I apologize, but as an AI text-based model, I don't have direct access to specific external data resources such as ALEKS.

However, I can provide you with some general information about the solubility of AgBr and how to approach this problem.

The solubility of a compound, such as AgBr, refers to the maximum amount of that compound that can dissolve in a given amount of solvent at a particular temperature.

The solubility of AgBr can be affected by the presence of other substances in the solvent, such as ammonia (NH3) in this case.

To calculate the solubility of AgBr, you need to know its solubility product constant (Ksp) at 25°C.

The Ksp is an equilibrium constant that represents the product of the concentrations of the dissolved ions raised to the power of their stoichiometric coefficients. Unfortunately, I don't have access to the specific Ksp value for AgBr.

However, I can provide you with a general approach to solving this problem. Assuming you have the Ksp value for AgBr, you can set up the following equilibrium equation:

AgBr(s) ⇌ Ag⁺(aq) + Br⁻(aq)

The Ksp expression for this equilibrium is:

Ksp = [Ag⁺][Br⁻]

At equilibrium, the concentration of Ag⁺ will be equal to the concentration of Br⁻ since they have a 1:1 stoichiometric ratio.

For the solubility of AgBr in pure water, you can assume that the initial concentrations of Ag⁺ and Br⁻ are both zero. Let's say the equilibrium concentration of Ag⁺ and Br⁻ is x M. Thus, you can express the Ksp equation as:

Ksp = x * x = x^2

Solve for x to find the solubility of AgBr in pure water.

For the solubility of AgBr in 0.35 M ammonia (NH3), you would need additional information, such as the formation constant of the Ag(NH3)2+ complex. The presence of ammonia can affect the solubility of AgBr by complexing with the silver ions and shifting the equilibrium.

Without the necessary data, it is challenging to provide an accurate calculation.

If you have access to the Ksp and formation constant values for AgBr and Ag(NH3)2+, I can assist you further in calculating the solubility of AgBr in 0.35 M ammonia.

The log mean of temperature difference (LMTD) is approximately 13.953°C.

To determine  the log mean temperature difference (LMTD) for a liquid-to-gas counterflow heat exchanger the following formula will be used:

LMTD = (ΔT1 - ΔT2) / ln(ΔT1 / ΔT2)

Where:

ΔT1  is the temperature difference at one end of the exchanger

ΔT2 is the temperature difference at the other end of the exchanger

The gas enters at 32°C and leaves at 18°C, while the liquid enters at 7°C and leaves at 15°C.

ΔT1 = (32°C - 15°C) = 17°C

ΔT2 = (18°C - 7°C) = 11°C

Here LMTD will be calculated:

LMTD = (17°C - 11°C) / ln(17°C / 11°C)

By using the given values and performing the calculations:

LMTD ≈ 6°C / ln(1.545)

LMTD ≈ 6°C / 0.430

LMTD ≈ 13.953°C

Therefore, log mean of temperature difference (LMTD) is approximately 13.953°C.

Answer:The mass of phosphorus in 75.

0 g of calcium monohydrogen phosphate is 32.0 g.

Explanation:

This is because calcium monohydrogen phosphate is a compound that is composed of calcium cations (Ca2+) and monohydrogen phosphate anions (H2PO4-). The chemical formula for this compound is Ca(H2PO4)2. Since phosphorus has an atomic weight of 31 g/mol, and calcium monohydrogen phosphate contains two phosphorus atoms for each mole, the mass of phosphorus in 75.0 g of calcium monohydrogen phosphate is 32.0 g.

Answer:  FeO2

Explanation:

 1.116       g  Fe

0.480     g O

We want to compare the NUMBER of Fe and O atoms.  We only have their masses, but since the molar mass of Fe is 5 times that of O, let's multiply the grams of O by 5 to have it "catch up" to the iron in ternms of number of atoms.   If the molar masses were the same, the masses would be in direct proportion to the formula.  Since they aren't, multiply by the molar mass ratio:

(1.116 grams Fe) x 1 = 1.116 g Fe

(0.480 g O) x 5 = 2.40 g O  [Changes the O mass into a number that correlates with the number of atoms relative to iron],

If the molar masses were the same, this would be the ratio of O to Fe atoms in the compound.  Normalize to the Fe number by dividing both by 1.116:

Fe = 1

O = 2.15

Not perfect, but an empiricle formula of FeO2 makes sense.  I don't see enough information here to prove that this is also the molecular formula, but FeO2 is a valid compound.  Fe(IV)O2,

1. The empirical formula of the compound is Fe₂O₃

2. The molecular formula of the compound is Fe₂O₃

1. Determination of the empirical formula of the compound.

Fe = 1.116 g

O = 0.480 g

Divide by their molar mass

Fe = 1.116 / 56 = 0.02

O = 0.480 / 16 = 0.03

Divide by the smallest

Fe = 0.02 / 0.02 = 1

O = 0.03 / 0.02 = 1.5

Multiply by 2 to express in whole number

Fe = 1 × 2 = 2

O = 1.5 × 2 = 3

Therefore, the empirical formula of the compound is Fe₂O₃

2. Determination of the molecular formula of the compound.

Empirical formula = Fe₂O₃

Molar mass = 5 × molar mass of O₂ = 5 × 32 = 160 g/mol

Molecular formula = empirical × n = molar mass

[Fe₂O₃]n = 160

[(2×56) + (3×16]n = 160

[112 + 48]n = 160

160n = 160

Divide both side by 160

n = 160 / 160

n = 1

Molecular formula = [Fe₂O₃]n

Molecular formula = [Fe₂O₃] × 1

The H-N-H angle in ammonia is smaller than the H-N-H angle in the ammonium ion due to the repulsion between the electrons in the NH4+ molecule and the tetrahedral geometry of the ammonium ion.

Ammonia (NH3) and ammonium ion (NH4+) have different geometries due to the presence of an additional hydrogen ion (H+) in the ammonium ion. The H-N-H angle in ammonia is approximately 107 degrees, while the H-N-H angle in the ammonium ion is approximately 109.5 degrees. This difference in the H-N-H angles can be explained by the following reasons:

1. Electron repulsion: In the ammonium ion, there is an extra hydrogen ion that carries a positive charge. This positive charge attracts the electrons in the NH4+ molecule, resulting in a smaller bond angle. As a result, the electron pairs are pushed closer together, which causes the H-N-H angle to increase slightly.

2. Tetrahedral geometry: The ammonium ion has a tetrahedral geometry, with four equivalent bonds and bond angles of approximately 109.5 degrees. This geometry is more stable and has lower energy than the trigonal pyramidal geometry of ammonia. The tetrahedral geometry of the ammonium ion is due to the sp3 hybridization of the nitrogen atom, which results in four hybrid orbitals that are oriented towards the four hydrogen atoms.

When the calorimeter is used to measure the enthalpy of a reaction, the system = contents and surroundings = calorimeter + air.

A calorimeter is a device used to measure the heat of chemical reactions or physical changes, as well as heat capacity. Among the most common types are differential scanning calorimeters, isothermal micro calorimeters, titration calorimeters, and accelerated rate calorimeters.

The system is the contents, and the calorimeter and air are the surroundings. Because heat can be absorbed or evolved when contents react. If heat is produced, the temperature of the calorimeter rises. Using this temperature change and the calorimeter's heat capacity, we can calculate the enthalpy of the reaction.

If the reaction absorbs heat, the temperature of the calorimeter falls, and we can calculate the enthalphy of the reaction. As a result, the system exchanges heat with the calorimeter and the surrounding air.

From this equation, we can see that the mole ratio of FeO to MgO is 1:1. This means that for every one mole of FeO, there is one mole of MgO involved in the reaction.

What is Mole?

In chemistry, a mole is a unit of measurement that represents an amount of substance. It is defined as the amount of a substance that contains the same number of entities (such as atoms, molecules, or ions) as there are atoms in 12 grams of carbon-12. This number is known as Avogadro's number and is approximately equal to 6.022 x 10²³ entities per mole.

The mole is used as a convenient way to express the amount of a substance in chemical reactions and calculations. For example, the stoichiometry of a chemical reaction is expressed in terms of mole ratios, which show the relative numbers of moles of reactants and products involved in the reaction. The concept of mole also allows us to convert between different units of measurement, such as grams and moles, using the molar mass of a substance.

The mole ratio of iron (II) oxide (FeO) and magnesium oxide (MgO) can be determined from the balanced chemical equation for the reaction between these two compounds. The balanced equation is:

FeO + MgO → Fe + Mg

From this equation, we can see that the mole ratio of FeO to MgO is 1:1. This means that for every one mole of FeO, there is one mole of MgO involved in the reaction.

The soda in a fridge has more thermal energy than the soda on the kitchen table.

Thermal energy is the total energy possessed by an object due to the motion of its particles. It is directly related to the temperature of the object. When a soda is placed in a fridge, it is exposed to a lower temperature environment. The fridge actively removes heat from the air inside, creating a cooler environment. As a result, the soda's temperature decreases. The decrease in temperature corresponds to a decrease in the average kinetic energy of the soda's particles, which directly affects its thermal energy.

On the other hand, a soda on the kitchen table is exposed to the surrounding room temperature. While the room temperature may vary depending on the location and climate, it is generally higher than the temperature inside a fridge. Consequently, the soda on the kitchen table has a higher temperature, which corresponds to a higher average kinetic energy of its particles and thus a higher thermal energy.

In summary, the soda in a fridge has more thermal energy than the soda on the kitchen table due to the lower temperature environment it is exposed to. The lower temperature corresponds to a decrease in the average kinetic energy of its particles and, consequently, a lower overall thermal energy.
