Approximately how much energy (in kJ) would be released during the formation of the bonds in 2.00 mol of acetone molecules

Answers

Answer 1

Answer:

7822 kJ

Explanation:

The formula for acetone is: CH3COCH3

From the standard bond energy(enthalpy):

C - H bond = 412

C - C bond = 348

C = O bond = 743

From the structure of an acetone

C is bonded to H in six places;

so, for  C- H bond = 6 × 412 = 2472

C is only bonded to two other carbon atoms

For C - C bond = 2 × 348 = 696

Carbon is only doubly bonded to an oxygen atom

For C = O bond = 1 × 743 = 743

The total net energy bond in a mole = (2472 + 696 + 743) kJ/mol

= 3911 kJ/mol

Finally, in 2 moles of acetone, the required amount of energy will be:

= 3911 kJ/moles × 2 moles

= 7822 kJ

0.50 g of hydrogen chloride (HCl) is dissolved in water to make 4.0 L of solution. What is the pH of the resulting hydrochloric acid solution

Answers

Explanation:

Given the mass of HCl is ---- 0.50 g

The volume of solution is --- 4.0 L

To determine the pH of the resulting solution, follow the below-shown procedure:

1. Calculate the number of moles of HCl given by using the formula:

[tex]number of moles of a substance=\frac{given mass of the substance}{its molecular mass}[/tex]

2. Calculate the molarity of HCl.

3. Calculate pH of the solution using the formula:

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

Since HCl is a strong acid, it undergoes complete ionization when dissolved in water.

[tex]HCl(aq)->H^+(aq)+Cl^-(aq)[/tex]

Thus, [tex][HCl]=[H^+][/tex]

Calculation:

1. Number of moles of HCl given:

[tex]number of moles of a substance=\frac{given mass of the substance}{its molecular mass}\\=0.50g/36.5g/mol\\=0.0137mol[/tex]

2. Concentration of HCl:

[tex]Molarity of HCl=\frac{number of moles of HCl}{its molar mass}\\=\frac{0.0137 mol}{4.0 L} \\= 0.003425 M[/tex]

3. pH of the solution:

[tex]pH=-log[H^+]\\=-log(0.003425)\\=2.47[/tex]

Hence, pH of the given solution is 2.47.

The rusting of iron is spontaneous at low temperatures.

Explanation:

The given chemical reaction is:

4Fe(s) + 3O2(g) ----> 2Fe2O3(s) [rust]

The rusting of iron is a chemical reaction in which iron reacts with oxygen in presence of moisture and forms iron oxide.

Poly(ethylene terephthalate) (PET), which has glass transition (Tg) and crystalline melting (Tm) temperature of 69 and 267 °C, respectively, can exist in a number of different states depending upon temperature and thermal history. Thus, it is possible to prepare materials that are semicrystalline with amorphous regions that are either glassy or rubbery and amorphous materials that are glassy, rubbery or melts. Consider a sample of PET cooled rapidly from 300 °C (state A) to room temperature. The resulting material is rigid and perfectly transparent (state B). The sample is then heated to 100 °C and maintained at this temperature, during which time is gradually becomes translucent (state C). It is then cooled to room temperature, where it is again observed to be translucent (state D).

Answers

Answer:

Following are the solution to the given points:

Explanation:

For point A:

The sample cooking (PET) is between 300°C and room temperature.Now in nature, the substance is exceedingly stiff.Samples of PET up to 100°C were heated and stayed on equal footing.Now it has cooled off the same sample below 100° C and we may see how it is again TRASNEPARENT in nature.

For point B:

In point 3, the mixture was added to 100°C, which implies that the granular material flows and deforms, enabling it to become elongated. This is termed solid-state crystalline such that grains are flexible, but this material contaminates numerous little crystalline that has spheres when we cool down in point  4 polymers. It forms therefore an unstructured solid, which then in point 4 is higher in particles and less pliable in orderly atoms.

For point C:

In point 2, the specimen gets forced at room temperature to organize a huge molecule in an ordinary and crystal fashion and therefore is transparent due to highly crystalline atoms in point 2 of the PET sample.

In point 4, however, we notice how amorphous, firm but not crystalline develops. It's why light tends to disperse over many cereal limits, since many microscopic crystallines, therefore dispersion, PET in point 4 is translucent.

A rectangular piece of plastic has a width of 4.2 cm, a height of 1.9 cm and a length of 8.8 cm. If the mass of the plastic rectangle is 64.6 g, what is its density in g/mL?

Answers

Answer:

0.92g/mL

Explanation:

Density of a substance is calculated as follows:

Density = mass (m) ÷ volume (V)

According to this question, a rectangular piece of plastic has a width of 4.2 cm, a height of 1.9 cm and a length of 8.8 cm. Using the formula; L × W × H, the volume of the plastic can be calculated

V = L × W × H

V = 8.8 × 4.2 × 1.9

V = 70.2cm³

The mass of the plastic is 64.6g, hence, its density is:

Density = 64.6g ÷ 70.2cm³

Density of the rectangular plastic = 0.92g/cm³ or 0.92g/mL

A sample of oxygen gas has a volume of 89.6 L at STP. How many moles of oxygen gas are present ?

Answers

Answer:

89,6/22,4 =4(mol)

Explanation:

There are approximately 1.089 moles of oxygen gas present in the sample at STP.

At STP (Standard Temperature and Pressure), the conditions are defined as follows:

Temperature (T) = 0 degrees Celsius = 273.15 Kelvin

Pressure (P) = 1 atmosphere (atm) = 101.325 kPa = 1013.25 hPa

Now, to find the number of moles of oxygen gas (O2) present in the sample, we can use the ideal gas law:

PV = nRT

Where:

P = pressure (in atm)

V = volume (in liters)

n = number of moles

R = ideal gas constant = 0.0821 L.atm/(mol.K)

T = temperature (in Kelvin)

Given:

V = 89.6 L (volume at STP)

T = 273.15 K (STP temperature)

Let's plug in the values and solve for n (number of moles):

n = PV / RT

n = (1 atm) × (89.6 L) / (0.0821 L.atm/(mol.K) × 273.15 K)

n = 1.089 moles

So, there are approximately 1.089 moles of oxygen gas present in the sample at STP.

Explanation:

First we convert 0.78 g of camphor to moles, using its molar mass:

0.78 g ÷ 152.23 g/mol = 0.00512 mol camphor

Then we convert 0.23 g of isoborneol to moles, using its molar mass:

0.23 g ÷ 154.25 g/mol = 0.00149 mol isoborneol

Finally we calculate the percent yield:

0.00149 mol / 0.00512 mol * 100% = 29.1%

Liquids form amorphous crystals while gases do not.
There are strong intermolecular forces between particles that make up liquids, but not gases.

Answers

Answer:

There are strong intermolecular forces between particles that make up liquids, but not gases.

Explanation:

Solids, liquids and gases are the three states of matter that exists. However, they possess varying properties that distinguishes them from one another. One of these properties is the strength of the intermolecular forces that hold their molecules together.

The intermolecular forces of each state of matter becomes weak in this order: solid>liquid>gas.

- Intermolecular forces in solid molecules are very strong, hence making them compact and well attached to each other.

- Intermolecular forces in liquid molecules are not too strong, hence, cannot exist in a fixed position but tend to flow.

- Intermolecular forces in gaseous molecules are very weak, hence, gases can move easily and rapidly in any given space.

Why the normal selectivity expected for bromination is not observed

On the basis of selectivity and applying the Arrhenius equation the greater the difference between the activation energies the more the selectivity.

as seen in the formation of primary and secondary radicals in the Bromine radical formation. this difference is caused mainly by the propagation step ( exothermic ) . But the main reason why the the usual selectivity of bromination is not observed is because it Bromine radical formation is carried out in the presence of Br₂ and Cl₂ ( this causes the difference in activation energy to be reduced )

Make me another one, or I'm going to school on an empty stomach.(Mrs. Jones sighs and makes him another piece of toast. Jake quickly eats it and walks away without thanking her. Mrs. Jones continues with her work. She hears her daughter yelling.)MRS. JONES: What is it, Clara?CLARA: Mom, come have a look at what Mattie has done.(Mrs. Jones wipes her soapy hands and walks into the living room. She is stunned when she sees the white walls with drawings all over them. She finds her youngest son, Mattie, behind the couch, busy making a drawing on the wall. Without bothering to notice what he is drawing, she drags him out from behind the couch.)MRS. JONES: Mattie, look at what you've done. How could you make such a mess? You've ruined the walls.MATTIE: But, mom, I was just . . .MRS. JONES: Be quiet, Mattie. Day after day I have to look after the three of you, and I never get any appreciation. And now you've gone and scribbled all over the walls. Do you know how long it'll take me to clean up this mess?MATTIE: I'm sorry, mom, I didnt mean to.MRS. JONES: Sorry doesn't change the fact that you've made a big mess.(Mattie looks like he is about to cry.)MRS. JONES: Don't cry, Mattie. Crying is not the solution to our problems.MATTIE: I'm sorry. I'll clean it up right away, mom.MRS. JONES: Yes, you better. Now go and get some soap and a scrubber and get to cleaning.(Mattie looks discouraged as he leaves the room. Mrs. Jones is still furious as she watches him go. She then turns to the wall and her expression changes into one of shock.)MRS. JONES: (to herself) What? Its a drawing of Mattie and me, and the words "I love you, mom" are written below it.(Mattie returns to the room with the soap and scrubber. She looks at him with tear-filled eyes and hugs him tightly to her as he reaches her.)MRS. JONES: I'm sorry too, Mattie. help me out please (geometry)
