A gas occupies a volume of 500. Milliliters at a pressure of 38.0 kPa and a temperature of 298 K. At what temperature will the gas occupy a volume of 250. Milliliters and have a pressure of 76.0 kPa?

Answers

Answer 1

Answer:

A gas occupies a volume of 250 mL at a pressure of 76 kPa and a temperature of 298 K.

Explanation:

Charles's law states that for a given sum of gas at constant pressure, as the temperature increases, the volume of the gas increases and as the temperature decreases, the volume of the gas decreases. This mathematical law expresses that the quotient that exists between the volume and the temperature will always have the same value:

[tex]\frac{V}{T} =k[/tex]

Gay-Lussac's law says that when there is a constant volume, as the temperature increases, the pressure of the gas increases. And when the temperature is decreased, the pressure of the gas decreases. This law mathematically says that the quotient between pressure and temperature is constant:

[tex]\frac{P}{T} =k[/tex]

Finally, Boyle's law says that the volume occupied by a certain gaseous mass at constant temperature is inversely proportional to the pressure. This law is expressed mathematically as

P * V = k

Combined law equation is the combination of three gas laws called Boyle's, Charlie's and Gay-Lusac's law:

[tex]\frac{P*V}{T} =k[/tex]

Analyzing an initial state 1 and a final state 2, it is satisfied:

[tex]\frac{P1*V1}{T1} =\frac{P2*V2}{T2}[/tex]

In this case:

P1= 38 kPaV1= 500 mLT1= 298 KP2= 76 kPaV2= 250 mLT2= ?

Replacing:

[tex]\frac{38 kPa*500 mL}{298 K} =\frac{76 kPa*250 mL}{T2}[/tex]

Solving:

[tex]T2*\frac{38 kPa*500 mL}{298 K} =76 kPa*250 mL[/tex]

[tex]T2=\frac{76 kPa*250 mL*298 K}{38 kPa*500 mL}[/tex]

T2= 298 K

A gas occupies a volume of 250 mL at a pressure of 76 kPa and a temperature of 298 K.

What is the purpose of a buffer?

Answers

The main purpose of a buffer solution is just to resist the change in pH so that the pH of the solution won't be much affected when we add an acid or base into it. The added acid or base is neutralized.

Answer: A buffer solution is a solution made to prevent the pH level of something from changing when you add a base or an acid to it. For example, if you put a buffer solution in a pool, and then you put chlorine in it, the chlorine's effect on the PH level will be suppressed.

What is the amount of moles of NaOH, if the solution molarity is .33 M NaOH in 0.75 L solution

Answers

Answer:

The amount of moles of NaOH is 0.0495

Explanation:

Molarity is a measure of concentration that is defined as the number of moles of solute that are dissolved in a given volume.

In symbolic form molarity  is presented as:

[tex]Molarity=\frac{number of moles of solute}{volume}[/tex]

Molarity is expressed in units [tex]\frac{moles}{liter}[/tex].

In this case:

Molarity= 0.33 MNumber of moles of solute= ?Volume= 0.75 L

Replacing in the definition of molarity:

[tex]0.33 M=\frac{number of moles of solute}{0.75 L}[/tex]

number of moles of solute= 0.33 M* 0.75 L

number of moles of solute= 0.0495 moles

The amount of moles of NaOH is 0.0495

Answer:

0.248 moles of NaOH

Explanation:

Concept of Molarity is mol/L

[x] = 1 M

1 mol of x contained in 1 L of solution. We write molar concentrations between []

M = mol/L then M . L = mol

Our solution is NaOH

0.33 M . 0.75L = mol

This solution contains 0.248 moles of NaOH

Explanation:

The excessive pumping of water through well is the major reason for the drop of ground water level. The nearby farms over use water and pumps from undergrounds.

What is underground water?

Water beneath the earth surface is called ground water. The storage of ground water is a very important in all areas to sustain our need for water and it must be maintained pure without the presence of overdose of heavy metals and other impurities.

Reduction in the level of ground water storage is a serious issue that might leads to a scenario where the drinking water is not sufficient. The uncontrolled use of pump water by factories,  industries and farms results in the drop of ground water level.

The nearby farms might pumping water from sources uncontrollably in the area. That is the main reason of dropping in ground water level. Hence, option B is correct.

L•atm/mol · °C
mL • atm/mol. K
L• kPa/mol - K

Answers

Answer:

A. L•atm/mol K

Explanation:

The ideal gas law equation is given as follows:

PV = nRT

Where;

P = pressure (atm)

V = volume (L)

n = number of moles (mol)

R = gas law constant

T = temperature (K)

As rightly stated in this question, R is the ideal gas constant, which can be different depending on the unit of the other components.

At STP;

V = 22.4L

P = 1 atm

T = 273 K

n = 1 mole

Hence, using PV = nRT

R = PV/nT

R = 1 × 22.4/1 × 273

R = 22.4/273

R = 0.08205

Approximately, R = 0.0821

With the units of P as atm, V as L, n as mol and T as K; R will be 0.0821 L•atm/mol K

If I add 25 mL of water to 125 mL of a 0.15 M NaOH solution, what will the molarity of the diluted solution be? (convert mL to L and round answer to 3 decimals)

Answers

Answer:

0.75 M

Explanation:

M1 = 0.15 M

V1 = 125 mL or 0.125 L

M2 = Y

V2 = 25 mL or 0.025 L

0.15 M x 0.125 mL = Y x 0.025 L

Y =  0.15 M x 0.125 mL / 0.025 L

Cancel out the mL

Y = 0.01875M /  0.025 L

Y = 0.75M

Answer:

0.125 M

Explanation:

M₁V₁ = M₂V₂

125 mL / 1000 = 0.125 L = V₁

25 + 125 = 150 mL / 1000 = 0.150 L = V₂

0.15 M = M₁

M₁ × V₁ / V₂ = M₂

(0.15) × (0.125) / (0.150) = 0.125 M

0.125 M is the answer

A sample of sulfur dioxide occupies a volume of 6052 mL at 352 K and 892 mm Hg. What volume will the sulfur dioxide occupy at STP?

Answers

Answer:

5511.99 mL

Explanation:

Given data

Volume V1= 6052 mL

Temperature T1= 352K

Pressure P1= 892 mm Hg

At STP the parameters of  gas are

Temperature T2= 273.15 K

Pressure P2= 760 mmHg

Applying  the gas equation

P1V1/T1= P2V2/T2

Substitute to find V2 we have

892*6052/352= 760*V2/273.15

5398384/352= 760*V2/273.15

15336.31= 760*V2/273.15

Cross multiply

15336.31*273.15=  760*V2

4189113.0765=  760*V2

4189113.0765/760= V2

V2= 5511.99 mL

Hence the volume at STP is 5511.99 mL

Calculate the freezing point of a nonionizing antifreeze solution containing 388 g ethylene glycol, C2H6O2, and 510 g of water.

Answers

Answer:

T° freezing solution = -22.8°C

Explanation:

To solve this problem we apply, the Freezing Point Depression. This is a colligative property which its formula is:

T° freezing pure solvent - T° freezing solution = Kf . molality . i

i = Van't Hoff factor.

We have been informed is a nonionizing solute, so i = 1

Our solute is ethylene glycol, so le'ts determine the moles to get molality

388 g . 1 mol / 62.07 g = 6.25 moles

molality (m) = moles of solute /kg of solvent

We convert mass of solvent, water, to kg → 510 g . 1kg /1000g = 0.510 kg

6.25 mol /0.510kg = 12.25 m

We replace at formula → 0°C - T° freezing solution = 1.86°C/m . 12.25 m . 1

T° freezing solution = -22.8°C

Answers

Answer: The number of molecules in a 45.6 gram sample of [tex]C_{2}H_{4}[/tex] are [tex]9.78 \times 10^{23}[/tex].

Explanation:

Given: Mass of [tex]C_{2}H_{4}[/tex] = 45.6 g

Molar mass of [tex]C_{2}H_{4}[/tex] is 28.05 g/mol.

Therefore, number of moles of [tex]C_{2}H_{4}[/tex] are calculated as follows.

[tex]No. of moles = \frac{mass}{molarmass}\\= \frac{45.6 g}{28.05 g/mol}\\= 1.62 mol[/tex]

According to the mole concept, 1 mole of every substance contains [tex]6.022 \times 10^{23}[/tex] molecules. Hence, number of molecules present in 1.62 mol are calculated as follows.

[tex]1.62 \times 6.022 \times 10^{23}\\= 9.78 \times 10^{23}[/tex]

Thus, we can conclude that the number of molecules in a 45.6 gram sample of [tex]C_{2}H_{4}[/tex] are [tex]9.78 \times 10^{23}[/tex].

Which statement about the linear factors and zeros of a quadratic function is alwaystrue?A. The constants of the linear factors are the opposite of the function's zeros.B. A function's zeros can be determined by setting each linear factor equal to 0 andsolving.C. If a function's zero is an integer, then the coefficient of the variable in the linear factormust be one.D. Multiplying the constants of the linear factors gives one of the function's zeros, andadding the constants gives the other zero.
