a race car at the Daytona 500 zips around the track .its travel the first 80 kilometers in 0.4 hours. the next 114 kilometers take 0.6 . the following 80 kilometers take 0.4 hours to calculate the race car average speed.

Answers

Answer 1
The answer to this should be around 40
Answer 2

A race car at the Daytona 500 zips around the track its travel the first 80 km in 0.4 hours, the next 114km take 0.6, the following 80 km take 0.4, so the average speed is 195.71 km/hr.

How do we calculate the average speed?

Average speed of any body will be calculated by dividing the total time to cover the ditance from the total distance covered.

Total distance to cover = 80km + 114km + 80km = 274km

Total time to cover distance = 0.4hr + 0.6hr + 0.4hr = 1.4hr

Average speed of car = 274/1.4 = 195.71 km/hr

So, the average speed of car is 195.71km/hr

[tex]Zn^{2+}[/tex]

Explanation:

Hello,

In this case, since metals tend to lose electrons, they usually become the cations when chemical compounds are formed so the other element should be negative to allow their interactions to take place.

In such a way, since oxygen is known to be negatively charged as -2 and their subscripts are both 1, we infer that the oxidation state of zinc is +2, therefore, it is written as an ion as follows:

Is it possible for a diprotic acid to have Ka1?

Answers

Answer:

Yes, it is possible.

Explanation:

A diprotic acid is an acid that can release two protons. That's why it is called diprotic.

Monoprotic → Release one proton, for example Formic acid HCOOH

Triprotic → Releases three protons, for example H₃PO₄

Polyprotic → Release many protons, for example EDTA

it is a weak acid.

In the first equilibrum, it release proton, and the second is released in the second equilibrium. So the first equilibrium will have a Ka1

H₂A  +  H₂O  ⇄  H₃O⁺  +  HA⁻                Ka₁

HA⁻  +  H₂O  ⇄  H₃O⁺  +  A⁻²               Ka₂

The HA⁻ will work as an amphoterous because, it can be a base or an acid, according to this:

HA⁻   +  H₂O  ⇄  H₃O⁺   + A⁻²      Ka₂

HA⁻   +  H₂O  ⇄  OH⁻   + H₂A       Kb₂

Calculate the composition (mass fractions) in the bottom stream.

Answers

Answer:

a) YES ( Basis : F=100kg/h)

b) composition mass fraction in the bottom stream

(Xm)B = 0.25

(Xp)B = 0.1

(Xw)B = 0.65

Explanation:

a)

Can you set a basis of calculation in this problem? Why or why not?

Yes we can set a basis if calculation in this problem.

A good basis makes the calculation more easier. the problem are given in weight  basis so we can choose basis of feed rate of 100kg/h

BASIS : 100kg/h

b)

given that;

mass flow rate of M in the feeds Mf = 0.55*F = 0.55*100 = 55kg/h

mass flow rate of p in the feeds Pf = 0.05*F = 0.05*100 = 5kg/h

mass flow rate of W in the feeds Pf = 0.40*F = 0.40*100 = 40kg/h

Now Balance

F = T + B

( but T=B)

so F = T + T = 2T

B = T = 50kg/h

TOP

mass flow rate of M in the top Mt = 0.85*T = 0.85*50 = 42.5 KG/H

mass flow rate of P in the top Pt = 0kg/h

mass flow rate of W in the top Wt = 0.15*T = 0.15*50 = 7.5kg/h

balance on M

Mf = Mt + Mb

Mb = Mf - Mt = 55kg/h - 42.5kg/h = 12.5kg/h

Balance on P

Pf = Pb + Pt

Pb = Pf - Pt = 5kg/h - 0kg/h = 5kg/h

Balance on W

Wf = Wt + Wb

Wb = Wf - Wt = 40kg/h - 7.5kg/h = 32.5kg/h

So bottom composition

mass fraction of M in Bottom XmB = Mb/B = (12.5kg/g) / (50kg/h) = 0.25

mass fraction of P in Bottom XpB = Pb/B = (5kg/g) / (50kg/h) = 0.1

mass fraction of W in Bottom XwB = Wb/B = (32.5kg/g) / (50kg/h) = 0.65

A solution contains 3.95 g of carbon disulfide (CS2, molar mass = 76.13 g/mol) and 2.43 g of acetone ((CH3)2CO, molar mass = 58.08 g/mol). The vapor pressure of pure carbon disulfide and acetone at 35 oC are 515 torr and 332 torr, respectively. Assuming ideal solution behavior, calculate the vapor pressure of each of the components and the total vapor pressure above the solution. The total vapor pressure above the solution at 35 oC was experimentally determined to be 645 torr. Is the solution ideal? If not, indicate whether the solution deviates from Raoult’s law in a positive or negative manner.

Answers

Answer:

Psol = 433 torr

The solution is not ideal and the solution deviates from Raoult's law in a positive manner

Explanation:

The vapout pressure of a solution can be obtained using Raoult's law:

Psol = P°A* XA + P°B*XB

Where Psol is vapour pressure of solution

P° is vapour pressure of pure substance

X is mole fraction

As we have vapour pressure of pure carbon disulfide and acetone we need to find mole fraction of each compound to solve the vapour pressure of the solution:

Moles carbon disulfide:

3.95g CS₂ * (1mol / 76.13g) = 0.05188 moles

Moles acetone:

2.43g acetone * (1mol / 58.08g) = 0.04184 moles

Mole fraction of CS₂:

0.05188 moles / (0.05188mol + 0.04184mol) =

0.5536

Mole fraction acetone:

1 = X(CS₂) + X(Acetone)

X(Acetone) = 1 - 0.5536 = 0.4464

Solving for vapour pressure of the solution:

Psol = 515torr*0.5536 + 332torr*0.4464

Psol = 433 torr

As the experimental vapor pressure was 645torr > 433 torr (Theoretical vapor pressure), the solution is not ideal and the solution deviates from Raoult's law in a positive manner

Answers

Answer:

The molar mass of the organic solid is 119.9g/mol.

The molecular formula of an organic solid is C4H8O4

Explanation:

Step 1

We find the Molar mass

From the above question, we are given:

A solution of 0.650 g of the solid in 27.8 g of the solvent diphenyl gave a freezing point depression of 1.56 °C. Calculate the molar mass and determine the molecular formula of the solid (kf for diphenyl is 8.00 °C/m)

A freezing point depression = 1.56 °C.

Mass of organic solid= 0.650 g

Mass of diphenyl = 27.8 g

Converting to kilograms

1000g = 1kg

27.8g =

Cross Multiply

= 27.8g × 1 kg/1000g

= 0.0278kg

Boiling point constant = 8.00 °C/m

Molar mass of the organic compound = Boiling point constant × Mass of solid /Freezing point depression × Mass of diphenyl

Molar mass of the organic compound =

8.00 °C/m × 0.650g/1.56°C × 0.0278kg

= 5.2 g°C/m ÷ 0.043368 g°C

= 119.9040767 g/mol

Approximately = 119.9 g/mol

Step 2

Find the Molecular formula

Molecular formula = CxHyOz

Let x = Carbon, y = Hydrogen, z = Oxygen

For x = Carbon

Atomic mass of Carbon = 12.01078

x = % of Carbon in the compound × Molar mass of the organic compound/atomic mass of Carbon

x = 40% × 119.9 g/mol / (12.01078

x = 3.99

x = Approximately = 4

For y = Hydrogen

Atomic mass of Hydrogen = 1.007947

y = % of Hydrogen in the compound × Molar mass of the organic compound/Atomic mass of Hydrogen

x = 6.7% × 119.9 g/mol) / 1. 007947

x = 7.97

x is Approximately = 8

For z = Oxygen

Atomic mass of Oxygen = 15.99943

z = % of Oxygen in the compound × Molar mass of the organic compound/Atomic mass of Oxygen

z = 53.3% × 119.9 g/mol /15.99943

z = 3.99

z is approximately ≈ 4

Therefore,

The molar mass of the organic solid is 119.9 g/mol.

Answers

The SI unit of temperature is the kelvin (K), which spans the same temperature change as the degree Celsius. The Kelvin scale is a thermodynamic scale, meaning that its zero point is at absolute zero rather than the freezing point of water. The second reference point for this scale as it is currently defined is the triple point of water, which is a unique point on the phase diagram of water (a specific combination of pressure and temperature) where ice, liquid water and water vapor are all in equilibrium. The triple point is assigned the temperature of 273.16 K.

The old centigrade scale used the freezing and boiling temperatures of water as its reference points, with one degree centigrade equal to 1/100 of the temperature span between the freezing and boiling points of water. The definition of the Kelvin scale was chosen to make the kelvin the same size as the centigrade degree.

The Celsius scale is defined in terms of the Kelvin scale but is equivalent to the old centigrade scale, which it replaces. It is convenient for reporting weather and cooking temperatures and so on, but is not particularly useful for scientific purposes. For instance, the behavior of gases which approximate ideal gases is such that at zero degrees C they experience a volume change of 1/273 for a one degree change in temperature. This observation provided one of the first indications for the value of absolute zero.

When using the ideal gas law:

PV = nRT

where P is pressure

V is volume

n is the quantity of gas in moles

R is a constant

T is the temperature

it is necessary to use a thermodynamic scale, usually Kelvin.

Another thermodynamic scale, the Rankine scale, has a relationship to the Fahrenheit temperature scale analogous to that between the Kelvin and Celsius scales.

What does 3.5 degree of unsaturation tell you?

Answers

Answer:

It means the chemical entity is a radical

Explanation:

When we talk of unsaturation, we are referring to the number of pi-bonds in a chemical entity. The alkane, alkene and alkyne organic family are used to as common examples to explain the term unsaturation.

While alkynes have 3 bonds, it must be understood that they have 2 pi bonds only and as such their degree of saturation is two.

In the case of an alkene, there is only one single pi bond and as such the degree of unsaturation is 1.

Now in this case, we have a fractional 0.5 degree of unsaturation alongside the 3 to make a total of 3.5. So what’s the issue here?

The fractional part shows that the chemical entity we are dealing with here is a radical. While the integer 3 shows that there are 3 pi-bonds, the half pi bond remaining tells us that there is a missing electron on one of the atoms involved in the chemical bonding and as such, the 1/2 extra degree of unsaturation tends to tell us this.

Kindly recall that a radical is a chemical entity within which we have at the least an unpaired electron.

Which ketone in each pair is more reactive?
a. 2-heptanone or 4-heptanone,
b. bromomethyl phenyl ketone or chloromethyl phenyl ketone

Answers

Answer:

a. 2-heptanone is more reactive than 4-heptanone

b. chloromethyl phenyl ketone is more reactive than bromomethyl phenyl ketone

Explanation:

The reactivity of the carbonyl compound (ketone ) is affected by the steric effect. The steric effect is a hindrance that occurs in the structure or reactivity of a molecule, which is affected by the physical size and the proximity of the adjacent parts of the molecule.

Between 2-heptanone or 4-heptanone, 2-heptanone is more reactive than 4-heptanone. This is because 2-heptanone is less affected by the steric hindrance, unlike the 4-heptanone.

Similarly, the reactivity of the carbonyl compound (ketone) is also affected by the polarity on the carbon compound, which is associated with how electronegative the substituent attached is to the carbonyl compound. From the periodic table, the electronegativity of the Halogen family decreases down the group. Therefore chlorine is more electronegative than bromine.

As such, chloromethyl phenyl ketone is more reactive than bromomethyl phenyl ketone.

This was normally a relaxed meeting at which teachers wearing casual clothes smiled and wished each other well for the summer. But no one was smiling today, because a story in the local newspaper had exploded like a crack of thunder.2 The headline read, Board of Education Plans New Middle School, and the staff members of East Orange Elementary were rattled.3 Principal Tom Drake opined, I am concerned about a situation in which a newspaper already knows school district information that comes as a surprise to me and my teachers. He continued, But of far greater concern is what this means for us, for our colleagues at West Orange, and for students and parents throughout the district.4 Coach Melinda Gardner whispered to her friend, Mr. Dale French, Old Tom is just worried the Board might ask him to retire and make someone else principal of the new campus.5 Mr. French whispered back, Melinda, you be nice now, but he couldnt help smiling at his friends remark.6 As the meeting went on, many teachers worried out loud about what might happen if grades 6-8 from East and 6-8 from West consolidated.7 Ever since the two elementary schools had opened, decades ago, the district had proudly maintained a unique system. While surrounding districts had built new middle schools, Orange kept two elementary buildingsEast and Westwith K-8 graders in each.8 Now, according to the paper, the results of the 2010 census were in. They suggested population growth would soon fill both elementary schools with K-5 students only. Apparently, the Board thought the time was ripe to build one new middle school for 6-8 graders.9Will one campus need two middle school science labs? Dr. Fred Davis, the science department head, asked the group in his usual shy, quiet voice.10Since there is only one middle school library, is the Board going to honor seniority? Mrs. Betty Green asked brashly. Or the Board could just keep whichever librarian has the coolest photos on her social media site, she added sarcastically.11Mrs. Green is worried her lack of computer skills might finally hurt her, Coach Gardner whispered to Mr. French again.12Coach Gardner, please! Principal Drake scolded his gym teacher for whispering. You would not tolerate it if your students were rude. This turn of events has caused real alarm so lets be sensitive to each others concerns.13I apologize for both of us, Tom, Mr. French offered. But lets not get carried away and spoil our summers over this. We dont know if this proposed new campus will actually be built. The census projections could be wrong. Even if they are right, the cost of raising taxes to pay for a new school might not go over well with voters.14 Mr. French continued, I plan to enjoy my summer and expect another great year. Chances are well all have jobs because several teachers retire every year and the Board moves us around to fill the vacancies. Some of us may have new assignments, but well all land somewhere.15 All around the room there were nods of agreement. The atmosphere of gloom gave way to the usual feelings of accomplishment and relief at the end of school.16 Mr. French offered one more uplifting thought. Each spring we graduate our eighth graders and send them on to Central High. If they can adjust to a new building, I think we can too.17 With that, the teachers adjourned and summer vacation began.Write a complete and accurate summary of this text.
