If the pressure of a 2.00 L sample of gas is 50.0 kPa, what pressure does the gas exert if its volume is decreased to 20.0 mL?

Which equation should you use?

Answers

Answer:

__________________________________________________________

Which equation should you use?

B. P₁V₁=P₂V₂

What is the new pressure?  

✔ 5000  kPa

__________________________________________________________

Explanation:

The problem gives initial volume (2.00 L), final volume (20.0 mL), and initial pressure (50.0 kPa). Then it asks to find the final pressure. Answer B has all these variables, with P₁=initial pressure, P₂=final pressure, V₁=initial volume, and V₂=final volume. Plug the given values into the equation and then solve for the unknown value, which is P₂, final pressure.

When plugging in the values, use consistent units. 2L=2000 mL, I chose to make the consistent unit in mL. You'll get the same answer if you choose to use L as the consistent unit.

[tex]2000*50=20*P2[/tex]

[tex]100000=20*P2[/tex]

Divide both sides by 20

[tex]100000/20=(20*P2)/20[/tex]

[tex]5000=P2[/tex]

Find the area of the sector with a central angel of 120 and a radius of 8 inshces. Leave in terms of pie

Answers

Answer:

A = 66.98 square in.

Explanation:

The Area of a sector is given by the formula

[tex]A = \frac{\theta}{360}\times \pi r^2[/tex]

here θ is the central angle and r is the radius

given that θ = 120° and radius =  8 inches

[tex]A = \frac{120}{360}\times3.14\times 8^2[/tex]

A = 66.98 square in.

Determine the volume of a helium balloon given the balloon was filled from a container 0.15L of gas at 2 atm if the new pressure is 0.97 atm. Assume constant temperature.

Answers

Answer:

The volume of the helium balloon is 0.306 L.

Explanation:

Boyle's law states that the volume occupied by a given gaseous mass at constant temperature is inversely proportional to pressure. That is, if the pressure increases, the volume decreases, while if the pressure decreases, the volume increases.

Mathematically, Boyle's law indicates that the product of pressure and volume always has the same value:

P*V= k

Assuming that you have a certain volume of gas V1 that is at a pressure P1 at the beginning, by varying the volume of gas to a new value V2, then the pressure will change to P2, and it will be fulfilled:

P1*V1= P2*V2

In this case:

P1= 2 atmV1= 0.15 LP2= 0.97 atmV2= ?

Replacing:

2 atm* 0.15 L= 0.97 atm* V2

Solving:

[tex]V2= \frac{2 atm* 0.15 L}{0.97 atm}[/tex]

V2= 0.306 L

The volume of the helium balloon is 0.306 L.

How would the balloons interaction with each other change if the balloons were moved further apart? Explain.

Answers

Explanation:

It is known that like charges repel each other and unlike charges attract each other.

As the balloons are facing each other with like charges so they will repel each other. Hence, they will move apart.

But when balloons were moved further apart then interaction between them will decrease and then there will be no force of repulsion or force of attraction.

A test light with an electrical resistance of 9.00 S2 draws a current of 1.50 A when
it is connected to an electrical source. How much power does the light use?

Answers

Answer:

20.25 W

Explanation:

Applying,

P = I²R.................... Equation 1

Where P = Power, I = current drawn by the test light, R = Resistance of the test light

From the question,

Given: I = 1.5 A, R = 9.00 Ω

Substitute these values into equation 1

P = (1.5²)(9)

P = 2.25×9

P = 20.25 W

Finally, "we leave it as an exercise for the student" to calculate that

b. Identify the limiting reactant

The limiting reactant is the amount of chocolate chips because they can produce the smallest amount of cookies.

c. Determine the theoretical yield

The theoretical yield is 54 cookies, because that is all you can get from the chocolate chips provided.

The percent yield obtained on baking the cookies is 20 % and the theoretical yield is 25 cookies.

What is percent yield?

Percent yield is defined as the ratio of actual yield to the theoretical yield multiplied by 100. If the actual and theoretical yield are same then the percent yield is 100%.If actual yield is less than the theoretical yield then the percent yield is less than 100%.Reason of this condition arising is the incompletion of reaction or loss of sample during recovery process.

In cases where percent yield is over 100% it indicates that more sample is recovered than the predicted amount.This condition arises when there are other simultaneous reactions taking place leading to the formation of product. It can also arise if there is incomplete removal of impurities from the sample .

As cookies obtained is 5 it is observed yield while 25 is theoretical yield so the percent yield, 5/25×100=20%.

Which atom attracts electrons most strongly? br F Rb

Answers

Flourine because it has less energy levels hence strong nuclear force of attraction

Fluorine has the highest electronegativity in comparison to other elements therefore, the F atom attracts electrons most strongly.

What is electronegativity?

The electronegativity of an atom measures the tendency of an element to attract the bonded electrons pairs towards itself. The electronegativity of an atom is determined with respect to another bonded atom.

Electronegativity can be described as a chemical property of an atom or a functional group to attract electrons toward itself. The electronegativity of an atom depends on the atomic number and the distance of valence electrons from the charged nuclei.

When two different atoms are bonded through a bond. More electronegative will attract the electron density of the bond towards itself.

As we know, the electronegativity decreases as we move down the group in the periodic table. Fluorine is the most electronegative element in the periodic table therefore, Fluorine (F) will attract the electrons toward it most strongly.

b. 3.022 x 1023 molecules S,

c. 4.302 x 10 molecules S

d. 8.203 x 10' molecules S2

Answers

Answer: There are [tex]2.032 \times 10^{25}[/tex] molecules [tex]S_{2}[/tex] gas are in 756.2 L.

Explanation:

It is known that 1 mole of any gas equals 22.4 L at STP. Hence, number of  moles present in 756.2 L are calculated as follows.

[tex]Mole = \frac{Volume}{22.4 L}\\= \frac{756.2 L}{22.4 L}\\= 33.76 mol[/tex]

According to mole concept, 1 mole of every substance contains [tex]6.022 \times 10^{23}[/tex] molecules.

Therefore, molecules of S present in 33.76 moles are calculated as follows.

[tex]1 mol = 6.022 \times 10^{23}\\33.76 mol = 33.76 \times 6.022 \times 10^{23}\\= 2.032 \times 10^{25}[/tex]

Thus, we can conclude that there are [tex]2.032 \times 10^{25}[/tex] molecules [tex]S_{2}[/tex] gas are in 756.2 L.

How many moles of H2O
moles of H2O are needed to produce 55.7 moles of H2?

Answers

Answer: 55.7 moles of [tex]H_2O[/tex] are needed to produce the given amount of [tex]H_2[/tex]

Explanation:

The number of moles is defined as the ratio of the mass of a substance to its molar mass.

The equation used is:

[tex]\text{Number of moles}=\frac{\text{Given mass}}{\text{Molar mass}}[/tex] ......(1)

Given values:

Moles of [tex]H_2[/tex] = 55.7 moles

The chemical equation for the decomposition of water follows:

[tex]2H_2O\rightarrow 2H_2+O_2[/tex]

By the stoichiometry of the reaction:

If 2 moles of hydrogen gas is produced from 2 moles of water

So, 55.7 moles of hydrogen gas will be produced by = [tex]\frac{2}{2}\times 55.7=55.7mol[/tex] of water

Hence, 55.7 moles of [tex]H_2O[/tex] are needed to produce the given amount of [tex]H_2[/tex]

Taking into account the reaction stoichiometry,

Reaction stoichiometry

In first place, the balanced reaction is:

2 H₂O → 2 H₂ + O₂

By reaction stoichiometry (that is, the relationship between the amount of reagents and products in a chemical reaction), the following amounts of moles of each compound participate in the reaction:

H₂O: 2 molesH₂: 2 molesO₂: 1 mole

Moles of H₂O required

The following rule of three can be applied: if by reaction stoichiometry 2 moles of H₂ are produced from 2 moles of H₂O, 55.7 moles of H₂ are produced from how many moles of H₂O?

[tex]moles of H_{2} O=\frac{55.7 moles of H_{2}x 2 moles of H_{2} O}{2 moles of H_{2}}[/tex]

moles of H₂O= 55.7 moles

Finally, 55.7 moles of H₂O is requiredto produce 55.7 moles of H₂.

If the half life of iridium-182 is 15 years, how much of a 3 gram sample is left after 2 half-lives?
A) .57 grams
B) .70 grams
C) 2.25 grams
D) .75 grams

Answers

Answer:

D. 0.75 grams

Explanation:

The data given on the iridium 182 are;

The half life of the iridium 182, [tex]t_{(1/2)}[/tex] = 15 years

The mass of the sample of iridium, N₀ = 3 grams

The amount left, N(t) after two half lives is given as follows;

[tex]N(t) = N_0 \left (\dfrac{1}{2} \right )^{\dfrac{t}{t_{1/2}} }[/tex]

For two half lives, t = 2 × [tex]t_{(1/2)}[/tex]

∴ t = 2 × 15 = 30

[tex]\dfrac{t}{t_{(1/2)}} = \dfrac{30}{15} = 2[/tex]
