Consider two identical containers, one contains 1.5 moles of nitrogen gas at 250K and the other contains 1.5 moles of nitrogen gas at 350K. Which of the following statements is TRUE? *
0 points

The pressure exerted by the nitrogen gas (N2) is the same in both containers
The average speed of the nitrogen gas (N2) molecules is higher in container #1 than in container #2
The rate at which nitrogen gas (N2) molecules collide with the container walls is lower in container #1 than in container #2
The average kinetic energy of the nitrogen gas (N2) molecules is the same in both containers

Consider Two Identical Containers, One Contains 1.5 Moles Of Nitrogen Gas At 250K And The Other Contains

Answers

Answer 1

We want to see which of the given statements is true for the identical containers with nitrogen gas.

The correct statement is:

"The rate at which nitrogen gas (N2) molecules collide with the container walls is lower in container #1 than in container #2"

Remember the ideal gas equation:

P*V = n*R*T

Where P is the pressure, V is the volume, n is the number of moles, R is a constant, and T is the temperature.

Both gases are in identical containers, so both have the same volume. Also both containers have 1.5 moles of nitrogen, so n is the same number for both containers, and R is a constant, so it is the same for both.

The thing that is different is the temperature, for container 1 we have a temperature of 250K, while for container 2 we have a temperature of 350K, then we can write two pressure equations:

[tex]P_1 = \frac{n*R}{V}*(250k)\\\\P_2 = \frac{n*R}{V}*(350k)[/tex]

Where n*R/V is a constant term.

Then is really clear to see that the pressure exerted by nitrogen will be larger in container 2, because it increases linearly with the temperature and the temperature is larger in container 2.

Also remember that increases in temperature manifest as an increase in the kinetic energy of the molecules of the gas, thus, the container with a larger temperature will have molecules with larger kinetic energy (thus, larger mean velocity)

From the given statements, the only one that is true is:

"The rate at which nitrogen gas (N2) molecules collide with the container walls is lower in container #1 than in container #2"

This collision with the walls is a representation of pressure, this says that container 1 has less pressure than container 2, which is true.

After all the taxes are withheld, Jules's take home pay is about 72% of his total earnings. Estimate his take home pay if his total earnings for the pay period are $240.

Answers

Answer:

172.8

Step-by-step explanation:

72% of 240 is 172.8

You can estimate it by rounding 172.8 to $173

Jules's take $173 for home pay.

What is Percentage?

A relative value indicating hundredth part of any quantity is called percentage.

Given that;

Total earning of Jules's = $240

He take home pay is about 72%.

Now,

Amount for take home pay = 72% of $240

It can be solve as;

72% of $240

72% × 240

72/100 × 240

72/10 × 24

172.8

After estimating we get;

Amount for take home pay = $173

Thus, Jules's take $173 for home pay.

Margie volunteered to supply heart-shaped sugar cookies for her third-grade class' Valentine's Day party. Her mom will use premade cookie dough in a tub and buy pink frosting and sprinkles, too. Margie would like to give one cookie to each of her 26 classmates. One tub of cookie dough makes 20 cookies and costs $9.95. The frosting will cover 30 cookies and costs $4.59. The package of sprinkles covers up to cookies 60 and costs $2.29. When Margie's sister, Nicole, hears about the cookies, she asks her mom if they can bake one cookie for each of the students in her class, too. Nicole is in fifth grade and she has 31 students in her class. How much will the ingredients cost for both of the classes?

Answers

Answer: $41.32

Step-by-step explanation:

1. Figure out how many students need cookies.

26 + 31 = 57, 57 students need cookies, thus they need to make at least 57 cookies.

2. Figure out which ingredients are still needed.

One tub of cookie dough makes 20 cookies, so to make 57 cookies, they will need at least three tubs. One frosting tin covers 30 cookies, so to cover 57 cookies, they will need at least two tins. One bag of sprinkles covers 60 cookies, so they will only need one bag, as 60 > 57.

3. Tally up the prices of each ingredient

Price of cookie dough = 9.95, amount of cookie dough needed = 3

9.95 * 3 = 29.85

Price of frosting = $4.59, amount of frosting needed = 2

4.59 * 2 = 9.18

Price of sprinkles = 2.29, amount of sprinkles needed = 1

2.29 * 1 = 2.29

4. Find the sum.

29.85 + 9.18 + 2.29 = 41.32

90 degree angle is divided into two sides

Answers

Answers:

3x + 40 =64

4x - 6 =26

Step-by-step explanation:

So we are dealing with 2 complementary angles with both add up to 90 degrees. We can write an equation that shows this:

(3x+40) + (4x-6) = 90

Combine like terms

7x + 34 =90

Isolate x

7x = 56

x = 8

Now that we found x, all we have to do is substitute it in the equations:

3x + 40 = ?

3(8) +40 = ?

24+40 = ?

64 = ?

4x - 6 = ?

4(8) - 6 = ?

32 - 6 = ?

26 = ?

Answer:

3x+40= 66

4x-6= 26

Step-by-step explanation:

3x+40+4x-6=90˚ (because the square on the angle represents a 90˚)

Add 4x and 3x

Which is 7x

40 minus 6 is 34

The equation now looks like this:

7x+34=90˚

Subtract 34 on both sides:

7x=56

Divide 7 on both sides:

x=8

For 3x+40

Substitute x with 8

the equation now looks like this:

24+40 Which is 66

For 4x-6

4 times 8 is 32

32 minus 6 which is 26

Subtract 2x from both sides:

6x=24

x = 72°

Step-by-step explanation:

there is a total of 360 degrees in a circle

we know we can add the angle measures shown and set it equal to 360

3x + (x-11) + (2x-61) = 360

combine 'like terms':

6x + (-11) + (-61) = 360

6x + (-72) = 360

6x = 432

x = 72

Check:

[2(72)-61] + (72-11) + 3(72) should equal 360

(144-61) + 61 + 216 = 360

83 + 61 + 216 = 360

360 = 360
