Identify the limiting reactant when 45.25 grams of nitrogen react with 52.5 liters of hydrogen at standard temperature and pressure to produce ammonia gas (NH3), which is used as a popular refrigerant. How many liters of ammonia is actually produced?

Answers

To identify the limiting reactant, we need to compare the amount of each reactant to the balanced chemical equation. The balanced equation for the reaction between nitrogen and hydrogen to produce ammonia is:

N2 + 3H2 → 2NH3

From the equation, we can see that one mole of nitrogen reacts with three moles of hydrogen to produce two moles of ammonia.

First, let's convert the mass of nitrogen to moles:

45.25 g N2 x (1 mol N2/28.02 g N2) = 1.612 mol N2

Next, let's convert the volume of hydrogen to moles using the ideal gas law:

PV = nRT

n = PV/RT

n = (52.5 L) (1 atm) / (0.0821 L·atm/mol·K) (273 K) = 2.19 mol H2

How many liters of ammonia is actually produced?

Now we can compare the number of moles of each reactant to see which is limiting:

N2 : H2 = 1.612 mol : 2.19 mol

According to the balanced equation, one mole of nitrogen reacts with three moles of hydrogen. So we need 4.836 moles of hydrogen to completely react with 1.612 moles of nitrogen. However, we only have 2.19 moles of hydrogen, which means it is the limiting reactant.

Therefore, the amount of ammonia that can be produced is limited by the amount of hydrogen available.

The balanced equation shows that 3 moles of hydrogen produces 2 moles of ammonia. So, with 2.19 moles of hydrogen, we can produce:

2.19 mol H2 x (2 mol NH3/3 mol H2) = 1.46 mol NH3

Now, let's convert the moles of ammonia to liters using the ideal gas law:

PV = nRT

V = nRT/P

V = (1.46 mol) (0.0821 L·atm/mol·K) (273 K) / (1 atm) = 31.2 L

Therefore, 31.2 liters of ammonia gas can be produced from the given amount of nitrogen To identify the limiting reactant, we need to compare the amount of each reactant to the balanced chemical equation. The balanced equation for the reaction between nitrogen and hydrogen to produce ammonia is:

What is the amount of pure substance in 10. 7 g of aluminum? Assume the molar mass of aluminum is 26. 98 g/mol

Answers

This is calculated by dividing the mass of aluminum (10.7 g) by its molar mass (26.98 g/mol), resulting in 0.395 mol.

To find the amount of pure substance (in moles) in 10.7 g of aluminum, we need to divide the given mass by the molar mass of aluminum.

The molar mass of aluminum is given as 26.98 g/mol.

Therefore, the amount of pure substance (in moles) in 10.7 g of aluminum can be calculated as:

moles = mass/molar mass

moles = 10.7 g/26.98 g/mol

moles = 0.396 moles (rounded to three significant figures)

So, there are approximately 0.395 moles of pure substance (aluminum) in 10.7 g of aluminum.

a gas has a mass of 3175 g and takes up enough space to fill a room that is 2.00 m x 2.00 m x 5.00 m determined what the gas is in g/mL

Answers

To determine the gas in g/mL, we need to calculate the volume of the gas first. We can use the formula for the volume of a rectangular room to find the volume of the room:

Volume = length x width x height = 2.00 m x 2.00 m x 5.00 m = 20.00 m³

Next, we need to convert the mass of the gas from grams to kilograms, since density is usually expressed in units of kg/m³. We can do this by dividing the mass by 1000:

Mass = 3175 g ÷ 1000 = 3.175 kg

Finally, we can calculate the density of the gas using the formula:

Density = Mass ÷ Volume

Density = 3.175 kg ÷ 20.00 m³ = 0.1588 kg/m

To convert the density from kg/m³ to g/mL, we need to multiply by 1000 and then divide by 1000:

Density = 0.1588 kg/m³x 1000 g/kg ÷ 1000 mL/L = 0.1588 g/mL

Therefore, the gas has a density of 0.1588 g/mL. Without additional information, we cannot determine the identity of the gas.

The molar mass of a compound is the mass of one mole of the compound and is expressed in grams per mole (g/mol). To calculate the molar mass of a compound, we sum the atomic masses of all the atoms in the compound.

For NO₂, we have:

Molar mass of N = 14.01 g/mol

Molar mass of O = 16.00 g/mol

Therefore, the molar mass of NO₂ = 14.01 g/mol + 2(16.00 g/mol) = 46.01 g/mol.

Calculate the pH of a solution prepared by dissolving 1. 60 g of sodium acetate, CH3COONa, in 92. 00 mL of 0. 10 M acetic acid, CH3COOH(aq). Assume the volume change upon dissolving the sodium acetate is negligible. Ka of CH3COOH is 1. 75 x 10^-5. ​

Answers

The solution's pH value is 5.08.

To solve this problem, we need to use the principles of acid-base chemistry and the equilibrium constant expression for the dissociation of acetic acid (CH₃COOH) to its conjugate base, acetate (CH₃COO⁻).

First, we need to calculate the concentration of acetic acid in the solution. Since the initial concentration of acetic acid is given as 0.10 M and the volume of the solution is 92.00 mL, we can calculate the number of moles of acetic acid as follows:

moles of acetic acid = 0.10 M x 0.0920 L = 0.00920 moles

Next, we need to calculate the number of moles of sodium acetate in the solution. The molar mass of sodium acetate is 82.03 g/mol, so we can convert the mass of sodium acetate to moles as follows:

moles of sodium acetate = 1.60 g / 82.03 g/mol = 0.0195 moles

Since sodium acetate dissociates completely in water to produce acetate ions and sodium ions, the concentration of acetate ions in the solution is equal to the number of moles of sodium acetate divided by the total volume of the solution:

acetate ion concentration = moles of sodium acetate / total volume of solution

acetate ion concentration = 0.0195 moles / 0.0920 L = 0.212 M

Now we can use the equilibrium constant expression for the dissociation of acetic acid to calculate the pH of the solution:

Ka = [H⁺][CH₃COO-]/[CH₃COOH]

Since we are assuming that the concentration of acetic acid is still 0.10 M, and we now know that the concentration of acetate ions is 0.212 M, we can rearrange the equation and solve for [H⁺]:

[H⁺] = (Ka x [CH₃COOH])/[CH₃COO-]

[H⁺] = (1.75 x 10⁻⁵ x 0.10)/0.212

[H⁺] = 8.23 x 10⁻⁶ M

Finally, we can calculate the pH of the solution using the equation:

pH = -log[H⁺]

pH = -log(8.23 x 10⁻⁶)

pH = 5.08

Therefore, the pH of the solution is 5.08.

silver sulfide (ag2s) is the common tarnish on silver objects. what mass of silver sulfide can be made from 1.53 x 10-3g of hydrogen sulfide (h2s) obtained from a rotten egg?\

Answers

Silver sulfide (Ag2S) is the common tarnish on silver objects. The mass of silver sulfide that can be made from 1.53 x 10^-3g of hydrogen sulfide (H2S) obtained from a rotten egg is 3.67 g.

Let's understand this in detail:

The balanced chemical equation for the reaction is:

2 AgNO3 + H2S → Ag2S + 2 HNO3

The molar mass of H2S is 34.08 g/mol.

1.53 x 10^-3g of H2S = (1 mol / 34.08 g) * (1.53 x 10^-3g) = 4.49 x 10^-5 mol H2S.

From the balanced equation, it is clear that one mole of Ag2S is formed from one mole of H2S.

Therefore, the number of moles of Ag2S formed from 1.53 x 10^-3g of H2S is 4.49 x 10^-5 mol.

The molar mass of Ag2S is 247.8 g/mol. Therefore, the mass of Ag2S formed from 1.53 x 10^-3g of H2S is

(247.8 g/mol) * (4.49 x 10^-5 mol) = 0.0111 g or 11.1 mg.

To convert to grams, divide by 1000:11.1 mg ÷ 1000 = 0.0111 g or 11.1 mg = 1.11 x 10^-2

Therefore, the mass of silver sulfide that can be made from 1.53 x 10^-3g of hydrogen sulfide obtained from a rotten egg is 3.67 g (approx).

Answers

Answer:

After neutralizing the sodium hydroxide solution with hydrochloric acid, the student should remove any excess hydrochloric acid and water from the solution to obtain a pure solution of sodium chloride. This can be done by a process called evaporation or by using a separating funnel.

To prepare a pure solution of sodium chloride, the student should follow the steps below:

Transfer the neutralized solution of sodium chloride into an evaporating dish.

Heat the evaporating dish over a low flame, stirring continuously until all the water evaporates.

Once all the water has evaporated, the student will be left with a dry residue of sodium chloride in the evaporating dish.

The sodium chloride can then be transferred to a clean, dry container and stored for use.

Alternatively, the student can use a separating funnel to remove excess hydrochloric acid and water from the solution. In this case, the neutralized solution is transferred to a separating funnel, and an equal volume of water is added. The funnel is then shaken, and the two layers are allowed to separate. The bottom layer containing the excess hydrochloric acid is drained off, leaving behind a pure solution of sodium chloride.

question 5 options:

540 ppm

220 ppm

260 ppm

Can anyone help me answer these 2 questions ?

Answers

Answer:

1. is "It produces sodium carbonate, a bitter metallic-tasting compound."
2. is 6:1

Explanation:

1. While baking powder does produce sodium bicarbonate or at least plays a part in creating sodium bicarbonate, its alkaline nature allows the dish or the reaction to avoid tasting metallic.

2. 6:1 because logically the more water there is in the flour, the less viscous it would be.

Propylene glycol, C3H6(OH)2, is sometimes used in automobile antifreeze solutions. If an aqueous solution has
a mole fraction XC₂H(OH)₂ = 0.100, calculate (a) the percent propylene glycol by mass; (b) the molality of the
propylene glycol in the solution.

Answers

Molality is 10.8m, Freezing point is -09.8c ,Certain pharmaceuticals, cosmetics, or food products use it to preserve moisture by absorbing more water.

Can propylene glycol hurt people?

The U.S. Food and Drug Administration (FDA) has deemed propylene glycol to be "generally regarded as safe," and it believes a daily food intake of 23 mg/kg of body weight to be safe for people ages 2-65. Propylene glycol can be found in a variety of foods, cosmetics, and medication.

Is propylene glycol skin-safe?

A humectant is a substance that is added to cosmetics to promote the retention of moisture in the skin and hair. Propylene glycol falls under this category. Propylene glycol is well accepted by skin and shouldn't irritate or produce redness.

YOU DO:
1) Hydrogen and iodine gases where placed into a 1.00 liter container, and allowed to reach equilibrium at
time = 2. The reaction is: H₂(g) + 12 (8) = 2 HI (8)
Time = 2
Time = 3
Time=0
Time = 1
A) Complete the box for time = 1, when one of the H₂ has reacted.
B) Complete the box for time = 3, after the reaction has reached equilibrium.
C) Between time = 1 and time = 2, which reaction is favored, the forwards or reverse reaction?

Answers

At time = 1, one of the H₂ molecules has reacted, producing one molecule of HI. This means that there are now 0.5 moles of H₂, 0.5 moles of I₂, and 1 mole of HI in the container.

What does B indicates?

At time = 3, the reaction has reached equilibrium. This means that the concentrations of all three gases have stabilized. Without additional information about the reaction conditions and equilibrium constants, we cannot determine the exact concentrations of each gas at equilibrium.

What does C indicates?

Between time = 1 and time = 2, the forwards reaction (H₂ + I₂ → 2HI) is favored because one of the H₂ molecules has reacted to produce HI. This means that the concentration of H₂ has decreased while the concentration of HI has increased, driving the reaction forwards according to Le Chatelier's principle.

A1 L sample from Tempe Town lake has a pH of 3. 57. Exhaust from cars on nearby highways

often mixes with rain to form HNO3. Use this information to answer the following questions.

1. What is the concentration of H+ ions in the sample?

2. If it took 80 ml of 1 M NaOH to neutralize 250 ml of the acidic solution, what is the

molarity of HNO3 in the sample?

3. How many moles of HNO3 are in the

solution?

Answers

Answer:

see explanations

Explanation:

1. pH = -log [H+]

so [H+] = 10^(-pH) = 10^(-3.57) = 2.7 x 10^(-4) M

2. neutralize implies mol acid = mol base

so [HNO3] = (1 M) * (0.080 L) / (0.250 L) = 0.32 M HNO3

3. mol HNO3 = molarity of HNO3 * volume of HNO3

= 0.32 M HNO3 * 0.250 L HNO3 = 0.080 mol HNO3

Example: Ba8Mu7
Beanium shroomium
Beanium shroomide
Octabeanium heptashroomide
