Answer 1

The mass of the excess reagent (iron) that remains after the reaction is complete is 12.1 grams.

The maximum mass of Iron(III) oxide that can be formed is 74.8 grams.

The formula for the limiting reactant is O₂, which is oxygen gas.

Calculate the number of moles of each reactant:

Number of moles of iron = 38.2 g / 55.845 g/mol = 0.683 moles

Number of moles of oxygen = 14.9 g / 32.00 g/mol = 0.466 moles

The balanced equation shows that the stoichiometric ratio between iron and oxygen is 4:3. Therefore, the mole ratio of iron to oxygen is 4:3.

Since the mole ratio of iron to oxygen is greater than 4:3, it means that there is an excess of iron and oxygen is the limiting reactant. So we need to use the number of moles of oxygen to calculate the maximum mass of Iron(III) oxide that can be formed.

The balanced equation shows that 1 mole of iron reacts with 1 mole of oxygen to produce 1 mole of Iron(III) oxide. The molar mass of Iron(III) oxide is 159.69 g/mol.

Number of moles of Iron(III) oxide = 0.466 moles (which is equal to the number of moles of oxygen)

The maximum mass of Iron(III) oxide = Number of moles of Iron(III) oxide x molar mass of Iron(III) oxide

Maximum mass of Iron(III) oxide = 0.466 moles x 159.69 g/mol = 74.8 grams

The maximum mass of Iron(III) oxide that can be formed is 74.8 grams.

The formula for the limiting reactant is O₂, which is oxygen gas.

To calculate the mass of the excess reagent (iron) that remains after the reaction is complete, we need to first calculate the mass of iron that reacted with the oxygen:

Mass of iron reacted = 0.466 moles x 55.845 g/mol = 26.1 grams

The initial mass of iron was 38.2 grams, so the mass of excess iron that remains after the reaction is complete is:

Mass of excess iron = initial mass of iron - a mass of iron reacted

Mass of excess iron = 38.2 g - 26.1 g = 12.1 grams

The mass of the excess reagent (iron) that remains after the reaction is complete is 12.1 grams.

Answers

The iupac name for the following compound is 3,6-dichloroaniline. Option d is correct choice.

The IUPAC name of a compound is a systematic name that follows a set of rules defined by the International Union of Pure and Applied Chemistry (IUPAC). In the case of the given compound with two chlorine atoms and an amino group attached to a benzene ring, the correct IUPAC name is based on the positions of the chlorine atoms relative to the amino group.

To name the compound, we need to number the carbons in the benzene ring starting from one of the carbons adjacent to the amino group. The positions of the two chlorine atoms are then indicated by their numbers, separated by a comma, before the name of the parent compound, which is "aniline" in this case.

By following this procedure, we can see that the correct IUPAC name for the compound is 3,6-dichloroaniline, as the chlorine atoms are located at positions 3 and 6 relative to the amino group. Hence option d is correct choice.

he partial pressure of carbon dioxide is 45 mm hg in the blood and 40 mm hg in the alveoli. what happens to the carbon dioxide?

Answers

b) It diffuses into the alveoli is the correct option. The gas goes from a higher partial pressure to a lower partial pressure along its own gradient.

The partial pressure of CO2 at the blood is thus 45 mm Hg and at the alveoli is 40 mm Hg. After then, CO2 travels from the blood to the alveoli. In this mechanism, CO2 cannot be broken down into carbon and oxygen. Compared to O2, CO2 is more soluble in blood. For CO2 diffusion, a very small partial pressure gradient is required. It just takes a 5-mmHg pressure gradient for CO2 gas to diffuse. Hence, CO2 will transfer from blood into alveoli.

calculate the ph of a solution that is 0.258 m nh2nh2 and 0.387 m nh2nh3cl. kb of nh2nh2 is 1.7 x 10-6.

Answers

The pH of the solution is 11.13.

First, let's write the balanced chemical equation for the reaction:

NH₂NH₂ + H₂O ↔ NH₂NH₃⁺ + OH⁻

The Kb expression for this reaction is,

Kb = [NH₂NH₃⁺][OH⁻] / [NH₂NH₂]

Since we're given the concentration of NH₂NH₂ and NH₂NH₃⁺, we can use the Kb expression to find [OH⁻]:

Kb = [NH₂NH₃⁺][OH⁻] / [NH₂NH₂]

1.7 × 10^-6 = (0.387-x)x / (0.258+x)

where x is the concentration of ion in mol/L.

Solving for x, we get:

x = 7.43 × 10^-4 M

Therefore, the concentration of OH⁻ ion in the solution is 7.43 × 10^-4 M. To find the pH of the solution, we can use the equation:

pH = 14 - pOH = 14 - (-log[OH⁻]) = 11.13.

a rather confused student, ina fogg, hydrolyzed the intermediate ester with 6 m hcl rather than 3 m naoh, and then she boiled the reaction mixture with 50% naoh instead of 6 m hcl. filtration of the cooled solution yielded only a little dimedone. finally realizing her mistake, she acidified the filtrate and a white solid precipitated, but its melting point was different from that of dimedone. what was this solid, and how did it form?

Answers

The white solid formed was likely a different compound due to the use of incorrect reagents and conditions during the reaction.

When an ester is hydrolyzed with HCl, the reaction typically proceeds via an acid-catalyzed mechanism, in which the ester is protonated to form a tetrahedral intermediate that quickly breaks down into a carboxylic acid and an alcohol. On the other hand, when an ester is hydrolyzed with NaOH, the reaction proceeds via a base-catalyzed mechanism, in which the ester is deprotonated to form a negatively charged intermediate that quickly breaks down into a carboxylate ion and an alcohol.

In this case, the student hydrolyzed the intermediate ester with 6 M HCl instead of 3 M NaOH. This likely led to the protonation of the intermediate and the formation of a carboxylic acid and an alcohol. The student then boiled the reaction mixture with 50% NaOH instead of 6 M HCl. This would have led to the deprotonation of the carboxylic acid and the formation of a carboxylate ion and an alcohol. However, since the NaOH concentration was much higher than what was needed for the reaction, it's possible that the reaction was not selective and other side reactions occurred as well.

consider a solution of two gases. what is the effect of withdrawing heat on the probability of a successful reaction, on a per-collision basis?

Answers

Withdrawing heat from a solution of two gases will lower the temperature, affecting the probability of a successful reaction on a per-collision basis.

When temperature decreases, the average kinetic energy of the gas molecules also decreases. Consequently, the molecules move slower, resulting in fewer collisions between them. This reduces the chances of successful reactions occurring during each collision.

Moreover, a lower temperature means that the energy barrier for a reaction, known as activation energy, becomes relatively higher compared to the average kinetic energy of the molecules. Activation energy is the minimum amount of energy required for a reaction to occur.

The reaction rate, which is the speed at which a reaction proceeds, is influenced by temperature. The Arrhenius equation, which quantifies the relationship between temperature and reaction rate, shows that a decrease in temperature results in a slower reaction rate.

the reaction rate constant is determined to be 0.012 m-1 s-1. if after 27 minutes the amount of a left is 0.048 m. what was the initial concentration of a?

Answers

The initial concentration of 'A' was approximately 1.371 M.

To determine the initial concentration of 'A' given the reaction rate constant, time, and the remaining amount of 'A', you can use the integrated rate law equation for a first-order reaction:

[A]t = [A]₀ * e^(-kt)

where:
[A]t = concentration of 'A' at time t (0.048 M)
[A]₀ = initial concentration of 'A'
k = reaction rate constant (0.012 M⁻¹ s⁻¹)
t = time in seconds (27 minutes = 27 * 60 = 1620 seconds)

Now, let's solve for [A]₀:

0.048 M = [A]₀ * e^(-0.012 M⁻¹ s⁻¹ * 1620 s)

To find [A]₀, divide both sides by e^(-0.012 * 1620):

[A]₀ = 0.048 M / e^(-0.012 * 1620)

Now, calculate the value:

[A]₀ ≈ 0.048 M / e^(-19.44)

[A]₀ ≈ 0.048 M / 0.000035

[A]₀ ≈ 1.371 M

So, the initial concentration of A was approximately 1.371 M.

Answers

The empirical formula of the compound is CH2O.

To find the empirical formula of the compound, we need to determine the ratios of the atoms in the compound. To do this, we need to find the number of moles of each element present in the compound.

The molar mass of carbon is 12.01 g/mol, the molar mass of hydrogen is 1.008 g/mol, and the molar mass of oxygen is 16.00 g/mol. The number of moles of carbon in the sample is:0.1565 g × 1 mol/12.01 g ≈ 0.0130 mol. The number of moles of hydrogen in the sample is:0.02627 g × 1 mol/1.008 g ≈ 0.0261 molThe number of moles of oxygen in the sample is:

0.4170 g × 1 mol/16.00 g ≈ 0.0261 mol

Now that we know the number of moles of each element, we can determine the simplest whole number ratio of the elements in the compound. We can do this by dividing each number of moles by the smallest number of moles. In this case, the smallest number of moles is 0.0130 mol.

We get:

Carbon: 0.0130 mol ÷ 0.0130 mol = 1

Hydrogen: 0.0261 mol ÷ 0.0130 mol = 2

Oxygen: 0.0261 mol ÷ 0.0130 mol = 2

Answers

As a result, a 1.6-mm-thick slice of graphite has 8 106 layers of graphene. The solution is 8.0 1006. We can use unit conversions to solve this problem.

1 picometer (pm) = 1 × 10^-12 meters (m)

Therefore, 200 picometers (200 pm) = 200 × 10^-12 meters (m)

To find the number of layers of graphene in a 1.6-mm-thick piece of graphite, we need to divide the thickness of the graphite by the thickness of one layer of graphene:

1.6 mm = 1.6 × 10^-3 meters (m)

Number of layers of graphene = thickness of graphite / thickness of one layer of graphene

does the freezing point depression equal the freezing point of pure solution minus the freezing point of the solution

Answers

No, the freezing point depression does not equal the freezing point of the pure solvent minus the freezing point of the solution.

The freezing point depression is defined as the difference between the freezing point of the pure solvent and the freezing point of the solution. In other words, it is the amount by which the freezing point of the solvent is lowered when a solute is added to it.

The freezing point depression is related to the concentration of the solute in the solution, as well as the properties of the solvent and solute. The greater the concentration of the solute, the greater the freezing point depression.

The relationship between freezing point depression, solute concentration, and solvent properties is described by the equation ΔTf = Kf·m, where ΔTf is the freezing point depression, Kf is the freezing point depression constant of the solvent, and m is the molality of the solute in the solution.

In summary, the freezing point depression is not equal to the freezing point of the pure solvent minus the freezing point of the solution, but rather the difference between the freezing point of the pure solvent and the freezing point of the solution, and is related to the concentration of the solute in the solution.
