Place the following substances in order of increasing vapor pressure at a given temperature.
a. NF3,
b. NH3,
c. BCl3.

Answers

Answer:

NH3 < NF3 < BCl3

Explanation:

The vapour pressure of a substance has something to do with the nature of intermolecular forces between its molecules. If the molecules of a substance are held together by strong intermolecular forces, the substance will display a low vapour pressure at a given temperature and vice versa.

Ammonia has the lowest vapour pressure because of strong intermolecular hydrogen bonds that hold its molecules together.

The trend for increasing vapor pressure will be:

NH₃<NF₃<BCl₃

We know that,

The stronger the intermolecular forces, the lower the vapor pressure, and the higher the boiling point.

Thus to solve this question we need to look the intermolecular attractions in the given molecules.

1. In ammonia molecule, since it is polar in nature. It exhibits, dipole-dipole interactions and also there is hydrogen bonding between nitrogen and hydrogen atoms. So these interactions are strongest  thus NH₃ will have lower value of vapor pressure.

2. Forces of attractions in NF₃ is also stronger in comparison to BCl₃ but weaker than NH₃ thus in terms of vapor pressure it will come after NH₃.

3. Lastly, in BCl₃ it is a non-polar molecule; it exhibits London forces which are the weakest thus it will have the higher value of vapor pressure.

Trend for intermolecular attraction:

ion-dipole>hydrogen bonding>dipole-dipole> London forces > Van der Waals forces

Therefore,

Increasing order of vapor pressure will be:

NH₃<NF₃<BCl₃

Which set contains non-equivalent members?A) enthalpy and heat contentB) endothermic reaction and +HC) exothermic reaction and -HD) kinetic energy and energy of motionE) high energy and high stability

Answers

Answer:

E

Explanation:

Here in this question, what we will do is to select which of the pairs that do not correlate.

A. Enthalpy and heat content

This two terms are at par with each other. By definition, the enthalpy of a system simply is the total amount of heat content it has.

B. Endothermic reaction and +H

These two terms are at par with each other. An endothermic reaction is one in which heat is absorbed from the surroundings. It has a positive value for the heat content i.e the enthalpy is positive and thus H is positive.

C. Exothermic reaction and -H

An exothermic reaction is one in which heat is released to the environment. It usually has a negative value for the enthalpy and thus the value of H is negative.

D. High energy and High Stability

These two terms are not at par. When an entity has or is of high energy, it is usually unstable. An entity at a higher energy level will not be stable until it goes to a lower level of energy.

Thus higher energy level is associated with lesser stability while lower energy levels are associated with higher stability. The lesser the energy of an entity, the higher its stability.

This makes the option our answer.

[tex]\°F=1.1x10^4\°F[/tex]

Explanation:

Hello,

In this case, for the calculation of the temperature in degree Celsius we subtract 273.15 to the given temperature in kelvins:

[tex]\°C=6100-273.15\\\\\°C=5.8x10^3\°C[/tex]

Next, by applying the following equation we compute it in degree Fahrenheit:

[tex]\°F=(5.8x10^{3}*9/5) + 32\\\\\°F=1.1x10^4\°F[/tex]

Clearly, since the initial unit has two significant figures the computed units also show two significant figures.

Rotation about a carbon-carbon double bond does not readily occur because: __________.1) the overlap of the p orbitals of the carbon-carbon π bond would be lost2) the double bond is much shorter and therefore more difficult to rotate3) the overlap of the sp2 orbitals of the carbon-carbon σ bond would be lost4) the double bond is much stronger and therefore more difficult to rotate

Answers

Answer:

1) The overlap of the p orbitals of the carbon-carbon π bond would be lost

Explanation:

Unlike simple bonds, a double bond can not rotate, since it is not possible to twist the ends of the molecule without breaking the π bond.

In the structure of but-2-ene present in the attachment, we can see the two isomers, cis and trans. These isomers cannot be interconverted by rotation around the carbon-carbon double bond without breaking the π bond.

The table below shows air pressure measurements taken at set altitudes above sea level. What fact about Earth’s atmosphere best explains this data according to the table? Question 3 options: As altitude increases in the atmosphere, temperature changes from layer to layer. As altitude increases, there is less air pushing down from above, which decreases the pressure. As altitude increases, the composition of the atmosphere changes so that lighter-weight gases make up the majority of the air. At higher altitudes, there is less water vapor in the air which changes the air pressure.

Answers

Answer: As altitude increases, there is less air pushing down from above, which decreases the pressure.

Explanation:

Atmospheric pressure is the result of air particles being pulled to the surface of the Earth by gravity. As they are pulled, they will exert more pressure on the Earth and this is what atmospheric pressure is.

It makes sense therefore that as we move higher into the atmosphere, the atmospheric pressure will decrease because less air particles are exerting pressure as we go further off the ground.

Another way to look at it is that there is air in the earth's atmosphere and all that air has weight that is pushing down on us. As we go higher into the atmosphere, there'll be less air pushing down on us so the weight will be less.

One gallon of gasoline in an automobiles engine produces on average 9.50 kg of carbon dioxide, which is a greenhouse gas; that is, it promotes the warming of Earth's atmosphere. Calculate the annual production of carbon dioxide in kilograms if there are exactly 40.0 million cars in the United States and each car covers a distance of 7930 mi at a consumption rate of 23.6 miles per gallon. Enter your answer in scientific notation.

Answers

Answer:

The value is [tex]U =1.3908 *10^{11} \ kg [/tex]

Explanation:

From the question we are told that

mass of carbon dioxide produced by one gallon of gasoline is [tex]m = 9.50 \ kg[/tex]

The number of cars is [tex]N = 40 \ million = 40 *10^{6} \ cars[/tex]

The distance covered by each car is [tex]d = 7930 \ mi[/tex]

The rate is [tex]R = 23.6 \ mi/ gallon[/tex]

Generally the amount of gasoline used by one car is mathematically represented as

[tex]G = \frac{d}{R}[/tex]

=> [tex]G = \frac{7930}{23.6}[/tex]

=> [tex]G = 366 \ gallons [/tex]

Generally the amount of gasoline used by N cars is

[tex]H = N * G[/tex]

=> [tex]H = 40*10^{6} * 366[/tex]

=> [tex]H = 1.464*10^{10} \ gallons [/tex]

Generally the annual production of carbon dioxide is mathematically represented as

[tex]U = m * H[/tex]

=> [tex]U =9.50 * 1.464*10^{10}[/tex]

=> [tex]U =1.3908 *10^{11} \ kg [/tex]

What is the pH of a weak acid that is 0.2% ionized in a 0.2 M solution?

Answers

Answer:

pH=3.40

Explanation:

For this question, we can start with the general ionization reaction of a general acid:

[tex]HA~<->~A^-~+~H^+[/tex]

The acids can produce the hydronium ion ([tex]H^+[/tex]). If we can to calculate the pH we have to use the equation:

[tex]pH=-Log[H^+][/tex]

So, if we want to calculate the pH value we have to know the concentration of the hydronium ion. For this, we can check the percentage of ionization. If we have 0.2 % of ionization, we will have only  0.2 % of hydronium ions from the initial concentration. In other words, we can calculate the concentration of [tex]H^+[/tex], if we do the 0.2% of the initial concentration, so:

[tex]0.2~M*\frac{0.2}{100}~=~0.0004~M[/tex]

With the concentration we can calculate the pH:

[tex]pH=-Log[0.0004~M]~=~3.40[/tex]

The pH value is 3.40

A 1.00-mole sample of C6H12O6 was placed in a vat with 100 g of yeast. If 32.3 grams of C2H5OH was obtained, what was the percent yield of C2H5OH?

Answers

Answer:

y = 35.06 %.

Explanation:

The reaction of fermentation is:

C₆H₁₂O₆  →  2C₂H₅OH + 2CO₂      (1)        

From the reaction (1) we have that 1 mol of C₆H₁₂O₆ produces 2 moles of C₂H₅OH, then the number of moles of C₂H₅OH is:

[tex]n = \frac{2 moles C_{2}H_{5}OH}{1 mol C_{6}H_{12}O_{6}}*1 mol C_{6}H_{12}O_{6} = 2 moles C_{2}H_{5}OH[/tex]

Now, we need to find the mass of C₂H₅OH:

[tex]m = n*M = 2 moles*46.07 g/mol = 92.14 g[/tex]  

Finally, the percent yield of C₂H₅OH is:

[tex] \% = \frac{32.3 g}{92.14 g}*100 = 35.06 \% [/tex]

Therefore, the percent yield of C₂H₅OH is 35.06 %.

I hope it helps you!

The percent yield of C2H5OH should be 35.06% also it have the 1.00 moles.

Calculation of the percent yield:

Since

The reaction of fermentation should be

C₆H₁₂O₆  →  2C₂H₅OH + 2CO₂      (1)        

Here  1 mol of C₆H₁₂O₆ generated 2 moles of C₂H₅OH, so the number of moles of C₂H₅OH should be

= 2 moles / 1mole * 1 mole

= 2 moles C₂H₅OH

So here the percent yield should be

= 32.3 / (2 * 4607)

= 32.3 / 92.14

= 35.06%

Hence, The percent yield of C2H5OH should be 35.06% also it have the 1.00 moles.
