NH3 to HF is 2:6 or 1:3.

This means that for every 1 mole of NH3, we will get 3 moles of HF.

So, to produce 4.00 moles of HF, we will need 4.00 moles / 3 moles per mole of NH3 = 1.33 moles of NH3.

b. To calculate the grams of F2 required to react with 1.50 moles of NH3, we can use the stoichiometry of the balanced equation.

From the balanced equation, we can see that the mole ratio of NH3 to F2 is 2:5.

This means that for every 2 moles of NH3, we will need 5 moles of F2.

So, for 1.50 moles of NH3, we will need 5 moles F2 / 2 moles NH3 * 1.50 moles NH3 = 3.75 moles of F2.

To convert moles of F2 to grams, we need to know the molar mass of F2, which is 2 x 19.00 g/mol = 38.00 g/mol.

So, the grams of F2 required to react with 1.50 moles of NH3 is 3.75 moles of F2 * 38.00 g/mol = 142.50 g of F2.

c. To calculate the grams of N2F4 that can be produced from 3.40 grams of NH3, we can use the stoichiometry of the balanced equation.

From the balanced equation, we can see that the mole ratio of NH3 to N2F4 is 2:1.

This means that for every 2 moles of NH3, we will produce 1 mole of N2F4.

First, let's convert 3.40 grams of NH3 to moles. The molar mass of NH3 is 1 x 14.01 g/mol + 3 x 1.01 g/mol = 17.03 g/mol.

So, 3.40 g of NH3 / 17.03 g/mol = 0.20 moles of NH3.

Now, using the mole ratio of NH3 to N2F4, we have 0.20 moles of NH3 * 1 mole of N2F4 / 2 moles of NH3 = 0.10 moles of N2F4.

To convert moles of N2F4 to grams, we need to know the molar mass of N2F4, which is 2 x 14.01 g/mol + 4 x 19.00 g/mol = 104.00 g/mol.

So, the grams of N2F4 that can be produced from 3.40 grams of NH3 is 0.10 moles of N2F4 * 104.00 g/mol = 10.40 g of N2F4.

The equation given is not balanced. Thus,  when balanced the equation becomes:

2 Al(NO₃)₃ + 3 Na₂SO₄ → Al₂(SO₄)₃ + 6 NaNO₃

The molar mass of Al(NO₃)₃ is:

Al(NO₃)₃ = 1(Al) + 3(N) + 9(O) = 213 g/mol

The molar mass of Na₂SO₄ is:

Na₂SO₄ = 2(Na) + 1(S) + 4(O) = 142 g/mol

From the balanced equation, we can see that 2 moles of Al(NO₃)₃ react with 3 moles of Na2SO4 to produce 1 mole of Al₂(SO₄)₃. Therefore, we can calculate the number of moles of Al(NO₃)₃ and Na₂SO₄ that react:

Number of moles of Al(NO₃)₃ = 4 g / 213 g/mol = 0.0188 mol

Number of moles of Na₂SO₄ = 3 g / 142 g/mol = 0.0211 mol

From the balanced equation, we can see that 2 moles of Al(NO₃)₃ produce 1 mole of Al₂(SO₄)₃. Therefore, the number of moles of Al₂(SO₄)₃ produced is:

Number of moles of Al₂(SO₄)₃ = 0.0188 mol / 2 * 1 = 0.0094 mol

The molar mass of Aluminum Sulfate (Al₂(SO₄)₃) is:

Al₂(SO₄)₃ = 2(Al) + 3(S) + 12(O) = 342 g/mol

Therefore, the mass of Aluminum Sulfate produced is:

Mass of Al₂(SO₄)₃ = Number of moles of Al₂(SO₄)₃ * Molar mass of Al₂(SO₄)₃

= 0.0094 mol * 342 g/mol

= 3.21 g

Hence, 3.21 grams of Aluminum Sulfate are liberated when 4 g of Aluminum Nitrate change state with 3 g of Sodium Sulfate.

The molar mass of the unknown gas is 28 g/mol.

Graham's law of effusion states that the rate of effusion (the escape of gas molecules through a tiny hole) of a gas is inversely proportional to the square root of its molar mass, at constant temperature and pressure. This means that lighter gases effuse (escape through a hole) faster than heavier gases, all other factors being equal.

We can use Graham's law of effusion to solve this problem:

Rate of effusion is inversely proportional to the square root of molar mass.

Thus, we can write:

(rate of effusion of O₂) / (rate of effusion of the unknown gas) =

sqrt(molar mass of the unknown gas) / sqrt(molar mass of O₂)

Let's call the molar mass of the unknown gas "M". We can set up the following system of equations using the information given in the problem:

4/1 = (rate of effusion of O₂) / (rate of effusion of the unknown gas)

(rate of effusion of O₂) = 1/220

(rate of effusion of the unknown gas) = 1/245

Plugging in these values, we get:

4/1 = (1/220) / (1/245)

4/1 = 49/44

Solving for the rate of effusion of the unknown gas, we get:

(rate of effusion of the unknown gas) = (1/245) / (49/44) = 4/539

Now we can use Graham's law of effusion to find the molar mass of the unknown gas:

(rate of effusion of O₂) / (rate of effusion of the unknown gas) =

sqrt(molar mass of the unknown gas) / sqrt(molar mass of O₂)

(1/220) / (4/539) = sqrt(M) / sqrt(32)

Solving for M, we get:

M = 28 g/mol

The percent yield of copper(I) sulfide in this experiment is 31.83%.

What is percent yield?

To calculate the percent yield, we need to compare the actual yield (the amount of product that was obtained in the experiment) with the theoretical yield (the amount of product that should have been obtained if the reaction had gone to completion).

The balanced chemical equation for the reaction between copper and sulfur to form copper(I) sulfide is:

Cu + S →  [tex]Cu_{2}S[/tex]

The molar mass of Cu is 63.55 g/mol, and the molar mass of S is 32.06 g/mol. The molar mass of  [tex]Cu_{2}S[/tex]  is 159.17 g/mol.

First, we need to calculate the theoretical yield of copper(I) sulfide using the amount of copper used in the experiment:

5 g Cu × (1 mol Cu / 63.55 g Cu) × (1 mol [tex]Cu_{2}S[/tex] / 1 mol Cu) × (159.17 g  [tex]Cu_{2}S[/tex] / 1 mol [tex]Cu_{2}S[/tex] ) = 12.57 g  [tex]Cu_{2}S[/tex]

So the theoretical yield of copper(I) sulfide is 12.57 g.

The actual yield obtained in the experiment is 4 g.

The percent yield is then:

percent yield = (actual yield / theoretical yield) × 100%

percent yield = (4 g / 12.57 g) × 100%

percent yield = 31.83%

Therefore, the percent yield of copper(I) sulfide in this experiment is 31.83%.

What is theoretical yield ?

The theoretical yield is the amount of product that would be obtained in a chemical reaction if it went to completion, meaning that all the limiting reactant was used up and no product was lost. It is calculated using stoichiometry, which involves balancing the chemical equation for the reaction and using the coefficients to determine the mole ratio between the reactants and products.

Theoretical yield is often used as a reference value to compare with the actual yield obtained in an experiment, which is the amount of product actually obtained from the reaction. The percent yield can then be calculated by dividing the actual yield by the theoretical yield and multiplying by 100%.

The pH after 15.0 mL of 0.210 KOH is added in the titration of 55.0 mL of 0.210 M HClO is 4.56.

To solve this problem, we need to use the balanced chemical equation for the reaction between KOH and HClO:

HClO + KOH → KClO + H2O

We can see that for every mole of KOH added, one mole of HClO will react. Therefore, the number of moles of HClO in 55.0 mL of 0.210 M HClO is:

n(HClO) = M(HClO) x V(HClO) = 0.210 mol/L x 0.0550 L = 0.0116 mol

When 15.0 mL of 0.210 M KOH is added, the number of moles of KOH added is:

n(KOH) = M(KOH) x V(KOH) = 0.210 mol/L x 0.0150 L = 0.00315 mol

Since the reaction is a neutralization reaction, the moles of HClO left after the reaction will be:

n(HClO) = n(HClO)initial - n(KOH) = 0.0116 mol - 0.00315 mol = 0.00845 mol

We can now use the equilibrium expression for the ionization of HClO in water to calculate the pH of the solution:

HClO + H2O ⇌ H3O+ + ClO-

Ka = [H3O+][ClO-]/[HClO]

At equilibrium, the concentrations of H3O+ and ClO- can be assumed to be equal to the concentration of HClO that remains unreacted, since HClO is a weak acid and does not dissociate completely in water. Therefore:

[H3O+] = [ClO-] = [HClO] = 0.00845 mol / (0.0550 L + 0.0150 L) = 0.105 M

Substituting these values into the equilibrium expression for Ka:

Ka = [H3O+][ClO-]/[HClO] = (0.105 M)² / 0.00845 M = 1.31 x 10⁻⁶

pKa = -log(Ka) = -log(1.31 x 10⁻⁶) = 5.88

pH = 1/2(pKw - pKa) = 1/2(14.00 - 5.88) = 4.56

(a). The rate of change in the concentration of [tex]H_{2}O[/tex] and the rate of change in the concentration of [tex]CO_{2}[/tex] is: 0.072 M/s.

(b). The rate of consumption of [tex]O_{2}[/tex] is: 0.10 mol  [tex]O_{2}[/tex] per second.

What is concentration?

a) To determine the rates of change in the concentrations of  [tex]CO_{2}[/tex]  and [tex]H_{2}O[/tex] , we first need to determine the stoichiometric coefficients of each reactant and product in the balanced chemical equation.

From the balanced chemical equation:

1 mol  [tex]C_{2}H_{4}[/tex] reacts to form 2 mol  [tex]CO_{2}[/tex] and 2 mol [tex]H_{2}O[/tex].

Therefore, the rate of change in the concentration of [tex]CO_{2}[/tex]  is:

(0.036 M/s) x (2 mol [tex]CO_{2}[/tex] /1 mol  [tex]C_{2}H_{4}[/tex]) = 0.072 M/s

The rate of change in the concentration of [tex]H_{2}O[/tex]  is also:

(0.036 M/s) x (2 mol [tex]H_{2}O[/tex] /1 mol [tex]C_{2}H_{4}[/tex]) = 0.072 M/s

What is consumption?

b) To find the rate of consumption of  [tex]C_{2}H_{4}[/tex], we can use the formula:

rate = Δ[ [tex]C_{2}H_{4}[/tex]]/Δt

Initially, the concentration of  [tex]C_{2}H_{4}[/tex] is:

n/V = 2 mol / 2.0 L = 1.0 M

After 1 minute, the concentration of  [tex]C_{2}H_{4}[/tex] is:

n/V = 2 mol / 2.0 L = 1.0 M

(change in concentration is 0)

Therefore, the rate of consumption of  [tex]C_{2}H_{4}[/tex] is:

rate = Δ[ [tex]C_{2}H_{4}[/tex]]/Δt = (1.0 M - 1.0 M) / 60 s = 0 M/s

The rate of [tex]O_{2}[/tex] consumption can be found by using the stoichiometric ratio between  [tex]C_{2}H_{4}[/tex] and [tex]O_{2}[/tex] in the balanced chemical equation:

1 mol  [tex]C_{2}H_{4}[/tex] reacts with 3 mol  [tex]O_{2}[/tex] .

Initially, we have 6 mol [tex]O_{2}[/tex] in the container.

After 1 minute, 2 mol  [tex]C_{2}H_{4}[/tex] are consumed, which corresponds to the consumption of 6 mol  [tex]O_{2}[/tex] :

6 mol  [tex]O_{2}[/tex] / 2 mol  [tex]C_{2}H_{4}[/tex] = 3 mol  [tex]O_{2}[/tex] / 1 mol  [tex]C_{2}H_{4}[/tex]

Therefore, the rate of consumption of [tex]O_{2}[/tex] is:

rate = (3 mol  [tex]O_{2}[/tex]  / 1 mol  [tex]C_{2}H_{4}[/tex]) x (0.0333 mol  [tex]C_{2}H_{4}[/tex]/s) = 0.10 mol  [tex]O_{2}[/tex]  per second.

B, Electrons flow from the anode to the cathode is true for a voltaic cell constructed in the first part of the experiment.

A voltaic cell, also known as a galvanic cell, is an electrochemical cell that converts chemical energy into electrical energy. It consists of two half-cells, each with an electrode and an electrolyte solution. The two half-cells are connected by a wire and a salt bridge.

During operation, the electrons flow from the anode (the electrode where oxidation occurs) to the cathode (the electrode where reduction occurs) through the wire, while ions flow through the salt bridge to balance the charges in the two half-cells. This generates an electric current that can be used to power electrical devices.

The reactions with a positive Δrxn are:

A(g) + B(g) ⟶ 3C(g)

A(s) + B(s) ⟶ C(g)

The entropy change (Δrxn) of a reaction indicates the change in the degree of randomness or disorder of the system during the reaction. If the number of product molecules is greater than the number of reactant molecules, the disorder of the system usually increases, resulting in a positive Δrxn. Therefore, we can determine the answer by analyzing the stoichiometry of each reaction:

A(g) + B(g) ⟶ C(g)

In this reaction, the number of product molecules is less than the number of reactant molecules, so the disorder of the system decreases. Therefore, this reaction has a negative Δrxn.

A(g) + B(g) ⟶ 3C(g)

In this reaction, the number of product molecules is greater than the number of reactant molecules, so the disorder of the system increases. Therefore, this reaction has a positive Δrxn.

A(s) + B(s) ⟶ C(g)

In this reaction, the solid reactants are combining to form a gaseous product. The disorder of the system is expected to increase, resulting in a positive Δrxn.

2A(g) + B(g) ⟶ C(g)

In this reaction, the number of product molecules is less than the number of reactant molecules, so the disorder of the system decreases. Therefore, this reaction has a negative Δ rxn.
