which is a difference between butyne and cyclobutyne? group of answer choices cyclobutyne does not exist. butyne's multiple bond is interior, cyclobutyne is not between interior carbons. cyclobutyne burns much hotter than butyne because of the greater unsaturation. both b and c are differences between the molecules.

Answers

Answer 1

Cyclobutyne does not exist. A hydrocarbon molecule called cyclobutyne has a triple bond inside of a ring with four carbon atoms.

Due to its high ring strain, this cycloalkyne is extremely unstable and hasn't been isolated in its purest form.

What is butyne ?

Organic compound butyne has the chemical formula HC2CH2CH3. It is a flammable, colourless gas. 1-Butyne takes part in processes that are common for terminal alkynes, such as hydrogenation, condensation with formaldehyde, and alkyne metathesis.

Due of its extremely low torsional barrier and the difficulty in identifying it using high-resolution infrared spectroscopy, 2-butyne is of interest to physical chemists.

Cycloalkenes include cyclobutene. It offers potential for research but no immediate applications. It is an effortlessly condensible colourless gas. In a contemporary synthesis, cyclobutanol is dehydrated twice. The ammonium salt OH was first thermolyzed to create the chemical.

Cycloalkanes are monocyclic saturated hydrocarbons in organic chemistry. To put it another way, all of the carbon-carbon bonds in a cycloalkane's structure are single and it only contains hydrogen and carbon atoms grouped in a configuration with a single ring.

When a cycloalkane has more than 20 carbon atoms, it is often referred to as a cycloparaffin. The isomers of alkenes make up all cycloalkanes.

Nothing like cyclobutyne exists. Cyclobutyne, a hydrocarbon molecule, features a triple bond inside of a ring made up of four carbon atoms. This cycloalkyne hasn't been isolated in its purest form because of its high ring strain, which makes it very unstable.

Describe butyne.?

Butyne is an organic molecule with the formula HC2CH2CH3, according to chemistry. It is a flammable, colorless gas. 1-Butyne takes part in processes that are typical for terminal alkynes, such as hydrogenation, condensation with formaldehyde, and alkyne metathesis.

Because of its very low torsional barrier and the difficulty in locating it using high-resolution infrared spectroscopy, 2-butyne is of interest to physical chemists.

One of the cycloalkenes is cyclobutene. Although it might be studied, there are currently no applications in real life. It is an easily condensable colorless gas. In a contemporary synthesis, cyclobutanol passes through two stages of dehydration. The ammonium salt OH was first thermolyzed to create the chemical.

Answers

Answer:

Explanation:

To recognize what element this is, we can simply look at the last orbital (5d9) and go to the periodic table and see what element is in that final orbital.

We go to row 6 (because of the 6s orbital at the beginning of this row) and then we see that our 6s orbital is full with 2 electrons, then our 4f orbital is full with 14 electrons, and our 5d orbital is not full where we only have 9 electrons instead of 10.

We then go to our 5d orbital and count 9 times into that orbital and end up with our final element being Gold (Au).

a chemist has three different acid solutions. the first acid solution contains 25 % acid, the second contains 45 % and the third contains 85 % . he wants to use all three solutions to obtain a mixture of 95 liters containing 65 % acid, using 3 times as much of the 85 % solution as the 45 % solution. how many liters of each solution should be used?

Answers

First acid solution contains 19 liters of 25% acid, second acid contains  19 liters of 45% acid, and the third contains 57 liters of 45% acid.

Let us take x as the liters of 25% acid, y as the liters of 45% acid, and z as the liters of 85% acid.

From this we get an equation:

x + y + z = 95    

0.25x + 0.45y + 0.85z = (0.65)95

By equating both the equation we have:

y + 3z = 190

y = 190 - 3z  

It is given that z = 3y

Solve the system of equations using eliminating or substituting we get:

x + y + z = 95

x + y + 3y = 95

x  + 4y = 95

x = 95- 4y

0.25( 95 - 4y ) + 0.45y + 0.85(3y) = (0.65) 95

23.75- y + 0.45y  + 2.55y = 61.75  

2y = 38

y = 19

x = 95 - 4y

  = 95 -76

   = 19

z = 3y

 = 3× 19

 = 57

Therefore the chemist needs 19 liters of 25% acid, 19 liters of 25% acid and, 57 liters of 85% acid.

You should develop the TLC (thin layer chromatography) plate orthogonally (under a 90-degree angle) to the original direction of development (along its width, while the original development was along the length of the TLC plate).

This technique is called 2D TLC (two-dimensional thin layer chromatography) and is usually employed to analyze and preparatively separate very complex mixtures that cannot be separated using only one solvent system. The initial development (along the length of the TLC plate) enables crude separation into groups of compounds with similar retention factor (Rf). These groups can then be further separated using a different solvent system by developing the same TLC plate along its width.

What is the theory of the ideal gas law?

The relationship between a gas's pressure P, volume V, and temperature T in the range of low pressures and high temperatures, when the gas's molecules move virtually independently of one another, is known as the ideal gas law, also known as the perfect gas law.

Briefing:

T[tex]_N_e[/tex]​ =30⁰C=(30+273)K=303K

T[tex]_N_2[/tex]​​ =20⁰C=(20+273)K=293K

P[tex]_N_2[/tex] ​ =1.0atm

Ideal gas constant - R=0.0821L⋅atm/ K⋅ mol

The molar mass of

Neon - M[tex]_N_e[/tex]​​=20.18g/mol

Nitrogen - M[tex]_N_2[/tex]​​ ​ =2⋅14.007g/mol=28.014g/mol

Determine the pressure P[tex]_N_e[/tex]​  required for neon at 30⁰C to have the same density (d) as nitrogen at 20⁰C.

d = m/V

We know that

n = m/M

Using the ideal gas law, we get

PV = nRT

PV = m/M *RT

Since

PM/RT = m/V =d

d =  PM/RT

d= [tex]\frac{P_{N_2} M_{N_2}}{R T_{N_2}}[/tex]

d = 1.0 atm * 28.014 g/mol/0.0821L atm/K mol 293K

d = 1.2 g//L

Since both gases have the same density, we can calculate the pressure of neon gas, using

[tex]d=\frac{P_{N e} M_{N e}}{R T_{N e}}[/tex]

[tex]P_{N e}=\frac{d R T_{N e}}{M_{N e}}[/tex]

Which of the following compounds contains the greatest percent by mass of nitrogen

Answers

Answer:

[tex]A\colon NH_3[/tex]

Explanation:

Here, we want to get which of the compounds have the highest percentage by mass of nitrogen

What we have to do here is to divide the mass of nitrogen atoms in the compound by the molecular mass of the compound

a) NH3

The atomic mass of nitrogen is 14 amu, the atomic mass of hydrogen is 1 amu

The molar mass is thus 14 + 3(1) = 17 g/mol

The percentage by mass of nitrogen will be

14/17 * 100 = 82.35 %

b) HCN

The atomic mass of carbon is 12 amu

Thus, we have the molar mass as

1 + 12 + 14 = 27 g/mol

Percentage of nitrogen by mass will be : 14/27 * 100 = 51.85 %

c) For N2O

The atomic mass of oxygen is 16 amu

The molar mass of the compound will be 14(2) + 16 = 44 g/mol

Percentage of nitrogen by mass will be = 28/44 * 100 = 63.64 %

d) NI3

The atomic mass of iodine is 127 g/mol

So the molar mass of the compound will be:

14 + 3(127) = 395 g/mol

Percentage by mass of nutrogen will be

14/395 * 100 = 3.54 %

From what we have, the highest percentage by mass of nitrogen is 82.35 % and that belongs to ammonia (NH3)

when 27.64 g of a hydrocarbon is burned in a bomb calorimeter, the temperature increases by 54.91c. if the heat capacity of the calorimeter is 68.5 j/c and the sample is submerged in 1000 ml of water, how much heat (in kj) was produced by the hydrocarbon combustion?

Answers

By using the data given in the text and the specific heat capacity of water and its density, we can calculate that the amount of heat produced by hydrocarbon combustion was 233.6 kJ.

The heat released by hydrocarbon combustion is absorbed by the calorimeter and the water in it. To calculate the amount of heat (Q) produced by the combustion, we are going to use the specific heat capacity of water (c = 4.186 J/g°C), the heat capacity of the calorimeter (q = 68.5 J/°C) and the difference in temperature (ΔT = 54.91 °C):

heat absorbed by the calorimeter = ΔT*q

heat absorbed by water = ΔT*c*m

Q = ΔT*q + ΔT*c*m

m - the mass of water

To obtain the mass of water, we are going to use the volume (V = 1000 mL) of water and its density (d = 1.00 g/mL):

d = m/V ⇒ m = d * V

m = 1.00 g/mL * 1000 mL

m = 1000 g

Now we can plug all the known values in the formula for Q:

Q = 54.91 °C * 68.5 J/°C + 54.91 °C * 4.186 J/g°C * 1000 g

Q = 233,614.595 J
