Cyclopropane is more reactive than most cycloalkanes. What factors lead to cyclopropane being less stable than the other cycloalkanes

Answers

Answer: The factor that lead to cyclopropane being less stable than the other cycloalkanes is the presence of a RING STRAIN.

Explanation:

In organic chemistry, the end carbon atoms of an open aliphatic chain can join together to form a closed system or ring to form cycloalkanes. Such compounds are known as cyclic compounds. Examples include cyclopropane, cyclobutane, cyclopentane and many among others.

Cyclopropane is less stable than other cycloalkanes mentioned above because of the presence of ring strain in its structural arrangement. The ring strain is the spatial orientation of atoms of the cycloalkane compounds which tend to give off a very high and non favourable energy. The release of heat energy which is stored in the bonds and molecules cause the ring to be UNSTABLE and REACTIVE.

The presence of the ring strain affects mainly the structures and the conformational function of the smaller cycloalkanes. cyclopropane, which is the smallest cycloalkane than the rest mentioned above, contains only 3 carbons with a small ring.

explain how the solid liquid line in the phase diagram of water differs in character from the solid liquid line in the phase diagrams of most other substances such as CO2

Answers

Answer:

The solid-liquid line in the water phase diagram has a negative slope, whereas for most other substances it has a positive slope.

The ice has a lower density as compared to water still they have in the solid phase.

Reason how the  solid-liquid line in the phase diagram as compared to other:

In the solid-liquid line in the water phase diagram it contains the negative slope. While the most other substance should have the positive slope.

Also, when the pressure is applied so the higher density should be favored. In the water, the highest density phase should be likely the liquid water.

What will be the pH change when 20.0 mL of 0.100 M NaOH is added to 80.0 mL of a buffer solution consisting of 0.163 M NH3 and 0.188 M NH4Cl

Answers

Answer:

[tex]pH=9.32[/tex]

Explanation:

Hello there!

In this case, according to the given scenario, it turns out necessary for us to realize that the addition of NaOH consumes the conjugate base, NH4Cl, and produces more base, NH3; that is why the reaction taking place is:

[tex]NH_4^++OH^-\rightarrow NH_3+H_2O[/tex]

Thus, the reacting moles of ammonium and hydroxide ions are:

[tex]n_{NH_4^+}=0.0800L*0.188mol/L=0.01504mol\\\\n_{OH^-}=0.0200L*0.100mol/L=0.00200mol[/tex]

Thus, the resulting moles of ammonium and ammonia are respectively:

[tex]n_{NH_4^+}=0.01504mol-0.00200mol=0.01304mol\\\\n_{OH^-}=0.0800L*0.163mol/L+0.00200mol=0.01504mol[/tex]

Then, by using the Henderson-Hasselbach equation and recalling the pKb of ammonia (4.74), we first calculate the pOH as follows:

[tex]pOH=pKb+log(\frac{n_{NH_4^+}}{n_{NH_3}} )\\\\pOH=4.74+log(\frac{0.01304mol}{0.01504mol} )\\\\pOH=4.68[/tex]

And finally the pH:

[tex]pH=14-4.68\\\\pH=9.32[/tex]

A mixture of sulfuric acid and nitric acid will produce small quantities of the nitronium ion (NO2 ): The nitronium ion has a central nitrogen atom with a positive charge double bonded to two oxygen atoms on both sides. Each oxygen atom carries two lone pairs of electrons. Does the nitronium ion have any significant resonance structures

Answers

Answer:

A mixture of sulfuric acid and nitric acid will produce small quantities of the nitronium ion (NO2 ): The nitronium ion has a central nitrogen atom with a positive charge double bonded to two oxygen atoms on both sides. Each oxygen atom carries two lone pairs of electrons. Does the nitronium ion have any significant resonance structures?

Explanation:

The structure of nitronium ion is shown below:

Any molecule to exhibit resonance, it should have alternating double bonds.

Resonance is the phenomenon in which the structure of a molecule can be represented in two or more forms and each form is called canonical form.

The canonical forms do not differ in the position of atoms and they differ only in the position of double bonds.

For the given molecule, there are no alternating double bonds.

Hence, nitronium ion does not exhibit any significant resonance structures.

3CaCl2 + 2AlF3 --> 3CaF2 + 2AlCl3 3CaCl2 + 2AlF3 --> 3CaF2 + 2AlCl3 How many grams of CaF2 will form from 36.5 grams of AlF3?

Answers

Answer:

32.1 g

Explanation:

3CaCl₂ + 2AlF₃ → 3CaF₂ + 2AlCl₃

First we convert 36.5 g of AlF₃ into moles, using its molar mass:

36.5 g ÷ 133.34 g/mol = 0.274 mol AlF₃

Then we convert 0.274 moles of AlF₃ into moles of CaF₂, using the stoichiometric coefficients of the reaction:

0.274 mol AlF₃ * [tex]\frac{3molCaF_2}{2molAlF_3}[/tex] = 0.411 mol CaF₂

Finally we convert 0.411 moles of CaF₂ into grams, using its molar mass:

0.411 mol * 78.07 g/mol = 32.1 g

Answer:

[tex]Y_A=92.1\%\\\\Y_B=89.6\%[/tex]

Explanation:

Hello there!

In this case, according to the given chemical equation for the reaction for the production of potassium permanganate, we can see a 2:2 mole ratio of this product to the starting manganese (II) oxide, which means, we can calculate the theoretical yield of the former via stoichiometry:

[tex]m_{KMnO_4}=50.0gMnO_2*\frac{1molMnO_2}{86.94gMnO_2}*\frac{2molKMnO_4}{2molMnO_2} *\frac{158.034gKMnO_4}{1molKMnO_4} \\\\m_{KMnO_4}=90.9gKMnO_4[/tex]

Now, we are able to compute the percent yields, by using the actual yield each scientist got:

[tex]Y_A=\frac{83.67g}{90.9g} *100\%=92.1\%\\\\Y_B=\frac{81.35g}{90.9g} *100\%=89.6\%[/tex]

"A space shuttle travels around the Earth at a constant speed of 28000 kilometers per hour. If it takes 90 minutes to complete one orbit, how far is its journey around Earth?
"

Answers

Answer:

42000km

Explanation:

Average Speed (v) can be calculated using the formula as follows:

Average speed = distance (d) ÷ time (t)

According to this question, a space shuttle travels around the Earth at a constant speed of 28000 km/hr in 90 minutes.

Since 60 minutes = 1 hr

90 minutes = 90/60

= 3/2 or 1.5hours.

Using speed = distance/time

Distance (km) = speed × time

Distance = 28000 km/hr × 1.5hr

Distance = 42000km

Pressure is simply defined as the force per unit area. Mathematically, it is expressed as:

Pressure (P) = Force (F) / Area (A)

P = F/A

With the above formula, we can obtain the pressure exerted by the man on the ground. This can be obtained as follow:

Force (F) = 450 N

Area (A) = 0.0015 m²

Pressure (P) =?

P = F/A

P = 450 /0.0015

P = 3×10⁵ N/m²

Thus, the pressure exerted by the man on the ground is 3×10⁵ N/m².

54.56 g of water at 80.4 oC is added to a calorimeter that contains 47.24 g of water at 40 oC. If the final temperature of the system is 59.4 oC, what is the calorimeter constant (C calorimeter)

Answers

Answer:

49.5J/°C

Explanation:

The hot water lost some energy that is gained for cold water and the calorimeter.

The equation is:

Q(Hot water) = Q(Cold water) + Q(Calorimeter)

Where:

Q(Hot water) = S*m*ΔT = 4.184J/g°C*54.56g*(80.4°C-59.4°C) = 4794J

Q(Cold water) = S*m*ΔT = 4.184J/g°C*47.24g*(59.4°C-40°C) = 3834J

That means the heat gained by the calorimeter is

Q(Calorimeter) = 4794J - 3834J = 960J

The calorimeter constant is the heat gained per °C. The change in temperature of the calorimeter is:

59.4°C-40°C = 19.4°C

And calorimeter constant is:

960J/19.4°C =

49.5J/°C
