A rigid tank contains 1.40 moles of an ideal gas. Determine the number of moles of gas that must be withdrawn from the tank to lower the pressure of the gas from 24.5 atm to 5.30 atm. Assume the volume of the tank and the temperature of the gas remain constant during this operation.

Answers

Answer 1

Answer:

Answer : The final number of moles of gas that withdrawn from the tank to lower the pressure of the gas must be, 0.301 mol.

Explanation :

As we know that:

$PV=nRT$

At constant volume and temperature of gas, the pressure will be directly proportional to the number of moles of gas.

The relation between pressure and number of moles of gas will be:

$(P_1)/(P_2)=(n_1)/(n_2)$

where,

$P_1$ = initial pressure of gas = 24.5 atm

$P_2$ = final pressure of gas = 5.30 atm

$n_1$ = initial number of moles of gas = 1.40 moles

$n_2$ = final number of moles of gas = ?

Now put all the given values in the above expression, we get:

$(24.5atm)/(5.30atm)=(1.40mol)/(n_2)$

$n_2=0.301mol$

Therefore, the final number of moles of gas that withdrawn from the tank to lower the pressure of the gas must be, 0.301 mol.

This problem has been solved!See the answerNaCl is an ionic solid. The Na+ and Cl− ions in NaCl are bonded through an electrostatic force of attraction commonly known as the ionic bond. Water is a polar solvent. The oxygen atom, being more electronegative, attracts the electron cloud toward itself. As the electron cloud is pulled by the oxygen atom, it carries a partial negative charge, and the hydrogen atoms carry a partial positive charge. This partial separation of charges in the water molecule makes it polar. Predict which intermolecular forces contribute the most to the dissolution of NaCl in water. Check all that apply.a.

C2H5OH is able to dissociate in water to conduct an electric current. This compound could be classified as

Answers

The fact that when in solution C₂H₅OH conducts electricity means that it is an electrolyte so you can automatically cross out A and C (the definition of an electrolyte is a substance that will conduct electricity when in a solution). I think the correct answer is B due to the -OH group (the - indicates a covalent bond) which allows the molecule to give up a proton (H⁺).
I hope this helps. Let me know if anything is unclear.

A _____ change occurs when a substance changes phase.
physical
chemical
nuclear

Answers

A physical change occurs when a substance changes phase.

For example, boiling pure water (H₂O) is physical change of substance (from liquid to gaseous state). In physical change, the bonds between oxygen and hydrogen can not be separated.

Sublimation of iodine (from solid to gas state) is also physical change.

Physical property can be observed and measured without any changes in molecular composition. The same substance is present before and after the change.

Final answer:

A physical change occurs when a substance changes phase. In this process, a substance may change from one state of matter to another but its foundational substance remains the same.

Explanation:

A physical change takes place when a substance alters its phase. This means that it shifts from one state of matter (solid, liquid, gas) to another. It's crucial to remember that although the physical characteristics of the substance may change, its substance does not. Let's take an example of water, it can exist as solid (ice), liquid (water), and gas (steam) but in all these states it remains H2O. Therefore, when a substance changes phase, it undergoes a physical change, not a chemical or a nuclear change.

Name four non-metal that could take the electron that the lithium loses when forming bonds

Answers

The elements that accept the electron of Lithium are Fluorine, Chlorine, Bromine, and Iodine.

Metals and nonmetals are the elements in the periodic table that gains and lose electrons to form chemical bonds.

The metals are a compound that loses electrons and nonmetals gains electrons to form a chemical bond.

Elements bonding with Lithium

Lithium has been a group 1 element with 1 valence electron. It has been bonding with the nonmetals that accept the electrons and form the bond. The elements complete their octet and become stable.

The nonmetals that require an electron to complete their octet are halogens. Thus, the elements that accept the electron of Lithium are Fluorine, Chlorine, Bromine, and Iodine.

Electrons are passed from carriers with lower reduction potential to those with higher reduction potential.B. The first electron carrier is also a proton pump.C. All electron carriers are mobile and hydrophobic.D. The electron carriers can transport a maximum of 2 electrons.

Answers

Answer:

C. All electron carriers are mobile and hydrophobic

Explanation:

Hello,

In this case, it is widely known that the electron carriers move inside the inner mitochondrial membrane and consequently move electrons from one to another. In such a way, they are mobile, therefore they are largely hydrophobic as long as they are inside the membrane.

For instance, the cytochrome c is a water-soluble protein in a large range, therefore, the answer is: C. All electron carriers are mobile and hydrophobic.

Best regards.
