Suppose you have 9.0 mol of NH3 and 11.0 mol of O2 in a reactor. What would be the limiting reactant

Answers

Answer 1

The given reaction can be balanced as follows:\(4NH₃ +3 O₂ ⇒ 2N₂ + 6 H₂O\)

4 moles of ammonia reacts with 3 moles of O₂ . Then, 3.77 moles of NH₃ requires 2.52 moles.

The balanced chemical equation of a reaction is represents the perfect stoichiometry of all reactants and products. The number of each elements in the reactant side must be equal to their number in the product side.

The reaction between ammonia and oxygen can be written as:

4NH₃ +3 O₂ ⇒ 2N₂ + 6 H₂O.

Here, 4 moles of ammonia reacts with 3 mole of molecular oxygen to give 2 moles of nitrogen gas and 6 moles of water.

Then, number of moles of oxygen gas required to react completely with 3.77 moles of ammonia is :

(3.77 ×3)/4 = 2.52 moles.

Hence, the number of moles of O₂  corresponds 3.77 moles of NH₃  is 2.52 moles.

One of the most frequent methods of exposure to beryllium is:
a. Workers' inhalation of beryllium in the meat packing industry
b. Via wounds in the skin
c. Via direct skin contact
d. Through ingestion
e. Workers' inhalation of beryllium in metal processing industries

Answers

One of the most frequent methods of exposure to beryllium is through e. workers' inhalation of beryllium in metal processing industries. Beryllium is commonly used in various industrial processes, such as metal machining, foundry work, and alloy production.

During these activities, fine particles or fumes containing beryllium can be generated and released into the air.

Inhalation of airborne beryllium particles is considered the primary route of exposure in occupational settings. Workers who are involved in tasks that generate beryllium-containing dust or fumes may inhale these particles, which can enter the respiratory system and potentially reach the lungs. Once inhaled, beryllium can pose a health risk and may lead to the development of lung diseases, such as chronic beryllium disease (CBD).

While other routes of exposure to beryllium, such as direct skin contact or ingestion, are possible, they are generally less frequent compared to inhalation in occupational settings. Direct skin contact or ingestion of beryllium may occur in certain situations, such as handling beryllium-containing materials without proper protective measures or accidental ingestion of contaminated substances. However, the primary concern for exposure to beryllium remains through inhalation in metal processing industries where beryllium is utilized.

quizlet If the reaction between H2 and I2 to form HI were at equilibrium and an additional 0.25 moles of H2 were added to the reaction, what would happen

Answers

When additional 0.25 moles of H2 are added to the reaction at equilibrium, the equilibrium would shift to the right to relieve the stress caused by the increase in H2 concentration.

According to Le Chatelier's principle, the system would respond by favoring the forward reaction to restore equilibrium. This means that more HI would be formed from the excess H2 and I2. As a result, the concentrations of H2 and I2 would decrease, while the concentration of HI would increase. The reaction would continue until a new equilibrium is reached. Note that the extent of the shift and the change in concentrations depend on the reaction's equilibrium constant and stoichiometry.

what is the significance of finding archean ""redbeds"" or banded iron formations (bifs) during the evolution of the atmosphere?

Answers

This significant change in the Earth's atmosphere is marked by the emergence of redbeds, sediments that contain oxidised iron.

The release of oxygen into the atmosphere led to the formation of minerals on land (continental redbeds). Since the created oxygen was absorbed by rocks for a very long time, as seen in Banded Iron Formations (BIFs) and continental red beds, it did not accumulate in the atmosphere for very long. The majority of the oxygen created over time is still preserved in the historic "banded rock" and "red bed" formations. The growth of oxygen may have been significantly influenced by the oxidation of the mantle rocks. It has been suggested that the shift from subaerial to mostly submerged volcanoes may also have resulted in a decline in volcanic emission of decreased gases.

1. Cooking oil has a density of 0.526 grams per cubic centimeter (g/cm3). A block
has a mass of 20 grams (g) and a volume of 44 cubic centimeters (cm3).What will
happen when the object is placed into cooking oil? *

Answers

Answer:

The block floats

Explanation:

Density is the amount of matter contained in an object compared to its volume. It is the ratio of mass to volume. The SI unit of density is kg/m³. The formula of density is:

Density = mass / volume

An object floats when placed in a liquid if its density is less than that of the liquid and sinks if its density is greater than that of the liquid.

The cooking oil has a density = 0.526 g/cm³

The density of block = mass / volume = 20 g / 44 cm³ = 0.4545 g/cm³

Since the density of the block is less than that of the cooking oil, the block will float when placed into the cooking oil.

what is the mass of 0.85 of moles of CA (OH)2​

Answers

Considering the definition of molar mass, tthe mass of 0.850 moles of Ca(OH)₂ is 62.9 grams.

Definition of molar mass

The molar mass of substance is a property defined as the amount of mass that a substance contains in one mole.

The molar mass of a compound is the sum of the molar mass of the elements that form it multiplied by the number of times they appear in the compound.

Molar mass of Ca(OH)₂

In this case, you know the molar mass of the elements is:

Ca= 40 g/moleO= 16 g/moleH= 1 g/mole

So, the molar mass of the compound Ca(OH)₂ is calculated as:

Ca(OH)₂= 40 g/mole + 2× (16 g/mole + 1 g/mole)

Solving:

Ca(OH)₂= 74 g/mole

The molar mass of Ca(OH)₂ is 74 g/mole.

Mass of 0.850 mol Ca(OH)₂

You can apply the following rule of three: If by definition of molar mass 1 mole of the compound contains 74 grams, 0.850 moles of the compound contains how much mass?

mass= (0.850 moles× 74 grams)÷1 mole

mass= 62.9 grams

a) The theoretical yield of H2O is 16.25 grams.

b) The actual yield of H2O is 13.81 grams

The Propane Combustion Yield.

First, balance the equation

C3H8 + SO2 → 3CO2 + 4H2O

a) To calculate the theoretical yield of H2O when starting with 10 grams of C3H8, we first need to determine the limiting reagent. This is the reactant that will be completely consumed in the reaction, thereby limiting the amount of product that can be formed.

The molar mass of C3H8 is 44.1 g/mol,

so 10 grams of C3H8 is equivalent to 10/44.1 = 0.226 moles of C3H8.

The molar mass of SO2 is 64.1 g/mol. We don't know how much SO2 we have, so we need to use stoichiometry to determine the amount required to react with 0.226 moles of C3H8.

From the balanced equation, we can see that the molar ratio of C3H8 to SO2 is 1:1.

Therefore, we need 0.226 moles of SO2 to react with 0.226 moles of C3H8.

The molar ratio of H2O to C3H8 is 4:1.

So if 0.226 moles of C3H8 react, we can expect to produce 4 times as many moles of H2O.

The molar mass of H2O is 18.0 g/mol, so the theoretical yield of H2O is:

0.226 mol C3H8 × 4 mol H2O/mol C3H8 × 18.0 g/mol H2O

= 16.25 g H2O

Therefore, the theoretical yield of H2O is 16.25 grams.

b) If the actual yield of H2O is 85% of the theoretical yield, then the actual amount of H2O produced is:

0.85 × 16.25 g = 13.81 g

Therefore, the actual yield of H2O is 13.81 grams.

The resulting solution made from the combination of 50 ml of 1.0 M LiOH with 50 ml of 1.0 M HBr will be identical in all respects to 100 ml of 0.5 M LiBr.

What is Molarity ?

Molarity (M) is defined as the number of moles of solutes dissolved in 1L of solution. Molarity is also known as Molar concentration. The S.I unit of Molarity is molar (M) or mol/L.

It is expressed as:

Molarity = \(\frac{\text{Number of moles}}{\text{Volume (in L)}}\)

Number of moles = Molarity × Volume

Moles of LiOH = 1.0 × 0.05         [1 ml = 0.001 L]

                        = 0.05 mol

Moles of HBr = 1.0 × 0.05         [1 ml = 0.001 L]

                      = 0.05 mol

Now put the values in above formula we get

Molarity = \(\frac{\text{Number of moles}}{\text{Volume (in L)}}\)

             = \(\frac{0.05}{0.1}\)

             = 0.5 M LiBr

The mechanism of the 1,2-dibromopropane double elimination process with two equivalents of sodium amide.

The reaction mechanism begins with the deprotonation of one of the beta-carbons of 1,2-dibromopropane by sodium amide. This forms a carbanion intermediate that is stabilized by the electron-withdrawing effect of the two bromine atoms.

Next, a second equivalent of sodium amide deprotonates the other beta-carbon, forming another carbanion intermediate. The two carbanions then undergo an E2 elimination reaction, in which the bromine atoms are eliminated as bromide ions and a carbon-carbon double bond is formed.

the molar solubility for magnesium hydroxide, mg(oh)2, is 1.6x 104. calculate its ksp.

Answers

The Ksp of magnesium hydroxide is 4.096x10^12.

he Ksp (solubility product constant) of magnesium hydroxide (Mg(OH)2) can be calculated using the molar solubility value given.

The balanced equation for the dissociation of magnesium hydroxide is:

Mg(OH)2(s) ⇌ Mg2+(aq) + 2OH-(aq)

The molar solubility of Mg(OH)2 is given as 1.6x10^4. Since Mg(OH)2 dissociates into one Mg2+ ion and two OH- ions, the equilibrium concentrations can be expressed as follows:

[Mg2+] = x

[OH-] = 2x

The Ksp expression for Mg(OH)2 is then:

Ksp = [Mg2+][OH-]^2 = x * (2x)^2 = 4x^3

Substituting the molar solubility value into the expression:

Ksp = 4(1.6x10^4)^3 = 4.096x10^12

Therefore, the Ksp of magnesium hydroxide is 4.096x10^12.

The Ksp value represents the equilibrium constant for the dissociation of a sparingly soluble salt. It indicates the extent to which the salt dissociates into its constituent ions in a saturated solution at equilibrium. In the case of magnesium hydroxide, a high Ksp value suggests that it has a significant degree of dissociation and is relatively soluble in water.

Answers

The amount of CaCO₃ that will dissolve in the solution is 2.43 × 10⁻⁶ g (in scientific notation).

The balanced equation for the dissolution of CaCO₃ in water is:

CaCO₃(s) ↔ Ca₂+(aq) + CO₃²⁻(aq)

The solubility product expression for CaCO₃ is:

Ksp = [Ca²⁺][CO₃²⁻]

The problem provides the following information:

- Volume of Ca(NO₃)₂ solution = 2.70 × 10^2 mL = 0.270 L

- Concentration of Ca(NO₃)₂ solution = 0.0460 M

- Ksp of CaCO₃ = 8.70 × 10^-9

To determine the amount of CaCO₃ that will dissolve in the solution, we need to calculate the concentration of Ca₂+ ions in the solution using the concentration of Ca(NO₃)₂:

[Ca₂⁺] = 2 × [NO₃⁻] = 2 × 0.0460 M = 0.0920 M

Now we can use the Ksp expression to calculate the concentration of CO₃²⁻ ions in the solution:

Ksp = [Ca₂⁺][CO₃²⁻]

[CO₃²⁻] = Ksp/[Ca₂⁺] = (8.70 × 10^-9)/(0.0920 M) = 9.46 × 10^-8 M

Finally, we can use the concentration of CO₃²⁻to calculate the amount of CaCO₃ that will dissolve in the solution:

[CO₃²⁻] = [CaCO₃] (assuming complete dissociation)

[CaCO₃] = [CO₃²⁻] = 9.46 × 10^-8 M

The molecular weight of CaCO₃ is 100.1 g/mol. To convert from moles to grams, we multiply by the molecular weight:

m(CaCO₃) = [CaCO₃] × V × MW(CaCO₃)

m(CaCO₃) = (9.46 × 10^-8 mol/L) × (0.270 L) ×(100.1 g/mol) =2.43 × 10^-6 g

Estimate the average air pressure in a hole 500 meters below sea
Level.

Answers

Answer:

The average air pressure at sea level is approximately 51,181.25 hPa

Explanation:

Air pressure decreases with increasing altitude, and at a rate of about 1 hPa per 8.5 meters of elevation gain.

Therefore, to estimate the average air pressure in a hole 500 meters below sea level, we need to account for the increase in pressure due to the weight of the water column above the hole. The pressure due to the weight of a column of water is about 1 atm per 10 meters of depth.

So at a depth of 500 meters below sea level, the pressure due to the weight of the water column alone would be approximately:

(500 meters / 10 meters per atm) * 1 atm = 50 atm

Adding this to the atmospheric pressure at sea level, we can estimate the average air pressure at a depth of 500 meters below sea level as:

1013.25 hPa + (50 atm * 1013.25 hPa per atm) = 51,181.25 hPa

Therefore, the estimated average air pressure in a hole 500 meters below sea level is about 51,181.25 hPa.
