Which of the following is (are) formed in the reaction between ethyl butanoate and ethyl amine?
Select one:
O a. ethanol O b. 1-butanol O c. N-ethylbutanamide O d. both A and C O e, both B and C

Answers

Answer 1

Both B and C reaction between ethyl butanoate and ethyl amine.

What is amines?

Amines are organic compounds derived from ammonia by replacing one, two, or all three hydrogen atoms with alkyl or aryl groups. They are classified as primary, secondary, and tertiary amines depending on the number of carbon atoms connected to the nitrogen atom. Amines have a strong smell, and many of them are used in the production of pharmaceuticals, dyes, and other products. Amines are also important intermediates in the synthesis of many organic compounds.

In the reaction between ethyl butanoate and ethyl amine, both 1-butanol and N-ethylbutanamide are formed. Ethyl butanoate is an ester, which consists of an alcohol and an acid joined together. When ethyl amine is added, the ester breaks apart, releasing the acid and alcohol components. The acid component is then protonated by the amine, forming N-ethylbutanamide. The alcohol component, which is 1-butanol, is also released in the reaction.

Explanation:

In Claire's test, the weight of vehicle 1 is either equal to or greater than the weight of vehicle 2, so it was sufficient to push it down the cliff.  In the film Ice word revenge, the weight of vehicle 1 is less than the weight of vehicle 2, it is not sufficient to make it fall off the cliff ( Note: Looking exactly the same in the movie, as Claire claimed, does not mean they have the same mass). Therefore if Claire wants a collision that will not make the vehicle 2 fall off the cliff, he should collide it with a vehicle of lesser mass/weight.

Sodium chloride (NaCl) is commonly used to melt ice on roads during the winter. Calcium chloride (CaCl2) is sometimes used for this purpose too. Let us compare the effectiveness of equal masses of these two compounds in lowering the freezing point of water by calculating the freezing point depression of solutions containing 220. g of each salt in 1.00 kg of water. (An advantage of is that it acts more quickly because it is hygroscopic, that is, it absorbs moisture from the air to create a solution and begin the process. A disadvantage is that this compound is more costly.) Assume full dissociation of ionic compounds. Kfp(H2O)= -1.86 °C/m.

ΔTfp= _________°C for NaCl
ΔTfp=_________ °C for CaCl2

Answers

Answer:

[tex]\Delta Tfp_{NaCl}= -14.0\°C\\\\\Delta Tfp_{CaCl_2}=-11.1\°C[/tex]

Explanation:

Hello!

In this case, since the freezing point depression caused by the addition of a solute, we use the following formula:

[tex]\Delta Tfp= i*m*Kfp[/tex]

Thus, we first need to compute the molality of each solute, as shown below:

[tex]m_{NaCl}=\frac{220.g/(58.44g/mol)}{1.00kg} =3.76m\\\\m_{CaCl_2}=\frac{220.g/(110.98g/mol)}{1.00kg} =1.98m[/tex]

Next, since NaCl has two ionic species, one Na⁺ and one Cl⁻, and CaCl₂ three, one Ca²⁺ and two Cl⁻, the van't Hoff's factors are 2 and 3 respectively, therefore the freezing point depressions turn out:

[tex]\Delta Tfp_{NaCl}= 2*3.76m*-1.86\°C/m=-14.0\°C\\\\\Delta Tfp_{CaCl_2}= 3*1.98m*-1.86\°C/m=-11.1\°C[/tex]

It means that CaCl₂ is still better than NaCl because produces involves a higher melting point for the ice, so it would melt faster.

For the following reaction, 14.3 grams of phosphorus (P4) are allowed to react with 32.1 grams of chlorine gas. phosphorus (P4) (s) + chlorine (g) phosphorus trichloride (l) What is the maximum amount of phosphorus trichloride that can be formed? grams What is the FORMULA for the limiting reagent? What amount of the excess reagent remains after the reaction is complete? grams

Answers

Answer:

Limiting reactant: Cl2.

Max mass of PCl3 = 41.44 g.

P4 leftover = 5.51 g.

Explanation:

Hello!

In this case, since the undergoing chemical reaction is:

[tex]P_4+6Cl_2\rightarrow 4PCl_3[/tex]

In order to compute the maximum amount of PCl3, it is necessary to compute the grams of this product produced by each reactant, just as shown below, whereas molar masses and mole ratios are used:

[tex]m_{PCl_3}^{by\ P_4}=14.3gP_4*\frac{1molP_4}{123.89gP_4} *\frac{4molPCl_3}{1molP_4} *\frac{137.33gPCl_3}{1molPCl_3} =63.41gPCl_3\\\\m_{PCl_3}^{by\ Cl_2}=32.1gCl_2*\frac{1molCl_2}{70.91gCl_2} *\frac{4molPCl_3}{6molCl_2} *\frac{137.33gPCl_3}{1molPCl_3} =41.44gPCl_3[/tex]

Thus, since chlorine gas yields fewer grams of PCl3 than P4 we infer Cl2 is the limiting reactant and 63.41 grams of PCl3 product are yielded.

Finally, for the excess reactant, we see a difference of 63.41-41.44=21.97g, so we can compute of the leftover of P4 as follows:

[tex]m_{P_4}^{leftover}=21.97gPCl_3*\frac{1molPCl_3}{137gPCl_3} *\frac{1molP_4}{4molPCl_3} *\frac{137.33gP_4}{1molP_4} =5.5gP_4[/tex]

In the benzene molecule, carbon atoms form a ring with alternating single and double bonds in between each of them. Each carbon atom forms one σ bond with one carbon atom and one σ and one π bond with another. The π bonding electrons are delocalized over the entire molecule. Thus, benzene is a resonance hybrid of two equivalent structures, and the single and double bonds oscillate from one position to the other.

Required:
Calculate the bond order for one carbon-carbon bond in the benzene molecule, taking σ and π bonding into consideration.

Answers

Answer:

1.5

Explanation:

From;

BO = ½(B – A)

BO= Bond order

B= Number of bonding electrons

A = Number of antibonding electrons

For the sigma bonds, there are 2 bonding electrons and 0 nonbonding electrons.

σ BO = ½(B – A) = ½(2 – 0) = 1

π bond order for 6 C-C bonds;

π BO = ½(B – A) = ½(6 – 0) = 3

For each  π bond, BO = 3/6 = 0.5.

Hence, for a single C-C bond in benzene, the total Bond order = σ + π = 1 + 0.5 = 1.5.

A steel cylinder contains 4.5 mol of Xenon gas at a pressure of 5 atm and a temperature of 77 degrees Celsius. What is the volume of the Xenon tank?

Answers

Answer:

3 × 10 L

Explanation:

Step 1: Given and required data

Moles of Xenon gas (n): 4.5 molPressure of the gas (P): 5 atmTemperature (T): 77 °CIdeal gas constant (R): 0.082 atm.L/mol.K

Step 2: Convert "T" to Kelvin

When working with gases, we need to use the absolute temperature. We can convert Celsius to Kelvin using the following expression.

K = °C + 273.15

K = 77°C + 273.15 = 350 K

Step 3: Calculate the volume (V) of the tank

We can calculate the volume occupied by the gas using the ideal gas equation.

P × V = n × R × T

V = n × R × T/P

V = 4.5 mol × (0.082 atm.L/mol.K) × 350 K/5 atm = 3 × 10 L

what is the relationship between temperature and kinetic energy?

Answers

Answer:

Temperature is directly proportional to the kinetic energy of the atoms that a body is made of. This relation is valid concerning the velocities relative to the center of mass of the body. In other words, concerted movements like translation and rotation do not affect temperature.

Explanation:

Answer:

As stated in the kinetic-molecular theory, the temperature of a substance is related to the average kinetic energy of the particles of that substance. When a substance is heated, some of the absorbed energy is stored within the particles, while some of the energy increases the motion of the particles.

Assuming each solution to be 0.10 M , rank the following aqueous solutions in order of decreasing pH.Rank the solutions from the highest to lowest pH. To rank items as equivalent, overlap themN2H2Ba(OH)2HOCLNAOHHCL

Answers

Answer:

Ba(OH)₂ > NaOH >N₂H₂  > HOCl > HCl

Explanation:

To get a better understanding of this, we need to know what's the meaning of the pH values.

The pH value of any compound basically gives us information of how acidic or basic is a compound. If this value is higher (>7), means major basicity; if this number is lower (<7) means major acidity in the compound.

According to this, a strong acid would be the one with the lowest pH, and a strong base would be the one with the highest pH.

Among the 5 compounds we have here, only 2 of them are acid, and the rest is basic, so we can assume that both acid would have the lower pH, it's up to us to see which of them have the lowest pH.

To do that, we can use the following expression:

pH = -log[H⁺]

If all solutions have a concentration of 0.10, then the pH would be:

HCl:

pH = -log(0.1) = 1

HOCL:

This one is a weak acid, so it's not completely dissociated in solution and the [H⁺] would be <0.1 M. As its a weak acid, we can assume that it's pH would be near 4, 5 or 6. We cannot know with all certain, because we need the Ka of this acid, and see the dissociation of the acid in solution, but for this case, it's fine and HCl is one of the strongest known acid.

In this case the order is: HOCl > HCl

For the bases, we have 3 bases, 2 of them are strong bases, and 1 of them is a weak base so it doesn't dissociate completely (N₂H₂), so this would have the lowest pH among the bases. In the case of bases, we calculate pOH, (Same formula as before) and then, we substract 14 from the value of pOH. As for the other two:

Ba(OH)₂:

Concentration would be double because we have 2 OH, so:

[OH⁻] = 2 * 0.1 = 0.2 M

pOH = -log(0.2) = 0.69

pH = 14 - 0.69 = 13.31

NaOH:

pOH = -log(0.1) = 1

pH = 14 - 1 = 13

Therefore, Ba(OH)₂ is stronger than NaOH and N₂H₂. So, our order would be:

Ba(OH)₂ > NaOH >N₂H₂  > HOCl > HCl

Hope this helps

Answer:

Explanation:

Follow the sequence ...

%/100wt => grams/100wt => moles => mole ratio => reduce mole ratio (divide by smaller mole value) => empirical ratio.

Note: If the above calculation comes out with a fraction (for most textbook problems) do the following:

--.25 => multiply empirical ratio by 4

--.50 => multiply empirical ratio by 2

--.75 => multiply empirical ratio by 4

Or, if initial data is given in grams, convert to %/100wt. (example at end of problem)

This Problem:  

         %/100wt.   grams         moles =mass/formula wt.

%C = 75.95% => 75.95g => 75.95g/12.0107g·mol⁻¹ = 6.325 mole OS

%N = 17.72% =>  17.72g => 17.72g/14.0067g·mol⁻¹ = 1.2651 mole N  

%H =  6.33% =>   6.33g =>  6.33g/1.00794g·mol⁻¹ = 6.28 mol H              

(∑  =   100%    | assume 100g cpd  => ( grams => 100g compound would contain 75.95g C, 17.72g N & 6.33g H )

=> mole ratio =>  C : N : H => 6.3235 : 1.2651 : 6.28  

=> reduce mole ratio ( divide by smaller mole value ) ...

=> 6.3235/1.2651 : 1.2651/1.2651 : 6.28/1.2651 =>  empirical ratio is => 5:1:5

empirical formula => C₅NH₅

empirical formula wt. = 5C + 1N + 5H = 5(12) + 1(14) + 5(1) = 79

=> molecular ratio (n) => molecular wt (given) = N · empirical formula wt

=> N =  molecular wt / empirical wt = 240/79 = 3

∴ Molecular Formula is =>  C₅NH₅ X 3 => C₁₅N₃H₁₅

Assume an oxide of Osmium (compd wt) = 2.89 grams contains 2.16 gram Osmium, what is the empirical formula?

Use given mass values to calculate %/100wt then use the sequence

% => grams => moles => reduce => emp. ratio => emp. formula

%Os = 2.16g/2.89g x 100% = 74.74%

%Oxy = [(2.89g -2.16g)/2.89] x 100% = 25.26% or use 100% - 74.74% = 25.26%

%  => g => moles => reduce => emp formula

%Os   = 74.74% => 74.74g => 74.74g/190.23g·mol⁻¹ = 0.3929 mol Os

%Oxy = 25.26% => 25.26g => 25.26g/16g·mol⁻¹ = 1.5788 mole Oxy

Reduce mole ratio (divide by smaller mole value) => empirical ratioo

=> Os:Oxy => 0.3929/0.3929 : 1.5788/0.3929 = 1 : 4

An industrial synthesis of urea obtains 87.5 kg of urea upon reaction of 68.2 kg of ammonia

with 105 kg of carbon dioxide. Determine the limiting reactant, theoretical yield of urea and percent yeild for the reaction​

Answers

Answer:

NH₃ is the limiting reactant.Theoretical yield = 120 kg% yield = 72.9 %

Explanation:

2NH₃ (aq) + CO₂ (aq) → CH₄N₂O (aq) + H₂O (l)

First we convert the given masses of reactants to moles, using their respective molar masses:

68.2 kg NH₃ ÷ 17 kg/kmol = 4.01 kmol NH₃105 kg CO₂ ÷ 44 kg/kmol = 2.39 kmol CO₂

2.39 kmol of CO₂ would react completely with (2.39 * 2) 4.78 kmol of NH₃. There are not as many NH₃ kmoles so NH₃ is the limiting reactant.

We calculate how much urea would form with a 100% yield, using the moles of limiting reactant:

4.01 kmol NH₃ * [tex]\frac{1kmolCH_4N_2O}{2kmolNH_3}[/tex] = 2.00 kmol CH₄N₂O

We convert that amount to kg:

2.00 kmol CH₄N₂O * 60 kg/kmol = 120 kg CH₄N₂O

Finally we calculate the percent yield:

87.5 kg / 120 kg * 100% = 72.9 %

Under the new tax law, the equipment is eligible for 100% bonus deprecation at t = 0, so it will be fully depreciated at the time of purchase. The equipment will have no salvage value at the end of the projects four-year life. Fox pays a constant tax rate of 25%, and it has a weighted average cost of capital (WACC) of 11%. Determine what the projects net present value (NPV) would be under the new tax law.Which of the following most closely approximates what the projects net present value (NPV) would be under the new tax law?(Hint: Round your final answer to two decimal places and choose the value that most closely matches your answer.)$90,392.12$80,348.55$120,522.83$100,435.69Which of the of the following most closely approximates what the projects NPV would be when using straight-line depreciation?
