A gas with a volume of 4.0 L at a pressure of 0.9 atm is allowed to expand until the pressure drops to 0.20 atm. What is the new volume?

Answers

Answer: 25

Explanation:

The new volume will be 18 L

What is volume?

The volume of a dry gas of a given mass was inversely proportional to its pressure at constant temperature, according to Boyle's law. At moderate pressures and temperatures, most gases behave like ideal gases.

Calculation of new volume is shown as below:

The new volume of can be calculated by using Boyle's law.

[tex]P_{1} V_{1} = P_{2} V_{2}[/tex]

It is given that, [tex]P_{1}[/tex] = 0.9 atm. [tex]V_{1}[/tex] = 4 L, [tex]P_{2}[/tex] = 0.20 atm

Now, put the values of given data in above equation.

[tex]V_{2}[/tex] = [tex]P_{1}V_{1}[/tex] / [tex]P_{2}[/tex].

[tex]V_{2}[/tex] = (0.9) ×4 / 0.20

= 3.6 / 0.20

= 18 L

therefore, the new volume will be 18 L.

158.5g Zn are produced

Explanation:

To solve this question we have to find the moles of Aluminium. With the moles of Aluminium and the balanced reaction we can find the moles of Zn and its mass as follows:

Moles Al -Molar mass: 26.98g/mol

43.6g Al* (1mol/26.98g) = 1.616 moles Al

Moles Zn:

1.616 moles Al * (3mol Zn / 2mol Al) =

The initial pressure of 0.31 moles of gas in a drum is 742 torr. If gas is added to the drum and the final pressure is 759 torr, how many moles of gas are in the drum? Hint: for this problem, you do not have an equation in the Introduction section, but based on the relationship between pressure and volume, what can you determine about the relationship between pressure and the number of moles?

Answers

Answer:

0.32 mole

Explanation:

From the question given above, the following data were obtained:

Initial mole (n₁) = 0.31 mole

Initial pressure (P₁) = 742 torr

Final pressure (P₂) = 759 torr

Final mole (n₂) =?

The final mole of the gas in the drum can be obtained as follow:

P₁/n₁ = P₂/n₂

742 / 0.31 = 759 / n₂

Cross multiply

742 × n₂ = 0.31 × 759

742 × n₂ = 235.29

Divide both side by 742

n₂ = 235.29 / 742

n₂ = 0.32 mole

Thus, the final mole of the gas in the drum is 0.32 mole

1.
pressure decreases and the temperature decreases
2.
pressure decreases and the temperature increases
3.
pressure increases and the temperature decreases
4.
pressure increases and the temperature increases

Answers

Answer:

The correct option is (3).

Explanation:

The ideal gas equation is given by :

[tex]PV=nRT\\\\V=\dfrac{nRT}{P}[/tex]

The pressure of ideal gas is directly proportional to temperature and inversely proportional to its volume.

We can say that the volume of a 1.00-mole sample of an ideal gas will decrease when the pressure increases and the temperature decreases.

The volume of the idea gas decrease when pressure increases and the temperature decreases. Thus option C is correct.

The ideal gas equation can be given as:

PV = nRT

The equation in terms of pressure and temperature when n=1 can be written as:

Volume = [tex]\rm \dfrac{RT}{P}[/tex]

Accordingly, the volume has been directly proportional to the temperature and has been inversely proportional to the pressure.

Thus, with the decrease in volume, there has been an increase in pressure and a decrease in temperature.

Thus, option C is correct.

How many moles of aluminum oxide will be produced from 0.50 mol of oxygen?

4 Al + 3 O2→ 2 Al2O3

Answers

Answer:

[tex]\boxed {\boxed {\sf \frac {1}{3} \ mol \ Al_2O_3 \approx 0.34 \ mol \ Al_2O_3}}[/tex]

Explanation:

We will use stoichiometry to solve this problem. The reaction given has a formula of

[tex]4Al+3O_2 \rightarrow 2Al_2O_3[/tex]

The coefficients tell us the number of moles necessary for the reaction.

The reaction requires 3 moles of oxygen to produce 2 moles of aluminum oxide. We can make a ratio.

[tex]\frac {3 \ mol \ O_2}{ 2\ mol \ Al_2O_3}}[/tex]

Since we are doing the reaction with 0.5 moles of oxygen, we multiply the ratio by that number.

[tex]0.5 \ mol \ O_2 *\frac {3 \ mol \ O_2}{ 2 \ mol \ Al_2O_3}}[/tex]

Flip the ratio so the moles of oxygen cancel each other out.

[tex]0.5 \ mol \ O_2 *\frac {2 \ mol \ Al_2O_3}{ 3 \ mol \ O_2}}[/tex]

[tex]0.5 *\frac {2 \ mol \ Al_2O_3}{ 3 }[/tex]

[tex]\frac {1 \ mol \ Al_2O_3}{ 3 }[/tex]

[tex]\frac {1}{3} \ mol \ Al_2O_3 = 0.33333 \ mol \ Al_2O_3 \approx 0.34 \ mol \ Al_2O_3[/tex]

0.5 moles of oxygen produces 1/3 or approximately 0.34 moles of aluminum oxide.

Using 1.8x10-5 for the Ka for acetic acid, along with the weight of sodium acetate and volume of acetic acid used to prepare the buffer, calculate the expected pH of the buffer. Show your work for full credit. How well does it compare to the observed value

Answers

Answer:

pH = 4.95

Explanation:

The buffer was created using 4.0082g sodium acetate, mixed with 10.0 mL of 3.0 M acetic acid and 90 mL of deionized water.

Using H-H equation for acetic buffer:

pH = pKa + log [Acetate] / [Acetic acid]

Where pH is the pH of the buffer

pKa = -log Ka = 4.74

[] Are molar concentration of each specie -The volume of the solution is 100mL = 0.1L-:

[Sodium acetate] = 4.0082g * (1mol / 82.03g) = 0.04886 moles / 0.1L

= 0.4886M

[Acetic acid] = 3.0M * (10mL / 100mL) = 0.300M

pH = 4.74 + log [0.4886M] / [0.300M] =

pH = 4.95

How much energy would be released as 95.0 g of acetic acid crystallized?

Answers

Answer:

-18.54kJ of energy would be released

Explanation:

The enthalpy of crystallization is defined as the heat released when 1 mole of a substance change its state from liquid to solid. The ΔHcrystallization of acetic acid is -11.72kJ/mol (ΔHcrystallization = - ΔHfusion).

To solve this question we must convert the mass of acetic acid to moles in order to find the heat released:

Moles acetic acid -Molar mass: 60.052g/mol-:

95.0g * (1mol / 60.052g) = 1.58 moles

A water treatment tablet contains 20.0 mg of tetraglycine hydroperiodide, 40.0% of which is available as soluble iodine. If two tablets are used to treat 1.00 liter of drinking water, what is the concentration in ppm of iodine in the treated water

Answers

Answer:

[tex]16\ \text{ppm}[/tex]

Explanation:

Mass of one tablet = 20 mg

Mass of two tablets = [tex]2\times 20=40\ \text{mg}[/tex]

Percent that is soluble in water = 40%

Mass of tablet that is soluble in water = [tex]0.4\times 40=16\ \text{mg}[/tex]

So, mass of solute is [tex]16\ \text{mg}[/tex]

Density of water = 1 kg/L

Volume of water = 1 L

So, mass of 1 L of water is [tex]1\times 1=1\ \text{kg}=1000\ \text{g}[/tex]

PPM is given by

[tex]\dfrac{\text{Mass of solute}}{\text{Mass of solvent}}\times 10^6=\dfrac{16\times 10^{-3}}{1000}\times 10^6\\ =16\ \text{ppm}[/tex]

Hence, the concentration of iodine in the treated water [tex]16\ \text{ppm}[/tex].
