Enantiomers and diastereomers are two types of stereoisomers, which are molecules that have the same molecular formula and connectivity but differ in their three-dimensional arrangement of atoms in space. Enantiomers are mirror images of each other and cannot be superimposed on each other, like a left and right hand. They have identical physical and chemical properties, except for the way they interact with polarized light.

Enantiomers rotate plane-polarized light in opposite directions and are therefore called optical isomers. Diastereomers, on the other hand, are stereoisomers that are not mirror images of each other and can be distinguished by their physical and chemical properties. Unlike enantiomers, diastereomers do not rotate plane-polarized light in opposite directions. They have different melting and boiling points, solubilities, and reactivities.

Theoretical yield of iron (III) oxide is 4.92 g ; percent yield for this reaction is approximately 73.3%.

Quantity of a product obtained from reaction is expressed in terms of yield of the reaction. Amount of product predicted by stoichiometry is called theoretical yield and whereas amount obtained actually is called  actual yield.

Balanced chemical equation for the reaction is: 4Fe + 3O₂→ 2Fe₂O₃

Molar mass of Fe = 55.85 g/mol

So, Number of moles of Fe = mass/molar mass = 3.44 g/55.85 g/mol = 0.0615 mol

and Number of moles of Fe₂O₃ = 0.0615 mol Fe × (2 mol Fe₂O₃/4 mol Fe) = 0.0308 mol Fe₂O₃

Molar mass of Fe2O3 = 159.69 g/mol

Theoretical yield of Fe₂O₃ = number of moles × molar mass = 0.0308 mol × 159.69 g/mol = 4.92 g

Therefore, theoretical yield of iron (III) oxide is 4.92 g.

As percent yield = (actual yield / theoretical yield) x 100%

So, percent yield = (4.32 g / 5.89 g) x 100% ≈ 73.3%

Therefore,  percent yield for this reaction is approximately 73.3%.

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 substance B will have a higher boiling point.

When we talk about substances, they have different physical and chemical properties, such as melting point, boiling point, density, etc. These properties depend on different factors such as intermolecular forces, molecular mass, etc. The given question is asking about the boiling point of two different substances, one that has molecules that attract with London Dispersion attraction and the other with Dipole-Dipole attraction.

London Dispersion Attraction: London Dispersion force is a temporary attractive force that occurs between the atoms or molecules of nonpolar compounds. It is a type of Van der Waals force that arises due to instantaneous dipoles that arise in the electron clouds of the molecules. These forces are very weak and short-range.

Dipole-Dipole Attraction: Dipole-dipole attraction is an attractive force that occurs between the oppositely charged ends of polar molecules. This force is stronger than London dispersion forces because it involves two dipoles, and it is a long-range force.Now, to answer the question, we need to see which of these forces is stronger. We know that London Dispersion forces are weaker than Dipole-Dipole forces.

Therefore, substance B, which has molecules that attract with Dipole-Dipole attraction, will have a higher boiling point than substance A, which has molecules that attract with London Dispersion attraction. Thus, the boiling point of a substance depends on the type of intermolecular force it has.

The age of the muscovite crystal is 0.86 billion years.

We can use the half-life formula to determine the age of the muscovite crystal. The half-life formula is given as:

N = N₀ (1/2)^t/T

Where N is the remaining quantity of a substance, N₀ is the original quantity, t is the time that has passed, and T is the half-life of the substance.

Substituting the given values, we get:

N/N₀ = (1/2)^(2.2)T (N₀/2^2.2) = N

The age of the muscovite crystal is given by t, which we can calculate using the following formula:

t = T * log (N₀/N)

Substituting the values of N₀ and N, we get:

t = 1.3 * 10^9 * log (1/2^2.2)t = 1.3 * 10^9 * log (1/4.59479342)

In cellular respiration, one molecule of glucose (C6H12O6) is oxidized to produce energy in the form of ATP through a series of metabolic reactions, including the citric acid cycle.

During the citric acid cycle, acetyl-CoA, which is produced from the breakdown of glucose in earlier steps of cellular respiration, enters the cycle and reacts with oxaloacetate to form citrate. Through a series of enzymatic reactions, citrate is eventually converted back to oxaloacetate, producing CO2, NADH, FADH2, and ATP in the process.

For each glucose molecule oxidized by cellular respiration, two molecules of pyruvate are produced during glycolysis. Each pyruvate molecule then enters the mitochondria and is converted to one molecule of acetyl-CoA, which enters the citric acid cycle. Therefore, for each glucose molecule oxidized, two molecules of acetyl-CoA enter the citric acid cycle.

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.
