Answers

The gas will occupy 0.2624 L at 34.0 [tex]^oC[/tex] and 0.922 atm pressure.

Ideal gas problem

For an ideal gas:

PV = nRT

Where P is the pressure of the gas, V is the volume of the gas, R is the ideal gas constant, and T is the temperature in kelvin.

In this case:

P = 0.922 atm

V is what we are looking for

n = 0.00961 mol

R = 0.082 L atm.mol−1⋅K−1

T = 34 + 273 = 307 kelvin

Making V the subject of the formula:

V = nRT/P

  = 0.00961 x 0.082 x 307/0.922

Answers

C. nonpolar covalent is the nature of C-Cl bond in the compound CCl4 having (Electronegativity: C-2.5, C-3,0).

A covalent bond is a chemical bond formed by the sharing of electrons between two atoms. The bond between C and Cl in CCl4 is a covalent bond. The electronegativity difference between C and Cl is small (EN C = 2.5 and EN Cl = 3.0), indicating that the bond is nonpolar covalent. In a nonpolar covalent bond, the electrons are shared equally between the atoms, and there is no separation of charge. The atoms have the same pull on the electrons, meaning that the electrons are shared equally between the atoms. In this case, the bond between C and Cl is nonpolar covalent because the electronegativity of C and Cl are similar, and the electrons are shared equally. Therefore, the bond is not polarized and there is no separation of charge. To sum up, C-Cl bond in CCl4 is not ionic and not polar covalent, it is a nonpolar covalent bond.

Is NADH the final electron acceptor?

Answers

No, isn't. NADH (nicotinamide adenine dinucleotide) is not the final electron acceptor in cellular respiration.

NADH

In the final stage of cellular respiration, the electron transport chain uses a series of electron carriers to transfer electrons from NADH and FADH2 to the final electron acceptor, which is oxygen (O2). The energy from these electrons is used to pump protons across a membrane, creating a proton gradient that drives the production of ATP through ATP synthase.

If you want to obtain the final electron acceptor in cellular respiration, you would need to provide an alternative electron acceptor in the electron transport chain. The most common final electron acceptors used in cellular respiration are oxygen (O2) in aerobes and non-oxygen compounds such as nitrate (NO3-), sulfur (S), or carbon dioxide (CO2) in anaerobes.

Mole ratio of reactants in reactions

The normal balanced equation of reaction between sodium (Na) and chlorine molecule (Cl2) is as follows:

Thus 2 moles of Na is required to completely react with 1 mole of [tex]Cl_2[/tex] to produce 1 mole of NaCl.

In the reaction depicted reaction 4 moles of Na and 12 moles of [tex]Cl_2[/tex] were made available for the production of NaCl. However, the mole ratio for a complete reaction is 2 moles of Na to 1 mole of NaCl.

Answers

According to question the pressure of the gas is 4.45 atm.

What is pressure?

Pressure is a physical force exerted on a surface by an object or a liquid. It is measured in units of force per unit area, such as pounds per square inch (psi) or pascals (Pa). Pressure is created when a force is applied to an object, causing it to compress or expand.

The pressure of the gas can be calculated using 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 ideal gas constant, and T is the temperature.

To calculate the pressure, we first need to calculate the number of moles of CO₂ gas in the container. We can do this by using the molar mass of CO₂, which is 44.01 g/mol.
n = (78.1 g CO₂) / (44.01 g/mol) = 1.77 mol
Now that we have the number of moles, we can calculate the pressure using the ideal gas law.
P = (1.77 mol)(0.0821 L·atm/K·mol)(273 K) / (48.0 L)

How do you find partial pressure from mole fraction?

Answers

To find partial pressure from mole fraction, we have to multiply mole fraction with total pressure in the event.

How to find partial pressure with example?

Partial pressure is a result of multiplying of mole fraction and total pressure or in formula it is written as Pfraction = molefraction x Ptotal. To make it easief for you to understand, let's see the example below:

Let say we have a room with 24.2 g of He and 4.32 g of O2 at 2.611 atm pressure. In this case, before we calculate the partial pressure we have to calculate the mole fraction

24.2 g Neon x 1 mol Neon / 20.18 g Neon = 1.199 mol Neon

4.32 g Oxygen x 1 mol Oxygen / 31.998 g O2 = 0.135 mol Oxygen.

Total moles =  1.199 x 0.135 = 1.334 mol gas

Mole fraction Ne = 1.199 mol/1.334 mol = 0.899

Mole fraction O₂ = Oxygen: 0.135/1.334 = .101

Then find the partial pressure

PNe = mole fraction Ne x Ptot = 0.899 x 2.611 atm = 2.35 atm

PO2 = mole fraction O ₂ x Ptot = 0.101 x 2.611 atm = 0.264 atm

what mass of CO2 will be produced from the reaction of 37.5 g c2h6?

Answers

The mass of carbondioxide that will be produced from the reaction of 37.5g of C₂H₆ is 110 grams.

How to calculate moles using stoichiometry?

Stoichiometry is the study and calculation of quantitative (measurable) relationships of the reactants and products in chemical reactions (chemical equations).

According to this question, ethane reacts with oxygen to produce carbondioxide and water as follows:

2C₂H₆ + 7O₂ → 4CO₂ + 6H₂O

Based on the above reaction, 2 moles of ethane produces 4 moles of carbondioxide

37.5g of ethane = 1.25moles of ethane

moles of carbondioxide = (1.25 × 4) ÷ 2 = 2.5 moles

mass of carbondioxide = 2.5mol × 44g/mol = 110grams of carbondioxide.
