Hydrogen gas reacts with chlorine gas to form hydrogen chloride as shown in the following reaction: H2 (9) + Cl2 (g) + 2HCl (9) If a 454.4 g sample of chlorine gas (MM = 71.0 g/mol) was reacted with excess hydrogen at 565 K and 2.30 atm, how many grams of hydrogen chloride gas (MM = 36.5 g/mol) are produced? g Your answer should be rounded to three significant figures. Do not include units in your answer​

Answers

Answer 1

Answer:

467

Explanation:

ncl2 = 454.4x1/(71.0 g/mol) = 6.40 mols cl2

6.40 mols cl2 x 2molsHCL/1moleCL2 x 36.5g/1moleHCL = 467 g HCL

Answer 2

One mole of chlorine gas gives two moles of hydrogen chloride. Thus, 454.4 g of chlorine gas will give 467.2 g of hydrogen chloride.

What is hydrogen chloride?

Hydrogen chloride is a covalent compound formed by the electron sharing of chlorine and hydrogen. It normally exists in gaseous state and can be liquified to the acidic form.

As per the balanced reaction one mole of chlorine gas gives two moles of hydrogen chloride gas. The molecular mass of chlorine gas is 71 g/mol. The molar mass of HCl is 36.5 g/mol.

Hence, 71 g of chlorine gas gives 73 g of HCl. Then, the mass of HCl produced from 454.4 g of chlorine gas is calculated as follows:

mass of HCl = (454.4 × 73) / 71

                     = 467.2 g.

Therefore, the mass of HCl produced from 454.4 g of chlorine gas is 467.2 g.

If I have an unknown quantity of gas at a pressure of 204.83 kPa, a volume of 27.88 liters, and a temperature of 8.76°C , how many moles of gas do I have?​

Answers

Um what this answer is but I think 1.26

Answer:

700

Explanation:

How to find

Multiply the volume and pressure and divide the product by the temperature and the molar gas constant to calculate the moles of the hydrogen gas.

Solve: 204.83 × 27.88 / 8.76 = 651.901872146

Which is 651.90

In the nearest hundredths, the moles of gas is 700

How many grams of CaCl2 should be dissolved in 445.2 mL of water to make a 0.19 M solution of CaCl2?

Answers

In order to solve this, you will need to know how many moles of CaCl2 you will need, and to do so, you must look at the concentration of the solution.

You are told that the concentration of the solution is 0.19M, meaning that there is 0.19 moles of CaCl2 for every 1 liter of solution. However, you don't have 1 liter of solution, you have 445.2 mL. You must convert this to liters by dividing by 1000.

445.2 mL *  (1 L / 1000 mL) = 0.4452 L

Now, you can solve for how many moles the solution must have. Since M = mol / L and you are given M and L, you can set up an equality as follows:

0.19M = mol / 0.4452 L

Now, in order to find the number of moles, you multiply both sides by 0.4452L

0.19M * 0.4452 L = moles = 0.084588mol  

Now, you must calculate the molar mass of CaCl2 by using the periodic table

MM Ca = 40.078 g/mol

MM Cl = 35.452 g/mol

40.078 + (35.452 * 2) = 110.982 g/mol

Now you multiply the number of moles in the solution you calculated by the molar mass.

0.084588mol * 110.982 g/mol = 9.387 g CaCl2

Given : Pressure = 1.0 atm,      no. of moles = 0.85 mol

Temperature = [tex]25^{o}C = (25 + 273) K = 298 K[/tex]

According to the ideal gas equation, formula used is as follows.

PV = nRT

where,

P = pressure

V = volume

n = no. of moles

R = gas constant = 0.0821 L atm/mol K

T = temperature

Substitute the values into above formula as follows.

[tex]PV = nRT\\1.0 atm \times V = 0.85 mol \times 0.0821 Latm/mol K \times 298 K\\V = 21 L[/tex]

8.0 mol of methane gas reacts completely in a 2.00L container containing excess O2 in 3.2s. Find average rate of consumption of methane

Answers

Answer:

1.3 M/s

Explanation:

Step 1: Given data

Initial amount of methane (ni): 8.0 molFinal amount of methane (nf): 0 mol (it reacts completely)Volume of the container (V): 2.00 LTime elapsed (t): 3.2 s

Step 2: Calculate the average rate of consumption of methane

Methane burns in excess oxygen according to the following equation.}

CH₄ + 2 O₂ ⇒ CO₂ + 2 H₂O

We can calculate the average rate of consumption of methane (r) using the following expression.

r = - Δn/V × t = - (nf- ni) / V × t

r = - (0 mol - 8.0 mol) / 2.00 L × 3.2 s = 1.3 M/s

how much heat is required to increase the temperature of 20 grams of water by 26 degrees celsius?

Answers

Answer: 2175.68 J heat is required to increase the temperature of 20 grams of water by 26 degrees celsius.

Explanation:

Given: Mass = 20 g

Change in temperature = [tex]26^{o}C[/tex]

The standard value of specific heat of water is [tex]4.184 J/ g^{o}C[/tex]

Formula used to calculate the heat energy is as follows.

[tex]q = m \times C \times \Delta T[/tex]

where,

q = heat energy

m = mass of substance

C = specific heat of substance

[tex]\Delta T[/tex] = change in temperature

Substitute the values into above formula as follows.

[tex]q = m \times C \times \Delta T\\= 20 g \times 4.184 J/g ^{o}C \times 26^{o}C\\= 2175.68 J[/tex]

Thus, we can conclude that 2175.68 J heat is required to increase the temperature of 20 grams of water by 26 degrees celsius.

Answers

Answer:

5.12 m³

Explanation:

Using the combined gas law formula as follows:

P1V1/T1 = P2V2/T2

Where;

P1 = initial pressure (atm)

P2 = final pressure (atm)

V1 = initial volume (m³)

V2 = final volume (m³)

T1 = initial temperature (K)

T2 = final temperature (K)

According to this question;

V1 = 5.0 m³

V2 = ?

P1 = 0.84 atm

P2 = 0.89 atm

T1 = 298 K

T2 = 323 K

Using

P1V1/T1 = P2V2/T2

0.84 × 5/298 = 0.89 × V2/323

4.2/298 = 0.89V2/323

Cross multiply

4.2 × 323 = 298 × 0.89V2

1356.6 = 265.22V2

V2 = 1356.6 ÷ 265.22

V2 = 5.12 m³

Explanation:

To solve this question we must know that, to find the amount of atoms of a substance from its mass, we have, as first, to convert this mass to moles using molar mass of the substance. With the moles we can find the amount of molecules using Avogadro's number. And with the formula we can know the atoms presents:

Moles Fluorine (F₂, Molar mass: 37.997g/mol)

5.3g * (1mol / 37.997g) = 0.139 moles F₂

The pH of a solution with a Hydronium (H30+) ion concentration of 0.001M is

Answers

Answer:

The pH of a solution with a Hydronium (H₃O⁺) ion concentration of 0.001 M is 3.

Explanation:

pH, short for Hydrogen Potential, is a measure used to establish the level of acidity or alkalinity of a solution.

pH indicates the amount of hydrogen ions present in a solution or substance. Mathematically the pH is the negative logarithm of the molar concentration of hydrogen ions or protons (H⁺) or hydronium ions (H₃O⁺).

pH= - log [H⁺]= - log [H₃O⁺]

The pH scale goes from 0 to 14. Values ​​less than 7 indicate the range of acidity and those greater than 7 indicate alkalinity or basicity. The value 7 is considered neutral.

In this case, [H₃O⁺]= 0.001 M.

Replacing in the definition of pH:

pH= - log (0.001 M)

Solving:

pH= 3

The pH of a solution with a Hydronium (H₃O⁺) ion concentration of 0.001 M is 3.
