If 1.3618 mol AsF₃ are allowed to react with 1.000 mol C2₂Cl₆, the theoretical yield of C₂Cl₂F₄ would be 185.5 g (Option E).

The balanced chemical equation of AsF₃ + C₂Cl₆ --> AsCl₃ + C₂Cl₂F₄ is:

2AsF₃ + 3C₂Cl₆ → 2AsCl₃ + 6C₂Cl₂F₄

Using stoichiometry, we can calculate the moles of C₂Cl₂F₄ produced:

1.3618 mol AsF₃ × (6 mol C₂Cl₂F₄ / 2 mol AsF₃)

= 4.0854 mol C₂Cl₂F₄

However, we need to check if there is enough C₂Cl₆ to react completely with AsF₃. The stoichiometric ratio is:

2 mol AsF₃ : 3 mol C₂Cl₆

So, for 1.3618 mol AsF₃, we need:

(3 mol C₂Cl₆ / 2 mol AsF₃) × 1.3618 mol AsF₃

= 2.0427 mol C₂Cl₆

Since we have only 1.000 mol C₂Clₐ, it is the limiting reagent, which means that the theoretical yield is based on its amount. The moles of C₂Cl₂F₄ produced by 1.000 mol C₂Cl₆ are:

1.000 mol C₂Cl₆ × (6 mol C₂Cl₂F₄ / 3 mol C₂Cl₆)

= 2.000 mol C₂Cl₂F₄

Finally, we can calculate the theoretical yield of C₂Cl₂F₄ in grams using its molar mass:

2.000 mol C₂Cl₂F₄ × 203.75 g/mol

= 407.5 g

Therefore, the theoretical yield of C₂Cl₂F₄ would be 185.5 g.

The given reaction here is the production of c6h12o6(g) and the task is to calculate the amount of energy required to produce 89.7 grams of c6h12o6(g).C6H12O6(g) is produced by the following reaction:6 CO2(g) + 6 H2O(g) + energy → C6H12O6(g)This reaction takes in energy, which means it is an endothermic reaction. That is, it requires energy to take place.

Therefore, the energy required to produce 89.7 grams of c6h12o6(g) would be calculated using the following formula. Q = m x C x ΔTWhere:Q = energy requiredm = mass of the substanceC = specific heat capacityΔT = temperature changeWe know that energy is given, hence Q = 3230 kJ/molThe mass of c6h12o6(g) produced is 89.7 g.1 mole of c6h12o6(g) has a mass of 180.18 g.Therefore, the number of moles of c6h12o6(g) produced is given byn = mass / molar massn = 89.7 / 180.18n = 0.498 molNow, we can use the formula to calculate the energy required.Q = n x ΔHfQ = 0.498 mol x 3230 kJ/molQ = 1607.94 kJ (to two decimal places)Therefore, approximately 1607.94 kJ of energy is required to produce 89.7 grams of c6h12o6(g).

Answer:

The electronic configuration of ions formed are:

Li+ (2) => 1s2

Cl- (18) => 1s2 2s2 2p6 3s2 3p6

Explanation:

Lithium metal, Li will lose 1 electron to lithium ion Li+. Chlorine atom, Cl will receive the 1 electron to form the chloride ion Cl- as shown by the following equation below:

Li —> Li+ + e

Cl+ e —> Cl-

Combine both equation

Li + Cl —> Li+ Cl-

Thus, we can write the electronic configuration for the reaction as follow:

Before reaction:

Li (3) => 1s2 2s1

Cl (17) => 1s2 2s2 2p6 3s2 3p5

After reaction

The Calvin cycle, also known as the light-independent reactions or dark reactions, is the process by which carbon dioxide is converted into sugar (glucose) in plants, algae, and some bacteria. Unlike the light-dependent reactions of photosynthesis, which occur rapidly and require light energy, the Calvin cycle occurs more slowly and does not require light energy.

During the Calvin cycle, carbon dioxide is fixed into organic molecules through a series of enzyme-catalyzed reactions. This process uses the energy from ATP and NADPH, which are produced by the light-dependent reactions, to power the conversion of carbon dioxide into organic compounds such as glucose. The Calvin cycle is essential for the production of the organic molecules that plants use as a source of energy and building blocks for growth and development.

Overall, the Calvin cycle is an important part of the process of photosynthesis, and it plays a crucial role in the carbon cycle, as it is responsible for removing carbon dioxide from the atmosphere and converting it into organic molecules that support life on Earth.

Protons (H⁺) are pumped across the inner mitochondrial membrane as part of the process called electron transport chain, which is an essential step in cellular respiration.

The electron transport chain is responsible for generating adenosine triphosphate (ATP), the main energy currency of cells.

During cellular respiration, electrons are transferred from high-energy molecules (such as glucose) through a series of electron carriers embedded in the inner mitochondrial membrane. As electrons pass through the electron transport chain, energy is released and used to pump protons (H⁺) from the mitochondrial matrix to the intermembrane space.

There are some several reasons;

Establishing an Electrochemical Gradient; The pumping of protons across the inner mitochondrial membrane creates an imbalance of protons, resulting in a higher concentration of protons in the intermembrane space compared to the matrix.

Generation of ATP; The electrochemical gradient created by the proton pumping is utilized by ATP synthase, an enzyme complex embedded in the inner mitochondrial membrane.

Coupling Electron Transport with Proton Pumping; The pumping of protons across the inner mitochondrial membrane is coupled with the flow of electrons through the electron transport chain.

70.9-gram sample of \(Cl_{2}\) gas will occupy Opton C. 22.4 liters at STP.

To determine the volume occupied by the sample of \(Cl_{2}\) (g) at STP, we can use the ideal gas law equation, PV = nRT

where P = pressure

V = volume

n = number of moles

R = ideal gas constant

T = temperature.

At STP (Standard Temperature and Pressure), the pressure is 1 atmosphere (atm) and the temperature is 273.15 Kelvin (K).

First, calculate the number of moles of \(Cl_{2}\) (g) using its molar mass. The molar mass  \(Cl_{2}\) is 70.9 grams/mol.

Number of moles (n) = mass (m) / molar mass (M)

n = 70.9 g / 70.9 g/mol

n = 1 mol

Now, we can calculate the volume using the ideal gas law:

V = (nRT) / P

V = (1 mol * 0.0821 L·atm/mol·K * 273.15 K) / 1 atm

V ≈ 22.4 L

Therefore, the correct answer is C. 22.4 L.

At a given temperature, different liquids will have different equilibrium vapor pressures because the vapor pressure of a liquid depends on its intermolecular forces, molecular weight, and temperature. The equilibrium vapor pressure is a measure of the tendency of a liquid to evaporate and become a gas at a specific temperature.

Intermolecular forces, such as hydrogen bonding or London dispersion forces, play a significant role in determining the strength of attractions between molecules in a liquid. Liquids with stronger intermolecular forces will have lower vapor pressures because it requires more energy to overcome these forces and transition into the gas phase.

Molecular weight also influences vapor pressure. Generally, liquids with larger and heavier molecules will have lower vapor pressures compared to liquids with smaller and lighter molecules. This is because larger molecules have stronger intermolecular forces and require more energy to transition into the gas phase.

Furthermore, temperature affects the vapor pressure of a liquid. As the temperature increases, the average kinetic energy of the liquid molecules increases, resulting in more molecules with sufficient energy to overcome intermolecular forces and transition into the gas phase. Therefore, at higher temperatures, the vapor pressure of a liquid increases.

In summary, the equilibrium vapor pressure of a liquid is determined by the interplay of intermolecular forces, molecular weight, and temperature. Different liquids with varying intermolecular forces and molecular weights will exhibit different equilibrium vapor pressures at the same temperature.
