An ideal gas (which is is a hypothetical gas that conforms to the laws governing gas behavior) confined to a container with a massless piston at the top. (Figure 2) A massless wire is attached to the piston. When an external pressure of 2.00 atm is applied to the wire, the gas compresses from 6.40 to 3.20 L . When the external pressure is increased to 2.50 atm , the gas further compresses from 3.20 to 2.56 L .

In a separate experiment with the same initial conditions, a pressure of 2.50 atm was applied to the ideal gas, decreasing its volume from 6.40 to 2.56 L in one step.

If the final temperature was the same for both processes, what is the difference between q for the two-step process and q for the one-step process in joules?

Answers

Answer 1

Answer: -162,120J

Explanation:

Okay, so q stands for work, given by the formula q = -P∆V,

For the first round, we have 2atm (for P) and a volume change of 3.2 (6.4-3.2) for the first experiment.

Find the work: q = -2 • (3.2 - 6.4) = 6.4L/atm

For the second experiment, it is now 2.5atm, with the change in volume going from 3.2 to 2.56.

So, work is q = -2.5(2.5 - 3.20) = 1.6L/atm

Add the total work: 1.6 + 6.4 = 8L/atm

To find the Joules per L/atm, recall that a mol of gas in K is 8.31447J, while the gas constant where a liter of gas per mol in K is 0.08206L/atmK. Divide these two values, which leaves us with 101,325J

So, for the first round, multiply 8 x 101,325, which leaves us with 810,600J.

Second round: The pressure is 2.5atm, with the volume change from 6.40 to 2.56

Solve for work: q = -2.5(2.56-6.4) = 9.6L/atm

Multiply with the Joule unit found earlier: 9.6 x 101,325 = 972,720J.

To find the difference, subtract the value of the single-step process (second round) from the first round (multistep)

810600 - 972720 = -162,120J. Therefore, it takes more heat to do the single step than the multistep process.

How the structure of molecule affects physical properties?

Answers

The structure of a molecule affects its physical properties because the arrangement of the atoms in the molecule determines the type of forces that interact between molecules.

And that forces affect how the molecules move and interact with each other. This, in turn, affects the physical properties of the molecule, such as its melting point, boiling point, polarity, and solubility.

For example, when a molecule has a higher number of non-polar bonds due to symmetrical structures, it will be less polar overall and have fewer attractive forces acting between molecules, resulting in a higher boiling point and lower solubility.

On the other hand, a molecule with a higher number of polar bonds due to asymmetrical structures will be more polar overall, leading to stronger attractive forces acting between molecules, resulting in a lower boiling point and higher solubility.

Answers

The empirical formula for this compound containing 59.94 % carbon, 13.44 % hydrogen, and 26.62 % oxygen by mass is C3H8CO.

Given the % of carbon = 59.94%

The % of hydrogen = 13.44%

The % of oxygen = 26.62%

If a percentage is provided, we will assume that the entire mass is 100 grams. As a result, each element's mass is equal to the percentage indicated. Then

the mass of carbon (m1) = 59.94g

The mass of hydrogen (m2) = 13.44g

The mass of oxygen (m3) = 26.62g

We know the molar mass of C = 12 g/mole

The Molar mass of H = 1 g/mole

The Molar mass of O = 16 g/mole

The moles of carbon = 59.94/12 = 4.995

The moles of hydrogen = 13.44/1 = 13.44

The moles of oxygen = 26.62/16 = 1.664

Divide each mole value by the lowest computed mole number to get the mole ratio.

For C = 4.995/1.664 = 3 , For H = 13.44/1.664 = 8 and For O = 1.664/1.664 = 1. Then the empirical formula = C3H8CO

The word rock relates to the material's bulk volume, which includes the grain or crystals in addition to the enclosed vacuum space.

The two characteristics of the rock are:

Some minerals exhibit color features related to mineral composition and atom arrangement: for example, magnetite is black, chlorite is green, and pyrite is brassy yellow.

The capacity of a mineral to resist scratching is used to estimate its hardness, which is generally determined on fresh material. When a mineral is scraped with a knife, it softens. If a knife cannot scratch it, the two have equivalent hardness or even the mineral is harder.

Therefore, the two characteristics of the rock can be given as above.

In what part of this system are the two energy outputs found?

Answers

The part of the system that has two outputs of energy is the bulb.

What is the energy transformation?

We would have to recall that on the basis of the first law of thermodynamics, it can be said that energy can not be created nor destroyed but that energy would have to be converted from one form to the other.

In this case, we can see that as the boy is cycling, there is the conversion of the mechanical energy of the boy to the heat and the light energy of the bulb as shown. These are the outputs referred to above.

Which of the following best describes the side chain of arginine at a pH of 11?
nonpolar
uncharged but polar
charged and polar
aprotic
hydrophobic
Charged and polar is incorrect. My textbook says the pKa of the sidechain is 12.48. Can you please explain what the correct answer is?

Answers

At a pH of 11, the side chain of arginine would be positively charged (NH3+) and polar.

This is because the pKa of the guanidine group (NH2) in the side chain of arginine is 12.48, which means that at a pH greater than 12.48, the guanidine group will be protonated and carry a positive charge. Since the nitrogen atom in the guanidine group is also surrounded by hydrogen atoms, the side chain is polar.

Key points:

The side chain of arginine is a guanidine group (NH2).The pKa of the guanidine group is 12.48, which means that at a pH greater than 12.48, the guanidine group will be protonated (NH3+).When protonated, the guanidine group carries a positive charge.The nitrogen atom in the guanidine group is surrounded by hydrogen atoms, which makes the side chain polar in nature.
