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 LExplanation:
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
[tex]V_2 = \frac{4.25 \times 5.85}{2.75} = \frac{24.8625}{2.75} \\ = 9.0409...[/tex]
We have the final answer as
9.04 LHope this helps you

[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

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

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

How many liters of ammonia gas can be formed from 24.5 L of hydrogen gas at STP?
Answer: 16.3 L of ammonia gas can be formed from 24.5 L of hydrogen gas at STP
Explanation:
According to avogadro's law, 1 mole of every substance occupies 22.4 L at STP and contains avogadro's number [tex]6.023\times 10^{23}[/tex] of particles.
The balanced chemical equation is:
[tex]3H_2+N_2\rightarrow 2NH_3[/tex]
According to stoichiometry :
[tex]3\times 22.4=67.2L[/tex] of [tex]H_2[/tex] produce = [tex]2\times 22.4=44.8L[/tex] of [tex]NH_3[/tex] at STP
Thus 24.5 L of [tex]H_2[/tex] will produce= [tex]\frac{44.8}{67.2}\times 24.5=16.3L[/tex] of [tex]NH_3[/tex] at STP
Thus 16.3 L of ammonia gas can be formed from 24.5 L of hydrogen gas at STP
Which property is NOT used to separate a mixture?
Answer:
Conductivity.
Explanation:
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
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 .
