Engineers Julie and Walter operate a reactor where two unbalanced, gas phase reactions occur: CH3COOH+H2→C2H5OH+H2O and C2H5OH→(C2H5)2O+H2O. In the first reaction, acetic acid (CH3COOH) and hydrogen (H2) react to produce ethanol (C2H5OH) and water (H2O); and ethanol decomposes to diethyl ether ((C2H5)2O) and water in the second reaction. A stream of 67.8 mol/s hydrogen and the balance acetic acid at 147°C is fed to the reactor, which operates at steady state. The stream exiting the reactor contains acetic acid, hydrogen, ethanol, water, and diethyl ether at 417°C. The component flow rate of acetic acid exiting the reactor is 3.81 mol/s. The fraction conversion of acetic acid is 71.6%, and the selectivity, which is the ratio of the amount of ethanol to diethyl ether in the exiting stream, is 3.14. Assume all components are in the gas phase and no phase changes occur in the reactor.

Find the component molar flow rate of acetic acid(AA) entering the reactor.

When light travels from less dense air to denser glass or water, it slows down. Slowing down of a ray of light changes the direction of the ray of light.

Light that travels in a straight line in one direction is called a ray of light. When a group of light emanates from a source, it is called a beam of light. A beam of light is defined as the path of a photon or a group of photons traveling through a space appearing as a column of light.

There are three types of light rays. They are

Example of a beam is a beam of light with a pass from a laser or laser pointer. A beam of light is made up of particles called photons that carry specific amounts of energy. We cannot measure the length of a beam.

Thus, when light travels from less dense air to denser glass or water, it slows down. Slowing down of a ray of light changes the direction of the ray of light.

The above equation can be balance as follow:

Na₃PO₄ + HCl —> NaCl + H₃PO₄

There are 3 atoms of Na on the left side and 1 atom on the right side. It can be balance by writing 3 before NaCl as shown below:

Na₃PO₄ + HCl —> 3NaCl + H₃PO₄

There are 3 atoms of Cl on the right side and 1 atom on the left side. It can be balance by writing 3 before HCl as shown below:

Answer:

When the balloon is taken outside if the outside temperature is lower than the temperature inside the shed, the volume of the helium gas will decrease according to Charles' law. However, if the temperatureoutside is higher than inside the shed, the volume of the helium gas in the weather balloons will increase.

Note: The question is not complete. Assumptionshas been made about the temperature.

Explanation:

According to Charles' law of gases, the volume of a given mass of gas is directly proportional to its temperature in Kelvin provided its pressure remains constant.

Mathematically, V1T1 = V2T2

Given that the volume of the helium gas inside the weather balloon is 34.1 L at a temperature of 5 °C;

When the balloon is taken outside if the outside temperature is lower than the temperature inside the shed, the volume of the helium gas will decrease according to Charles' law. However, if the temperatureoutside is higher than inside the shed, the volume of the helium gas in the weather balloons will increase.

Assuming, the temperature outside the shed was 6.5 °C:

V1 = 34.1 L, T1 = 5.°C or 5.0 × 10^-10 °C = 273.1500000005

V2 = ?, T2 = 6.5 °C 6.5 × 10^-10 °C = 273.15000000065

V2 = V1T1/T2

V2 = (34.1 × 273.1500000005) / 273.15000000065

V2 = 34.1 L

Due the very small increase in temperature, the volume of the balloon increases only very slightly that is increase that it is negligible.

Answer:

10 L

Explanation:

We'll begin by calculating the number of mole in 9 g and 1 g of He. This can be obtained as follow:

Mass of He = 9 g

Molar mass of he= 4 g/mol

Mole of He =?

Mole = mass /Molar mass

Mole of He = 9/4

Mole of He = 2.25 moles

Mass of He = 1 g

Molar mass of he= 4 g/mol

Mole of He =?

Mole = mass /Molar mass

Mole of He = 1/4

Mole of He = 0.25 moles

Finally, we shall determine the new volume of the balloon as follow:

Initial mole (n₁) = 0.25 mole

Initial volume (V₁) = 1 L

Final mole (n₂) = 0.25 + 2.25 = 2.5 moles

Final volume (V₂) =?

V₁/n₁ = V₂/n₂

1 / 0.25 = V₂ / 2.5

4 = V₂ / 2.5

Cross multiply

V₂ = 4 × 2.5

V₂ = 10 L

Therefore, the new volume of the balloon is 10 L

So they react to produce carbonic acid and sulfate.

Answer:

0.1332 L

Explanation:

The balanced chemical equation is the following:

2 Na(s) + 2 H₂O(l) → 2 NaOH(aq) + H₂(g)

According to the equation, 2 moles of water (H₂O) produce 1 mol of hydrogen (H₂). So, the stoichiometric ratio is 1 mol H₂/2 mol H₂O. To calculate how many moles of H₂O we need to produce 3.7 moles of H₂, we multiply the moles by the stoichiometric ratio:

3.7 moles H₂ x 2 mol H₂O/1 mol H₂ = 7.4 moles H₂O

Now, we have to convert the moles of water to liters. For this, we have to consider the molecular weight (MW) of water and its density (let's consider 1.0 g/mL).

MW(H₂O) = (2 x 1 g/mol H) + 16 g/mol = 18 g/mol

7.4 moles H₂O x 18 g/mol = 133.2 g

133.2 g/(1.0 g/ml) = 133.2 mL

133.2 ml x 1 L/1000 ml = 0.1332 L

Therefore, approximately 0.13 liters of water are needed.

Answer:

a) 0.099 L

b) 9.9

Explanation:

Now, given the equation for the decomposition of H2O2;

2H2O2(l) ------> 2H2O(l) + O2(g)

Mass of H2O2;

percent w/v concentration = mass/volume * 100

volume = 10.0-mL

percent w/v concentration = 3.0 percent

mass of  H2O2 = x

3 = x/ 10 * 100

30 = 100x

x = 30/100

x = 0.3 g of H2O2

Number of moles in  0.3 g of H2O2 = mass/ molar mass

Molar mass of H2O2 = 34.0147 g/mol

Number of moles in  0.3 g of H2O2 = 0.3g/34.0147 g/mol

= 0.0088 moles

From the reaction equation;

2 moles of H2O2 yields 1 mole of oxygen

0.0088 moles of H2O2 = 0.0088 * 1/2  = 0.0044 moles of oxygen

If 1 mole of oxygen occupies 22.4 L

0.0044 moles of oxygen occupies 0.0044 *  22.4/1

= 0.099 L

b) initial volume of the H2O2 solution = 10 * 10-3 L

Hence, ratio of the volume of O2 collected to the initial volume of the H2O2 solution = 0.099 L/10 * 10-3 L = 9.9

Answer:

³₂He

Explanation:

From the question given above, the following equation was obtained

²₁H + ²₁H —> ¹₀n + __

Let ᵇₐX be the missing part of the equation. Thus, the equation becomes:

²₁H + ²₁H —> ¹₀n + ᵇₐX

Next, we shall determine b, a, and X. This can be obtained as follow:

2 + 2 = 1 + b

4 = 1 + b

Collect like terms

b = 4 – 1

b = 3

1 + 1 = 0 + a

2 = 0 + a

a = 2

ᵇₐX => ³₂X => ³₂He

Thus the equation is:

²₁H + ²₁H —> ¹₀n + ᵇₐX

²₁H + ²₁H —> ¹₀n + ³₂He

The missing part is ³₂He

Answer:

552 g of LiNO₃

Explanation:

From the question given above, the following data were obtained:

Volume of solution = 2 L

Molarity of LiNO₃ = 4 M

Mass of LiNO₃ =?

Next, we shall determine the number of mole of LiNO₃ in the solution. This can be obtained as follow:

Volume of solution = 2 L

Molarity of LiNO₃ = 4 M

Mole of LiNO₃ =?

Molarity = mole /Volume

4 = mole of LiNO₃ / 2

Cross multiply

Mole of LiNO₃ = 4 × 2

Mole of LiNO₃ = 8 moles

Finally, we shall determine the mass of of LiNO₃ needed to prepare the solution. This is can be obtained as follow:

Mole of LiNO₃ = 8 moles

Molar mass of LiNO₃ = 7 + 14 + (16×3)

= 7 + 14 + 48

= 69 g/mol

Mass of LiNO₃ =?

Mole = mass /Molar mass

8 = Molar mass of LiNO₃ /69

Cross multiply

Molar mass of LiNO₃ = 8 × 69

Molar mass of LiNO₃ = 552 g

Thus, 552 g of LiNO₃ is needed to prepare the solution.

Answer:

boron compound - known as Borax

Explanation:

Answer:

10.57

Explanation:

Step 1: Given and required data

Step 2: Write the basic dissociation reaction for NH₃

NH₃(aq) + H₂O(aq) ⇄ NH₄⁺(aq) + OH⁻(aq)

Step 3: Calculate the concentration of OH⁻

We will use the following expression.

[OH⁻] = √(Kb × Cb)

[OH⁻] = √(1.8 × 10⁻⁵ × 0.0075 M) = 3.7 × 10⁻⁴ M

Step 4: Calculate the concentration of H⁺

We will use the water ion product.

Kw = 1.0 × 10⁻¹⁴ = [H⁺] × [OH⁻]

[H⁺] = 1.0 × 10⁻¹⁴/3.7 × 10⁻⁴ = 2.7 × 10⁻¹¹ M

Step 5: Calculate the pH of the solution

We will use the definition of pH.

pH = -log [H⁺] = -log 2.7 × 10⁻¹¹ = 10.57
