A student reads a barometer in the laboratory and finds the prevailing atmospheric pressure to be 739 mmHg. Express this pressure in torr and in atmospheres. Hint: Pressure

Answers

Answer 1

Answer:

[tex]739\,mm\,Hg = 739\,torr = 0.972\,atm[/tex]

Explanation:

760 torr equals 760 mm Hg and 1 atmosphere of pressure. Hence, we get all equivalencies by simple rule of three:

[tex]x = 739\,mm\,Hg\times \frac{760\,torr}{760\,mm\,Hg}[/tex]

[tex]x = 739\,torr[/tex]

[tex]x = 739\,mm\,Hg\times \frac{1\,atm}{760\,mm\,Hg}[/tex]

[tex]x = 0.972\,atm[/tex]

When pumping air into a tire, you have to pull back on the pump plunger to fill the pump with air. This increases the volume of the air inside the pump. This increase in volume has what effect on the gases inside the pump?

Question 9 options:

the gas molecules inside the pump are able to spread out more which decreases the pressure of the gas.


the gas molecules inside the pump get compressed and packed closer together which decreases the pressure of the gas.


the gas molecules inside the pump are able to spread out more which increases the pressure of the gas.


the gas molecules inside the pump get compressed and packed closer together which increases the pressure of the gas.

Answers

Answer:

Pulling back on the plunger allows you to put in more air into the pump and the more air you have inside a fixed volume, the greater the pressure becomes. (D)

Visible light is a section of spectrum of different wavelengths. The shorter the wavelength, the higher energy, so the more refraction. Different wavelengths refract at different angles, causing the formation of rainbows.

The power of the crane was 68600 W
Caculate the time taken for the crane to do 3430000 J of work
Give the unit

Answers

Answer:

t = 50 s

Explanation:

P = W/t

Solving for t,

t = W/P = (3430000 J)/(68600 Watts)

= 50 s

Note: 1 Watt = 1 J/s

According to the question, the time that is taken by the crane which has the power of 68600 W to 3430000 J of work is 50 seconds.

What is Power?

Power may be defined as the amount of energy that is significantly transmitted or converted per unit of time. In a more simple sense, it is also characterized as the measure of the rate of doing work.

According to the question,

The power of the crane = 68600 W.

The amount of work that the crane has to do = 3430000 J.

Time may be calculated with the help of the following formula:

Power = Work/time.Time = Work/power = 3430000 J/68600 W = 50 seconds. (where 1 W = 1 J/sec).

Therefore, according to the question, the time that is taken by the crane which has the power of 68600 W to 3430000 J of work is 50 seconds.

Which is NOT true of the Sc3+ ion?

Multiple choice question.

A)
It is a scandium ion with three positive charges.

B)
It was formed by the loss of 4s and 3d electrons.

C)
It has the same electron configuration as Ar.

D)
It is considered to be a different element than a neutral Sc atom.

Answers

Answer:

D. It is considered to be a different element than a neutral Sc atom.

The statement i.e. not true of the Sc3+ ion is that it is considered to be a different element than a neutral Sc atom.

The statements that should be considered as true regarding the Sc3 + ion is as follows:

It represents the scandium ion having 3 positive charges.It is created via the loss of 4s & 3d electrons. And, it contains the similar configuration as treated as Ar.

Therefore we can conclude that the statement i.e. not true of the Sc3+ ion is that it is considered to be a different element than a neutral Sc atom.

Calculate the moles of of Fe that would be needed to form 336 grams of Cl2 (round your answer to 2 decimals)

2Fe + 3Cl2 → 2FeCl3

Answers

Answer:

6.32 moles of Fe

Explanation:

The given chemical equation is presented as follows;

2Fe + 3Cl₂ → 2FeCl₃

The mass of Cl₂ in the reaction = 336 grams

The molar mass of chlorine gas Cl₂ = 35.435 g/mol

The number of moles, n = Mass/(Molar mass)

The number of moles of Cl₂ in the reaction, n = 336 g/(35.435 g/mol) ≈ 9.842 moles

From the given reaction, 3 moles of Cl₂ react with 2 moles of Fe to produce 2 moles of FeCl₃

By the law of definite proportions, we have that 9.482 moles of Cl₂ will react with approximately 9.482 × 2/3 = 6.32 moles of Fe to produce approximately 6.32 moles of FeCl₃

Therefore, approximately 6.32 moles of Fe will be required to react with 336 grams of Cl₂.

Explanation:

on an isobaric process, an increase on the volume implies an increase on the temperature:

V1/T1 = V2/T2

T2 = V2T1/V1 = 15.0 L×150 K/3.00 L = 750 K

t/ºC = T/K - 273 = 750 K/K - 273

t = 477 ºC
