How much iron can be recovered from 25. 0g of fe2o3.

An electron with a negative energy is attached to the nucleus by the attraction between its opposing charges. The closer it is to the nucleus, the more closely connected it is. The farther an electron is from the nucleus, the greater its energy. The correct option is B.

The electron's energy grows as it goes away from the nucleus and gets less and less negative. When the electron is not subject to the nucleus's attracting Coulomb attraction, it has zero potential energy and only kinetic energy, which is always positive. The electron has greater energy the further it travels.

On the other hand, the nucleus's weak forces of attraction hold electrons that are moving away from it.

Thus the correct option is B.

Charles's Law helps us understand the relationship between temperature and volume of a gas when other factors, such as pressure and number of moles, remain constant. The empirical gas law that describes the relationship between the volume and temperature of a gas when the number of moles and pressure are constant is Charles's Law.  

This can be expressed mathematically as: V₁/T₁ = V₂/T₂
Where V₁ and V₂ represent the initial and final volumes of the gas, and T₁ and T₂ represent the initial and final temperatures of the gas, respectively. The relationship can also be stated as: V/T = constant

To illustrate this law, let's consider an example. Imagine a balloon filled with a fixed number of moles of gas at a constant pressure. If we were to heat the balloon by placing it in a warm environment, the temperature of the gas inside the balloon would increase.

Answer: 392.71 g of O2 would be necessary to produce 221.3g of H2O

Explanation:

The question requires us to calculate the mass of oxygen gas (O2) necessary to produce 221.3g of H2O, given the following balanced equation:

The problem presented can be classified as a mass to mass stoichiometry problem. To solve it, we'll need to follow the steps:

mass of H2O → moles of H2O → moles of O2 → mass of O2

First, let's determine the number of moles of H2O contained in 221.3g of it, knowing that the molar mass of H2O is 18.02g/mol:

(where n is the number of moles, m is the mass of the sample and MM corresponds to the molar mass of the compound)

Therefore, 12.28 moles of H2O need to be produced in the reaction.

Next, let's determine the number of moles of O2 necessary to produce 12.28 moles of H2O. According to the balanced chemical equation, 6 moles of O2 are necessary to produce 6 moles of H2O:

6 mol H2O ------------------- 6 mol O2

12.28 mol H2O ------------- x

Solving for x, we have that 12.28 moles of O2 would be necessary to produce 12.28 moles of H2O.

At last, we need to convert the calculated number of moles of O2 to its correspondent mass, in grams. Knowing that the molar mass of O2 is 31.98g/mol, we can calculate the mass of O2 as:

Therefore, 392.71 g of O2 would be necessary to produce 221.3g of H2O.

Natasha is adding sugar to the water, a little at a time, and also she stopped adding sugar when no more sugar can be dissolved in the water. The two things she can do to involve the test are the same amount of water and the same water temperature.

When sugar is added to water, after a time it will stop dissolving since it reaches saturation point, so the amount, as well as temperature of the water, can be used to make the test. Sugar serves as a solute, which means that when it is added to water, the amount of vapor produced will decrease. Therefore, in order to achieve the boiling point after adding sugar (solute) to water, additional heat will be needed. As a result, the water's boiling point rises.

The amount of water stays the same because the sugar particles get trapped in the gaps between the water molecules. As the temperature of the water increases, it takes less time for the sugar to dissolve. The sugar can dissolve more readily into the gaps between the water molecules when the temperature is higher, hastening the formation of the solution.

Answer:

Density, \(d=0.82\ g/cm^3\)

Explanation:

It is given that,

Mass of an unknown liquid, m = 20.5 g

The volume of unknown liquid is 25 mL

We need to find the volume of the brass object. Mass per unit volume of an object is called its density.

We know that, 1 mL = 1 cm³

So, 25 mL = 25 cm³

\(d=\dfrac{m}{V}\)

Putting the values, we get :

\(d=\dfrac{20.5\ g}{25\ cm^3}\\\\d=0.82\ g/cm^3\)

So, the density of this substance is \(0.82\ g/cm^3\)

Density is a crucial physical quantity for a variety of materials, including liquids, gases, and solids. The temperature at which density is measured is usually specified because density is temperature-dependent and changes with temperature.

This implies that a small change in temperature will have a substantial effect on density.Let's have a look at the connection between temperature and density:T and ρ are the symbols used to represent temperature and density, respectively. It is common knowledge that substances expand when heated and contract when cooled. In the same vein, as temperature increases, the space between the molecules increases, resulting in a decrease in density. Conversely, if the temperature decreases, the molecules move closer together, and the density increases. When we consider the relationship between temperature and density, we can infer that density is directly proportional to temperature. As a result, when the temperature changes, so does the density, and this fluctuation must be specified. Therefore, specifying the temperature at which density is measured ensures accuracy and consistency in measurements. It also allows us to make appropriate comparisons between density values obtained from various sources. In conclusion, specifying temperature when measuring density ensures consistency and accuracy in results.

Answer: 1.44 × 10^-3 M.

Explanation: To calculate the [H3O+] of the solution, we need to consider the dissociation of HF (hydrofluoric acid) and the subsequent formation of H3O+ ions. Since HF is a weak acid, it partially dissociates in water.

The dissociation reaction of HF can be represented as follows:

HF + H2O ⇌ H3O+ + F-

The equilibrium constant for this reaction, Ka, is given as 7.2 × 10^-4.

Given:

[Molar concentration of HF] = 0.20 M

[Molar concentration of NaF] = 0.10 M

Assuming that the dissociation of HF is limited by the available F- ions from NaF, we can use the concept of the common ion effect to calculate the [H3O+] in the solution.

Since NaF is a salt that dissociates completely into Na+ and F- ions, the [F-] in the solution is equal to the concentration of NaF, which is 0.10 M.

Let's denote the concentration of [H3O+] as x M.

Using the equilibrium expression for the dissociation of HF:

Ka = [H3O+][F-] / [HF]

Substituting the known values:

7.2 × 10^-4 = x * 0.10 / 0.20

Simplifying the equation:

x = (7.2 × 10^-4) * (0.20 / 0.10)

x = 1.44 × 10^-3

Therefore, the [H3O+] of the solution is approximately 1.44 × 10^-3 M.

Approximately 402.27 grams of sodium azide (NaN₃) must decompose to fill a 55.0-gallon airbag.

The ideal gas law is a fundamental equation that describes the behavior of ideal gases under a wide range of conditions. It relates the pressure (P), volume (V), temperature (T), and number of moles of gas (n) of an ideal gas through the equation:

PV = nRT

where R is the gas constant, which has a value of 8.314 J/(mol·K) or 0.0821 L·atm/(mol·K) in SI units.

We know that the volume of the airbag is 55.0 gallons, so we need to convert this to liters using a conversion factor.

1 gallon = 3.78541 liters

Therefore, the volume of the airbag in liters is:

55.0 gallons x 3.78541 liters/gallon = 208.20 liters

Next, we need to calculate the number of moles of N₂ gas that would be produced from the decomposition of NaN₃ required to fill the airbag.

From the balanced equation:

2 NaN₃ (s) -> 2 Na (s) + 3 N₂ (g)

We can observe that two moles of NaN₃ result in three moles of N₂. Therefore, the number of moles of N2 produced is:

moles of N2 = (2/3) x moles of NaN₃

To fill the airbag, we need enough N₂ gas to occupy a volume of 208.20 liters. One mole of any gas has a volume of 22.4 litres at standard temperature and pressure (STP).

Therefore, the number of moles of N₂ required is:

moles of N₂ = (208.20/22.4) = 9.29 moles

Now we can use the balanced equation to calculate the number of moles of NaN₃ required:

2 NaN₃ (s) -> 2 Na (s) + 3 N2 (g)

For every 3 moles of N₂ produced, we need 2 moles of NaN3. Therefore, the number of moles of NaN₃ required is:

moles of NaN₃ = (2/3) x moles of N₂ = (2/3) x 9.29 = 6.19 moles

Finally, we can use the molar mass of NaN₃ to calculate the mass required:

mass of NaN₃ = moles of NaN₃ x molar mass of NaN₃

The molar mass of NaN₃ is:

Molar mass of NaN₃ = (1 x 22.99) + (3 x 14.01) = 65.01 g/mol

Therefore, the mass of NaN₃ required to fill the airbag is:

mass of NaN₃ = 6.19 moles x 65.01 g/mol = 402.27 grams

a. Under equilibrium conditions, the ratio of Pyruvate to PEP is \(3.78 * 10^6.\)

b. Under standard conditions for equilibrium, the ratio of ATP to ADP is 441.

c. This equation shows that PEP can drive the synthesis of ATP from ADP and Pi. REACTION 1 is in the forward direction, while REACTION 2 is in the reverse direction.

d. The overall net coupled reaction is exergonic or spontaneous because the ΔG' is negative (-92.4 kJ/mol). This means that the reaction releases energy and can proceed spontaneously without the addition of energy.

e. At equilibrium, the concentrations of PEP, ADP, Pi, H+, Pyruvate, and ATP will be equal.

a. The equilibrium constant (Keq) for REACTION 1 can be calculated using the equation:

ΔG° = -RT ln(Keq)

where R is the gas constant (8.314 J mol^-1 K^-1), T is the temperature in Kelvin (assumed to be 298 K), and ΔG° is the standard free energy change. Rearranging the equation to solve for Keq gives:

Keq = e^(-ΔG°/RT)

Substituting the given values, we get:

Keq =\(e^{(-(-61.9 kJ mol^{-1})/(8.314 J mol^{-1} K^{-1} * 298 K))}\) = \(2.10 * 10^8\)

The equilibrium constant expression for the hydrolysis of PEP can be written as:

Keq = [Pyruvate][Pi][\(H^+\)] / [PEP][\(H_2O\)]

At equilibrium, the ratio of products to reactants is equal to Keq. Therefore, the ratio of Pyruvate to PEP is:

[Pyruvate] / [PEP] = Keq / ([Pi][\(H^+\)]/[\(H_2O\)])

Substituting the given values, we get:

[Pyruvate] / [PEP] = \((2.10 * 10^8) / ((1 M)(10^{-7} M) / (55.5 M))\)

[Pyruvate] / [PEP] = \(3.78 * 10^6\)

b. The equilibrium constant (Keq) for REACTION 2 can be calculated in the same way as in part (a):

Keq = e^(-ΔG°/RT) = \(e^{(-(-30.5 kJ mol^{-1})/(8.314 J mol^{-1} K^{-1} * 298 K))} = 1.26 * 10^5\)

The equilibrium constant expression for the hydrolysis of ATP can be written as:

Keq = [ADP][Pi][\(H^+\)] / [ATP][\(H_2O\)]

At equilibrium, the ratio of products to reactants is equal to Keq. Therefore, the ratio of ATP to ADP is:

[ATP] / [ADP] = [\(H_2O\)] / ([Pi][\(H^+\)]/([ATP]Keq))

Substituting the given values, we get:

[ATP] / [ADP] = \((55.5 M) / ((1 M)(10^{-7} M)/(1 M)(1.26 * 10^5))\)

[ATP] / [ADP] = 441

c. The net coupled chemical equation for the synthesis of ATP from ADP and inorganic phosphate using the hydrolysis of PEP into Pyruvate can be written as:

PEP + ADP + Pi --> Pyruvate + ATP

This equation shows that PEP can drive the synthesis of ATP from ADP and Pi. REACTION 1 is in the forward direction, while REACTION 2 is in the reverse direction.

d. To calculate the ΔG' for the overall net coupled reaction, we need to sum up the ΔG' of the individual reactions.

ΔG'net = ΔG'1 + ΔG'2

ΔG'1 = -61.9 kJ/mol

ΔG'2 = -30.5 kJ/mol

ΔG'net = -61.9 kJ/mol + (-30.5 kJ/mol)

ΔG'net = -92.4 kJ/mol

e. The overall net coupled reaction can be written as follows:

PEP + ADP + Pi + \(H^+\) → Pyruvate + ATP

The ratio of products and reactants for the overall net coupled reaction can be calculated using the equilibrium constant (Keq). The equilibrium constant is defined as the ratio of the concentrations of products to the concentrations of reactants at equilibrium.

Keq = [Pyruvate][ATP]/[PEP][ADP][Pi][\(H^+\)]

At equilibrium, Keq = 10^(ΔG'net/(-RT))

where R is the gas constant (8.314 J/molK), T is the temperature (in Kelvin), and ΔG'net is the standard free energy change of the reaction.

Assuming standard conditions of 25°C (298 K), we get:

Keq = \(10^{(-92400/(8.314*298))\)

Keq = \(2.1 * 10^{27\)

The ratio of products to reactants is given by the coefficients in the balanced equation:

In such a way, since we are asked to compute the specific heat, we solve for it as shown below:

\(Cp=\frac{Q}{m\Delta T}=\frac{1870J}{75.01g*45.2\°C} \\ \\Cp=0.552\frac{J}{g\°C}\)

Best regards.

The specific heat of the metal exhibiting 45.2 \(\rm ^\circ C\) temperature change has been 0.55 J/g.\(\rm ^\circ C\).

The specific heat can be defined as the amount of heat required to raise the temperature of 1 gram of a substance by 1 degree Celsius.

Q = mc\(\Delta\)T

where, Q = heat required = 1870 J

m = mass = 75.01 g

c = specific heat capacity

\(\Delta\)T = change in temperature = 45.2 \(\rm ^\circ C\)

1870 J = 75.01 g \(\times\) c \(\times\) 45.2 \(\rm ^\circ C\)

c = \(\rm \dfrac{1870}{75.01\;\times\;45.2}\)

The order with respect to NO₃ is 1. The overall order of the reaction is 2. It is classified as a bimolecular reaction.

The elementary reaction equation is given as: NO₃ (g) + CO (g) → NO₂ (g) + CO₂ (g). To determine the order with respect to NO₃, we need to know the reaction rate law. Since it is an elementary reaction, the rate law can be directly written from the stoichiometry. The rate law for this reaction is: Rate = k[NO₃][CO], where k is the rate constant.

The order with respect to NO₃ is 1, as its concentration is raised to the power of 1 in the rate law. To find the overall order of the reaction, we sum the exponents of the concentration terms in the rate law: overall order = 1 (from NO₃) + 1 (from CO) = 2. Therefore, the overall order of the reaction is 2.

Since the reaction involves two reacting species (NO₃ and CO) colliding to form products, it is classified as a bimolecular reaction. Bimolecular reactions involve two reacting molecules coming together to form the products, in contrast to unimolecular reactions (involving a single reactant molecule) or termolecular reactions (involving three reactant molecules).
