Answers

Answer:

111 kPa

Explanation:

The new pressure can be found by using the formula for Boyle's law which is

[tex]P_1V_1 = P_2V_2[/tex]

where

P1 is the initial pressure

P2 is the final pressure

V1 is the initial volume

V2 is the final volume

Since we're finding the new pressure

[tex]P_2 = \frac{P_1V_1}{V_2} \\[/tex]

We have

[tex]P_2 = \frac{13 \times 197000}{23} = \frac{2561000}{23} \\ = 111347.826...[/tex]

We have the final answer as

111 kPa

A container has a volume of 5.85 L and a pressure of 4.25 atm. What will the volume be
If the containers pressure is changed to 2.75 atm?

Answer:

9.04 L

Explanation:

The new volume can be found by using the formula for Boyle's law which is

[tex]P_1V_1 = P_2V_2[/tex]

Since we're finding the new volume

[tex]V_2 = \frac{P_1V_1}{P_2} \\[/tex]

We have

When the pressure is in a certain gas cylinder with a volume of 4.50 L reaches 500atm, the cylinder is likely to explode. If this cylinder contains 40.0 moles of argon at 25.0°C, is it on the verge of exploding? Calculate the pressure

Answers

Answer:

The cylinder is nit on the verge of exploding.

Explanation:

Temperature= 25.0°C

The conversion of T(°C) to T(K) is shown below:

T(K) = T(°C)+ 273.15

So,

T=(25.0 + 273.15) K = 298.15 K

Volume= 4.50 L

Moles= 40.0 mol

Using ideal gas equation as:

PV = nRT

where,

P is the pressure

V is the volume

n is the number of moles

T is the temperature

R is gas constant having value = 0.0821 Latm/ K. mol x 298.15 K

⇔ P= 217.58 atm

Pressure limit = 500 atm .

if the hydrogen ion concentration [H+] in a solution is 1.87 x 10^-11M what is the [OH-]

Answers

By using pH formula, the concentration of hydroxyl ion [OH-] will be 5.3 ×[tex]10^{-4}[/tex] M.

What is pH?

The pH scale is a measurement of hydrogen ion concentration that is used to determine the acidity as well as alkalinity of a solution.

Calculation of [OH-] by using formula of pH.

Given data:

[H+] = 1.87 x [tex]10^{-11} M[/tex]

[OH-] = ?

Calculation of [OH-] is shown below:

It can be calculated by using the formula:

pH = -log [H+]

Put the value of concentration of hydrogen ion [H+] in above formula.

pH = -log (1.87 x [tex]10^{-11} M[/tex])

pH = -log (1.87) -log ( [tex]10^{-11} M[/tex])

pH = -0.27 +11

pH = 10.73

Now, use the formula, pH +pOH = 14

pOH = 14 - pH

pOH = 14 - 10.73

pOH = 3.27

Now, use formula pOH = -log [OH-]

[OH-] = [tex]10^{-pOH}[/tex]

[OH-] = [tex]10^{-3.27}[/tex]

[OH-] = 5.3 ×[tex]10^{-4}[/tex] M

Therefore, the concentration of hydroxyl ion [OH-] will be 5.3 ×[tex]10^{-4}[/tex] M.

Which property is NOT used to separate a mixture?

Conductivity.

Explanation:

plssss show your work will mark the brainliest

Answers

Answer:

135.16 mL

Explanation:

From the question,

Applying,

PV/T = P'V'/T'.................... Equation 1

Where P = Initial pressure of the gas, V = Initial volume of the gas, T = Initial Temperature of the gas in Kelvin, P' = Final pressure of the gas, V' = Final Volume of the gas, T' = Final temperature of the gas in Kelvin.

Make V' the subject of the equation

V' = PVT'/TP'................... Equation 2

Given: P = 600 torr, V = 115 mL, T = 50 °C = (50+273) K = 323 K, T' = 75 °C = (75+273) K = 348 K, P' = 550 torr

Substitute these values into equation 2

V' = (600×115×348)/(323×550)

V' = 24012000/117650

V' = 135.16 mL
