is 1250g of carbon is reacted with excess water, and 710g of methane (ch4) was recovered, what was the percent yield of the reaction

If methane is compressed in a steady-state adiabatic compressor (87% efficient) to 0.4 mpa, then the required work per mole of methane is 4.04 kJ/mol.

To determine the required work per mole of methane, we can use the following formula:

[tex]W = \frac{(P_2V_2 - P_1V_1)}{n} * \eta[/tex]

Where:

W is the work done per mole of methane in kJ

P₁ is the initial pressure of methane

V₁ is the initial volume of methane

P₂ is the final pressure of methane

V₂ is the final volume of methane

n is the number of moles of methane

η is the efficiency of the compressor

Assuming that the compression process is reversible and adiabatic, we can use the following relationships:

[tex]\frac{P_2}{P_1} = (\frac{V_1}{V_2})^{\gamma}[/tex]

[tex]\frac{T_2}{T_1} = (\frac{V_1}{V_2})^{(\gamma-1)}[/tex]

where:

[tex]\gamma = \frac{C_p}{C_v}[/tex]  is the ratio of specific heats of methane

[tex]C_p[/tex]  is the specific heat at constant pressure

[tex]C_v[/tex]  is the specific heat at constant volume

Since the process is adiabatic, there is no heat transfer (Q = 0) and therefore the compression is reversible, so we can use the above relationships.

Let's assume that we have one mole of methane, and use the ideal gas law to find the initial volume:

[tex]P_1V_1 = nRT_1[/tex]

Where:

R is the gas constant for methane

T₁ is the initial temperature

Assuming standard temperature and pressure (STP) conditions (T₁ = 273.15 K, P₁ = 1 atm), we have:

[tex]V_1 = \frac{nRT_1}{P_1} = \frac{(1)*(8.314 )*(273.15)}{(1 * 101.325)} = 22.414[/tex] L/mol

Next, we can use the relationships for adiabatic compression to find the final volume and temperature:

[tex]\frac{P_2}{P_1} = (\frac{V_1}{V_2})^{\gamma}[/tex]

⇒ [tex]\frac{0.4}{101.325} = (\frac{22.414}{V_2})^{1.31}[/tex]

[tex]V_2 = 6.903[/tex] L/mol

[tex]\frac{T_2}{T_1} = (\frac{V_1}{V_2})^{\gamma-1}[/tex]

[tex]T_2 = T_1 * (\frac{V_1}{V_2})^{\gamma -1}[/tex]

[tex]T_2 = 273.15* (\frac{22.414}{6.903})^{(1.31-1)}[/tex]

[tex]T_2 = 550.1 K[/tex]

Now we can substitute the values into the formula for work:

[tex]W = \frac{(P_2V_2 - P_1V_1)}{n} * \eta[/tex]

[tex]W = \frac{[(0.4*6.903) - (1*22.414)]}{1} * 0.87[/tex]

[tex]W = -4.04[/tex] kJ/mol

the negative sign indicates that work is done on the system (i.e. the compressor does work on the methane). Therefore, the required work per mole of methane is -4.04 kJ/mol

A student asked about the amount of nickel plated out of a Ni(NO3)2 solution when a current of 5.41 A is passed through it for 1.90 hours.

To determine this, we can use Faraday's laws of electrolysis.

First, we need to find the charge passed through the solution. Charge (Q) can be calculated using the formula Q = I × t, where I is the current and t is the time in seconds. Since 1 hour is equal to 3600 seconds, 1.90 hours is equal to 1.90 × 3600 = 6840 seconds.

Now we can calculate the charge: Q = 5.41 A × 6840 s = 36996 Coulombs.

Next, we need to determine the amount of nickel deposited. The relationship between charge and moles of substance can be described using Faraday's constant (F), which is approximately 96485 Coulombs/mol of electrons. The balanced half-reaction for the reduction of Ni(II) ions is:

Ni(II) + 2e- → Ni(s)

Thus, 2 moles of electrons are needed to deposit 1 mole of nickel. Now we can calculate the moles of nickel

Moles of Ni = (Q × (1 mole Ni / (2 moles e-))) / F = (36996 C × (1 mole Ni / (2 moles e-))) / 96485 C/mol = 0.1918 moles Ni.

Finally, we need to convert moles of nickel to grams. The molar mass of nickel is 58.69 g/mol. So, the mass of nickel deposited is

Mass of Ni = moles of Ni × molar mass = 0.1918 moles × 58.69 g/mol = 11.26 grams.

Therefore, 11.26 grams of nickel is plated out of the Ni(NO3)2 solution when a 5.41 A current is passed through it for 1.90 hours.

These factors do not increase the solubility of a gas in a liquid, decreased volume of the gas, with pressure and temperature held constant and decreased partial pressure of the gas. Option a and d are correct choices.

Increased partial pressure of the gas: According to Henry's Law, the solubility of a gas in a liquid is directly proportional to the partial pressure of the gas above the liquid. Therefore, increasing the partial pressure of the gas will increase its solubility in the liquid.

Decreased temperature: As temperature decreases, the solubility of gases in liquids increases. This is because gases are more soluble in colder liquids than in warmer liquids. Therefore, decreasing the temperature will increase the solubility of the gas in the liquid.

Decreased partial pressure of the gas: As mentioned before, the solubility of a gas in a liquid is directly proportional to the partial pressure of the gas above the liquid. Therefore, decreasing the partial pressure of the gas will decrease its solubility in the liquid.

Decreased volume of the gas, with pressure and temperature held constant: According to Boyle's Law, the volume of a gas is inversely proportional to its pressure, when temperature is held constant. Therefore, decreasing the volume of the gas while keeping pressure and temperature constant will increase the pressure of the gas. This increase in pressure will tend to decrease the solubility of the gas in the liquid. Hence option a and d are correct.

Without additional information about the chemical reaction involved, we cannot determine the equilibrium pressures of cis-2-butene and trans-2-butene. But with the given information it could be 0.0485atm.

It is mandatory to note that the given pressures only represent the initial partial pressures of each gas in the mixture. So, in order to determine the equilibrium pressures, we would need to know the conditions of the reaction, such as the temperature, the presence of a catalyst, and the products formed.

Substitute the given values and solve for the unknowns: 3.40 = P(trans-2-butene) / 0.250 P(trans-2-butene) = 0.850 atm P(cis-2-butene) = (0.165 atm) / 3.40 P(cis-2-butene) = 0.0485 atm

Therefore, the equilibrium pressure of trans-2-butene is 0.850 atm and the equilibrium pressure of cis-2-butene is 0.0485 atm.

If we assume that the cis-2-butene and trans-2-butene are in a mixture at equilibrium, we would need to know the equilibrium constant for the reaction in order to determine the equilibrium concentrations (or partial pressures) of each gas.

Neither of the statements is correct concerning the acid ionization constant, Ka, of iodous acid, HIO₂.

When more HIO₂ is dissolved into water, the pH of the solution will change. This is because HIO₂ is a weak acid and will undergo dissociation in water to produce H⁺ ions and IO₂⁻ ions. The concentration of H⁺ ions will affect the pH of the solution.

Similarly, the value of Ka will also change if more HIO₂ is dissolved into water. Ka is the equilibrium constant for the dissociation of HIO₂ in water. If more HIO₂ is dissolved into water, the equilibrium will shift to the right, resulting in an increase in the concentration of H⁺ ions and IO₂⁻ ions.

This will result in an increase in the value of Ka, as Ka is directly proportional to the concentration of H⁺ ions produced by the dissociation of the weak acid.

Among all the substances used, water possesses the strongest intermolecular forces (hydrogen bonds).

Although hydrogen bonds exist in glycerine and methylated spirits as well, they are a little weaker than in water. Due to its nonpolar nature and minimal London dispersion forces, CH4 (methane) would exhibit the smallest intermolecular forces of attraction.

In particular, a subgroup of dipole-dipole interactions known as hydrogen bonding, which takes place when a hydrogen is in close proximity to (attached to) a very electronegative element, is the strongest intermolecular force (namely oxygen, nitrogen, or fluorine).

For a first-order reaction, the rate of the reaction is proportional to the concentration of the reactant:

Rate = k[A]

Where [A] is the concentration of the reactant and k is the rate constant. The integrated rate law for a first-order reaction is:

ln([A]t/[A]0) = -kt

Where [A]t is the concentration of the reactant at time t and [A]0 is the initial concentration.

To find the first and second half-lives, we need to use the fact that the reaction is 75% complete after 395 s. This means that [A]t/[A]0 = 0.25, and we can substitute this value into the integrated rate law:

ln(0.25) = -k(395)

Solving for k, we get:

k = ln(0.25) / (-395) ≈ 0.00226 s^-1

The first half-life is the time it takes for the concentration of the reactant to decrease to half of its initial value. We can use the integrated rate law to solve for the first half-life:

ln(0.5) = -k(t1/2)

Solving for t1/2, we get:

t1/2 = ln(2) / k ≈ 307 s

The second half-life is the time it takes for the concentration of the reactant to decrease to one-fourth of its initial value. We can use the same equation and substitute [A]t/[A]0 = 0.25 again:

ln(0.25) = -k(t2/2)

Solving for t2/2, we get:

t2/2 = ln(4) / k ≈ 1229 s

Therefore, the first half-life for this reaction is approximately 307 s, and the second half-life is approximately 1229 s.

Therefore, the specific heat of the material is approximately 68.57 J/(kg·°C).

C = Q /(m  T) is the equation for the specific heat capacity of a material with mass m. where Q is the additional energy and T is the temperature difference.

We can use the formula for heat:

Q = mcΔT

In this instance, we are aware that a 35 g sample, heated from 293 K to 313 K, received 48 J. We can enter these numbers into the algorithm to find c:

48 J = (35 g) x c x (313 K - 293 K)

First, we must convert the temperature differential from Kelvin to Celsius as well as the mass from grammes to kilogrammes:

Answer:

The molar mass of the gas is closest to that of molecular bromine (Br2), which has a molar mass of 159.8 g/mol. Therefore, the diatomic gas is likely to be bromine.

Explanation:

To solve this problem, we can use the ideal gas law, which relates the pressure, volume, temperature, and number of moles of a gas. The ideal gas law is given by:

PV = nRT

where P is the pressure, V is the volume, n is the number of moles, R is the ideal gas constant, and T is the temperature in Kelvin.

First, we need to convert the temperature and volume to Kelvin and liters, respectively:

T = 23.0°C + 273.15 = 296.15 K

V = 125.0 mL / 1000 mL/L = 0.125 L

Next, we can rearrange the ideal gas law to solve for the number of moles:

n = PV/RT

where R is the ideal gas constant, which has a value of 0.08206 L·atm/(mol·K).

We can substitute the given values into this equation:

n = (750. torr)(0.125 L) / (0.08206 L·atm/(mol·K))(296.15 K) = 0.00408 mol

Now we can calculate the molar mass of the gas by dividing its mass by its number of moles:

molar mass = mass / moles

molar mass = 0.360 g / 0.00408 mol = 88.2 g/mol

The molar mass of the gas is 88.2 g/mol.

To determine the identity of the gas, we can compare its molar mass to the molar masses of common diatomic gases. The molar mass of the gas is closest to that of molecular bromine (Br2), which has a molar mass of 159.8 g/mol. Therefore, the diatomic gas is likely to be bromine.

The molar mass of the diatomic gas is approximately 67.9 g/mol. Considering common diatomic gases, it is likely to be Cl₂ (chlorine gas), which has a molar mass of 70.9 g/mol.

To determine the molar mass of the diatomic gas, we can use the Ideal Gas Law equation:

PV = nRT

First, we need to convert the given information to appropriate units.

1. Volume (V): 125.0 mL = 0.125 L (1 L = 1000 mL)

2. Temperature (T): 23.0 °C = 296.15 K (K = °C + 273.15)

3. Pressure (P): 750 torr = 0.9869 atm (1 atm = 760 torr)

Now we can rearrange the Ideal Gas Law equation to solve for n (moles of gas):

n = PV / RT

Plugging in the given values:

n = (0.9869 atm)(0.125 L) / (0.0821 L atm/mol K)(296.15 K)
n ≈ 0.0053 moles

Now, we can find the molar mass (MM) of the diatomic gas using the given mass and the calculated moles:

MM = mass/moles

MM = 0.360 g / 0.0053 moles
MM ≈ 67.9 g/mol

Acetic acid donates only the hydrogen atom bonded to the oxygen atom, because the oxygen is more electronegative and better accommodates a negative charge after the bond is broken.

In acetic acid, there are 4 hydrogen atom, but it acts as a monoprotic acid. Three of the hydrogen atoms is bonded to the carbon atom and one hydrogen atom is bonded to the oxygen atom. The electronegativity difference between carbon and hydrogen is much less than that between oxygen and hydrogen.

As a highly electronegative atom, oxygen tends to pull the electrons in the O-H bond to itself. Due to this, the hydrogen will be loosely bound compared to that bonded with carbon. Also the oxygen is capable of accommodating the  negative charge after the bond is broken.

So acetic acid is a monoprotic acid and only one hydrogen gets donated.

The direction in which the reaction will initially proceed depends on the value of the equilibrium constant (K). If you know K, compare it with the calculated reaction quotient (Q = 20) to determine the direction of the reaction.

To determine the direction in which the reaction will proceed, we need to compare the initial reaction quotient (Q) with the equilibrium constant (K).

Step 1: Calculate the initial concentrations of the reactants and products
Since all substances are mixed in a one-liter container, their concentrations are as follows:
[A] = 0.0010 mol/L
[B] = 5.0 mol/L
[C] = 0.10 mol/L

Step 2: Determine the reaction quotient (Q) using the given concentrations
The reaction quotient is calculated using the formula Q = [C]/([A]*[B]). Plug in the concentrations from step 1:
Q = (0.10) / (0.0010 * 5.0) = 0.10 / 0.005 = 20

Step 3: Compare Q with the equilibrium constant (K)
Without the specific equilibrium constant (K) for the reaction, we cannot provide a definitive answer. However, based on the value of Q, we can infer the following:

- If Q < K, the reaction will proceed forward (to the right) to reach equilibrium.
- If Q > K, the reaction will proceed backward (to the left) to reach equilibrium.
- If Q = K, the reaction is already at equilibrium.

Since the volume of HCl used is 50.00 ml (0.05000 L) at the equivalence point, we can calculate the original concentration of the HCl as follows:

0.005 mol / 0.05000 L = 0.100 mol/L

Photosynthesis is the process by which plants, algae, and some bacteria convert light energy into chemical energy. During photosynthesis, light energy is absorbed by pigments called chlorophyll, which is located in the chloroplasts of plant cells. This energy is then used to power a series of chemical reactions that convert carbon dioxide and water into glucose (a type of sugar) and oxygen.

The overall equation for photosynthesis is:

6CO₂ + 6H₂O + light energy → C₆H₁₂O₆ + 6O₂

In this equation, carbon dioxide (CO₂) and water (H₂O) are combined in the presence of light energy to produce glucose (C₆H₁₂O₆ ) and oxygen (O₂). The glucose produced by photosynthesis is used by the plant as a source of energy, while the oxygen is released into the atmosphere as a byproduct. Photosynthesis plays a vital role in the Earth's carbon cycle and is responsible for producing the oxygen that is essential for life on Earth.

Out of the given options, maple syrup is likely to be the most adhesive due to its high sugar content.

Ability of a substance to stick to any surface is called as adhesion. It depends on various factors such as the chemical composition of the substance, the surface properties of the material, and the environmental conditions like temperature and humidity.

Out of the given options, maple syrup is likely to be the most adhesive due to its high sugar content. Sugars have a high affinity for water, which allows them to form strong hydrogen bonds with surfaces. This property makes maple syrup stickier and more adhesive than other substances.

Ketchup and barbeque sauce also contain sugar, but they typically have a lower sugar content than maple syrup, so they may not be as adhesive. Mustard contains less sugar and is more acidic than the other options, which can reduce its adhesion.

The gas inside the balloon exerts extra pressure on its walls as a result of the increased molecular mobility, which causes the balloon to expand.

Pressure: As the temperature of the gas inside the balloon increases, the pressure of the gas also increases.

This is because the gas molecules gain kinetic energy with the increase in temperature, resulting in more frequent and forceful collisions with the walls of the balloon. This leads to an increase in pressure inside the balloon, causing it to expand.

Volume: Due to the increase in pressure inside the balloon, the volume of the gas inside the balloon also increases. The balloon expands and stretches to accommodate the increased volume of the gas.

Temperature: The temperature of the gas inside the balloon also increases as it absorbs heat from the hot water.

However, the rate of increase in temperature may be slower compared to the water temperature due to the heat capacity of the balloon material and the heat transfer rate.

Therefore, This increased molecular motion causes the gas inside the balloon to exert more pressure on the walls of the balloon, resulting in the expansion of the balloon.

STP, or standard temperature and pressure, is a set of conditions used for comparing and measuring gases. STP is defined as a temperature of 0°C (273.15 K) and a pressure of 1 atmosphere (atm).

To determine the pressure of 0.6 moles of a gas sample collected at STP conditions, we can use the ideal gas law, which states that PV = nRT, where P is the pressure, V is the volume, n is the number of moles, R is the universal gas constant, and T is the temperature.

At STP conditions, the temperature T is 0°C or 273.15 K, and the number of moles n is given as 0.6. We also know that the volume V of the gas sample is equal to 22.4 L, which is the molar volume of any gas at STP.

Using these values, we can rearrange the ideal gas law equation to solve for the pressure P:

P = nRT/V

Substituting the known values, we get:

P = (0.6 mol)(0.0821 L·atm/mol·K)(273.15 K) / 22.4 L

P = 1.98 atm

Therefore, the pressure of 0.6 moles of a gas sample collected at STP conditions is 1.98 atm.

The dominant species in solution at the equivalence point of a weak base-strong acid titration is neutral salt. The correct answer is option 5.

A salt is a compound formed from the combination of an acid and a base. The acid and base neutralize each other, resulting in the formation of a neutral salt. The salt's pH will be determined by the strength of the acid and base that made it.A neutral salt is formed when the acid and base are strong or when they are of equal strength.

If the acid is strong and the base is weak, the salt will be acidic, and if the base is strong and the acid is weak, the salt will be basic. At the equivalence point of a weak base-strong acid titration, the dominant species in solution is a neutral salt.

At the endpoint, the pH of the solution will be less than 7 because the acid has been added to the solution. However, at the equivalence point, the acid and base have completely reacted to form a neutral salt, which is neither acidic nor basic. The correct answer is option 5.
