Calculate the work for the expansion of CO2 from 1.0 to 6.5 litres against pressure of 1.0 atm at constant temperature

Answers

Answer 1

Answer:

557.3J is the work of expansion of the CO2 gas

Explanation:

The work of expansion of a gas under constant temperature and pressure (Isobaric pressure) is:

W = P*ΔV

Where W is work

P is pressure = 1.0atm

ΔV = Final volume - Initial Volume = 6.5L - 1.0L = 5.5L

Replacing:

W = 1.0atm*5.5L

W = 5.5atmL

In Joules (1atmL = 101.325J):

5.5atmL * (101.325J / 1atmL) =

557.3J is the work of expansion of the CO2 gas

C. They would both be the same temperature.
D. There is not enough information

Answers

Answer:

A. The 100 mL of water would be a higher temperature than the 1,000 mL of water.

Explanation:

Since the volume of water affects temperature, when the volume increases this results in a lower temperature. This means that the water with the smaller volume will have a higher temperature.

Define what natural gas is, explain how it forms, and
what it is used for today.

Answers

Answer:

is a naturally occurring hydrocarbon gas mixture consisting primarily of methane, but commonly including varying amounts of other higher alkanes, and sometimes a small percentage of carbon dioxide, nitrogen, hydrogen sulfide, or helium.

It is formed when layers of decomposing plant and animal matter are exposed to intense heat and pressure under the surface of the Earth over millions of years. The energy that the plants originally obtained from the sun is stored in the form of chemical bonds in the gas

for heating, cooking, and electricity generation. It is also used as a fuel for vehicles and as a chemical feedstock in the manufacture of plastics and other commercially important organic chemicals.

what is molarity ? also write its formula ?​

Answers

Answer:

Definition:

Molarity of a given solution is defined as the total number of moles of solute per litre of solution. The molality of a solution is dependent on the changes in physical properties of the system such as pressure and temperature as unlike mass, the volume of the system changes with the change in physical conditions of the system. Molarity is represented by M, which is termed as molar. One molar is the molarity of a solution where one gram of solute is dissolved in a litre of solution. As we know, in a solution, the solvent and solute blend to form a solution, hence, the total volume of the solution is taken.

Formula :

[tex]m \: = \frac{n}{v} [/tex]

Where,

m = molar concentration

n = moles of solute

How many grams of solid iron will be produced from 32.1 grams of iron (III) oxide? Hint: Balance the equation first

Answers

Answer:

22.45g of Fe will be produced

Explanation:

The balanced reaction is:

Fe₂O₃(s) + 3CO(g) → 2Fe(s) + 3CO₂(g)

Where 1 mole of Iron (III) oxide reacts with 2 moles of Iron

To solve this question we have to find the moles of iron (III) oxide. With these moles and the balanced reaction we can find the moles of iron produced and its mass:

Moles iron (III) oxide -Molar mass: 159.69g/mol-

32.1g Fe₂O₃ * (1mol / 159.69g) = 0.201 moles Fe₂O₃

Moles Iron:

0.201 moles Fe₂O₃ * (2mol Fe / 1mol Fe₂O₃) = 0.402 moles of Fe

Mass Fe -Molar mass: 55.845g/mol-

0.402 moles of Fe * (55.845g/mol) =

22.45g of Fe will be produced

6. Find the number of molecules in 33.6 L of co, at STP? What is the name
of this compound?
!!!!!!PLEASE HELP!!!!!!!!!!

Answers

Question 6 says CO2, not CO.

At STP, one mole of any gas occupies 22.4 L. So, at STP, 33.6 L of our gas contains (33.6 L)/(22.4 L/mol) = 1.5 moles.

One mole of any substance contains 6.022 × 10²³ particles, or in this case, molecules. So 1.5 moles contains (1.5 moles)(6.022 × 10²³ molecules/mole) = 9.03 × 10²³ molecules.

As you can see, in this case it doesn’t matter what the identity of the gas is. But it does matter when it comes to naming. If the substance is CO, as you’ve typed, its name is carbon monoxide. If the substance is CO2 as it’s presented in the image, then its name is carbon dioxide.

How many grams of NaOH are produced from 2.1g of Na2O?
Na2O + H20 --> 2NaOH

Answers

Answer:

2.72g

Explanation:

The balanced equation of this reaction is given as follows:

Na2O + H20 --> 2NaOH

Based on this balanced equation, 1 mole of Na2O will produce 2 moles of NaOH.

First, we need to convert mass of Na2O into moles by using the formula;

mole = mass/molar mass

Molar mass of Na2O = 23(2) + 16

= 46 + 16

= 62g/mol

mole = 2.1g/62g/mol

mole of Na2O = 0.034mol

Hence, if 1 mole of Na2O will produce 2 moles of NaOH.

Then, 0.034mol of Na2O will produce (0.034 × 2) = 0.068mol of NaOH.

To convert mole of NaOH to mass, we use;

mole = mass/molar mass

Molar mass of NaOH = 23 + 16 + 1 = 40g/mol

0.068 = mass/40

mass of NaOH produced = 2.72g.

What is the empirical formula for a compound that has 1.5 moles of copper and 0.5 moles of phosphorus?

Answers

Answer:

[tex]Cu_{3}P[/tex]

Explanation:

usually, the first step is to calculate the moles but since that is already given in the question we can move onto the next step

least molar ratio:

Cu =  [tex]\frac{1.5}{0.5}[/tex] = 3

P = [tex]\frac{0.5}{0.5}[/tex] = 1

thus, empirical formula = [tex]Cu_{3}P[/tex]

The empirical formula for a compound that has 1.5 moles of copper and 0.5 moles of phosphorus is Cu₃P.

What is the empirical formula?

Empirical formula of any compound gives idea about the number of constituents particles present in that compound by mentioning the ration.

In the question, given that:

Moles of copper = 1.5 moles

Moles of phophorous = 0.5 moles

Now we divide the given moles by the smallest number to get the ration number as follow:
Cu  :  P

1.5/0.5  :  0.5/0.5

3  :  1

Hence, required empirical formula is Cu₃P.

A car with a mass of 3,500lbs accelerates negatively from 35m/s to 8m/s in 8s. What is the
car's negative acceleration?

Answers

Answer:

[tex]a=-3.37\ m/s^2[/tex]

Explanation:

Given that,

A car accelerates negatively from 35m/s to 8m/s in 8s.

We need to find the car's acceleration.

Initial speed, u = 35 m/s

Final speed, v = 8 m/s

Time, t = 8 s

The acceleration of an object is equal to the rate of change of velocity. So,

[tex]a=\dfrac{v-u}{t}[/tex]

Put all the values,

[tex]a=\dfrac{8-35}{8}\\\\a=-3.37\ m/s^2[/tex]

So, the acceleration of the car is equal to [tex]-3.37\ m/s^2[/tex].

A pool float was filled with air to capacity in the middle of a hot day. The next morning the pool float looked different yet no gas escaped or entered the float. Describe what you think the float looked like in the morning and why it occurred.

Answers

Answer:

The pool float looked would have looked deflated the next morning.

Explanation:

When temperature decreases the volume decreases

Answer:

The pool float most likely looked a little deflated or pushed in

Explanation:

The pool float most likely looked a little deflated or pushed in. This is because during the night temperatures most likely dropped. These cold temperatures during the night would have caused the air molecules inside the pool float to come closer together which would cause there to be more excess space inside the pool float. Therefore, allowing it to collapse into itself. This would be far worse if the float was filled with helium or another gas other than O2.
