The absolute temperature of a fixed mass of ideal gas is tripled while its volume remains constant. The ratio of the final pressure of the gas to its initial pressure is

Answers

Answer 1

Answer:

3 : 1

Explanation:

The following data were obtained from the question:

Initial temperature (T₁) = T

Initial pressure (P₁) = P

Final temperature (T₂) = 3T

Final pressure (P₂) =..?

Since the volume is constant, we shall use the following formula P₁ /T₁ = P₂ /T₂ to obtain the final pressure. This is illustrated below:

P₁ /T₁ = P₂ /T₂

P/T = P₂ /3T

Cross multiply

T × P₂ = P × 3T

Divide both side by T

P₂ = P × 3T /T

P₂ = P × 3

P₂ = 3P

Therefore, the final pressure is tripled.

Finally, we shall determine the ratio of the final pressure to the initial pressure as follow:

Initial pressure (P₁) = P

Final pressure (P₂) = 3P

Final pressure (P₂) : Initial pressure (P₁)

P₂ : P₁ => 3P/P

P₂ : P₁ => 3 : 1

Therefore, the ratio of the final pressure to the initial pressure is 3 : 1

Which of the following changes lead to a decrease in entropy?
a. mixing of pure gases
b. sugar dissolving in coffee
c. melting snow
d. the sublimation (vaporization) of dry ice (solid carbon dioxide)
e. halving the volume of a gas

Answers

Answer:

halving the volume of a gas

Explanation:

Entropy refers to the degree of disorderliness of a system. The greater the volume of a gas, the greater its entropy. The entropy of a system is directly proportional to its volume.

Hence a decrease in the volume of a gas leads to a decrease in its entropy. Ultimately, if the volume of a given mass of gas is halved, its entropy decreases according.

Answers

Answer:

Dissolves a chemical sample well at high temperatures.

Does not dissolve a chemical sample well at low temperatures.

Explanation:

Recrystallization involves the dissolution of the solute in a solvent at high temperature. As the solution cools, it becomes saturated and the solute crystallizes out of the solution.

A good recrystallization solvent must only dissolve the solute at high temperature and must not dissolve it at low temperature. Hence, these are the two conditions required for any good recrystallization solvent.

Imagine that you are developing a TLC plate, but you get distracted and forget to take the TLC plate out. Later, when you remove your TLC plate from the developing chamber, you notice that the solvent front has reached the top of the TLC plate. How will the Rf values from this TLC plate compare with those of a student who stopped developing their TLC plate before the solvent front reached the top of the plate

Answers

Answer:

The full form of TLC is Thin layer chromatography which is used in separating non volatile mixtures.

Explanation:

In the context, the Rf values could not be read properly or determined properly and accurately if the solvent front flows to the top of the plate. If the solvent reaches the plate's top, then the Rf values reading will be different from the TLC plate where the solvent did not reach the plate's top.

If the solvent front reaches the top, then it is not possible to accurately determine draw the line and to determine how far the spot went. And thus it would be difficult to solve the ratio as the plate would keep advancing or developing and also the compound spot keeps rising. As a result, spots reaches higher or rises than the normal rise but the solvent front does not change, it remains same. Thus, the Rf value would be completely off.

4. A solution contains 62.1 g of ethylene glycol dissolved in 250.0 g of H2O. Calculate the mass % of ethylene glycol

Answers

Answer:

Explanation:

% mass of Ethylene glycol =(  mass of ethylene glycol/ mass of solution )x100%

                        =  62.1 g/ (62.1  +  250 )   x 100%

                       = 24.24%

Mass percentage is a term that represents the concentration, basically mass by mass percentage. It tells about the percentage of a component in a whole component. Therefore, the mass % of ethylene glycol is  24.24%.

What is percentage by mass?

Mass percentage represents the the percentage of each element that is making a particular compound. Mass percentage does not have any unit as numerator and denominator contains the same unit.

Mathematically,

Percentage of mass = (component’s mass ÷ total mass) x 100%

% mass of Ethylene glycol =(  mass of ethylene glycol/ mass of solution)x100%

% mass of Ethylene glycol =  62.1 g/ (62.1  +  250 )   x 100

                                             = 24.24%

Therefore, the mass % of ethylene glycol is  24.24%.

In run 1, you mix 7.9 mL of the 43 g/L MO solution (MO molar mass is 327.33 g/mol), 3.13 mL of the 0.040 M SnCl2 in 2.0 M HCl solution, 5.49 mL of 2.0 M HCl solution, and 3.43 mL of 2.0M NaCl solution. What is the [H3O+]? Remember that there is a contribution of H3O+ from two solutions.

Answers

Answer:

Concentration of H3O⁺  [H3O⁺] = 0.864 M

Explanation:

Given that:

The mass concentration of MO = 43 g/L

The volume of MO = 7.9 mL = 7.9 × 10⁻³ L

Recall that

The mass number of MO = Mass concentration of MO × Volume of MO

The mass number of MO = (43 g/L) * (7.9 × 10⁻³ L)

The mass number of MO =  0.3397 g

number of  moles of MO = (mass number of MO) / (molar mass of MO)

number of  moles of MO = (0.3397 g) / (327.33 g/mol)

moles of MO = 0.00104 mol

The total volume = 7.9 mL + 3.13 mL + 5.49 mL + 3.43 mL

The total volume = 19.95 mL = 19.95 × 10⁻³ L

Concentration of MO [MO} =(number of moles of MO) / (total volume)

[MO] = 0.00104 mol  /  19.95 × 10⁻³ L

[MO] = 5.2130 × 10⁻⁸ M

the number of moles of H3O⁺ = molarity of HCl in the solution × the volume of HCl in solution

the number of moles of H3O⁺ = [(2.0 M) * (3.13 mL)] + [(2.0 M) * (5.49 mL)]

the number of moles of H3O⁺ = 17.24 mmol

Concentration of H3O⁺  [H3O⁺] = (the number of moles of H3O⁺) / (total volume)

Concentration of H3O⁺  [H3O⁺] = (17.24 mmol) / (19.95 mL)

Concentration of H3O⁺  [H3O⁺] = 0.864 M

The Concentration of H3O⁺  [H3O⁺] is 0.864 M

Calculation of the H3O⁺ concentration:

But before that following calculations should be needed.

The mass number of MO = Mass concentration of MO × Volume of MO

= (43 g/L) * (7.9 × 10⁻³ L)

=  0.3397 g

Now

number of  moles of MO = (mass number of MO) / (molar mass of MO)

= (0.3397 g) / (327.33 g/mol)

= 0.00104 mol

Now

The total volume = 7.9 mL + 3.13 mL + 5.49 mL + 3.43 mL

= 19.95 mL

= 19.95 × 10⁻³ L

Now

Concentration of MO [MO} =(number of moles of MO) / (total volume)

= 0.00104 mol  /  19.95 × 10⁻³ L

5.2130 × 10⁻⁸ M

Now

the number of moles of H3O⁺ = molarity of HCl in the solution × the volume of HCl in solution

= [(2.0 M) * (3.13 mL)] + [(2.0 M) * (5.49 mL)]

= 17.24 mmol

Now

Concentration of H3O⁺  [H3O⁺] = (the number of moles of H3O⁺) / (total volume)

= (17.24 mmol) / (19.95 mL)

= 0.864 M

Hence, The Concentration of H3O⁺  [H3O⁺] is 0.864 M

From a 2.875 g sample containing only iron, sand, and salt, 0.660 g of iron and 1.161 g of sand were separated and recovered. What was the percent of salt in the original sample

Answers

Answer:

36.66%

Explanation:

Step 1: Given data

Mass of iron: 0.660 gMass of sand: 1.161 gMass of the sample: 2.875 gMass of salt: ?

Step 2: Calculate the mass of salt

The mass of the sample is equal to the sum of the masses of the components.

m(sample) = m(iron) + m(sand) + m(salt)

m(salt) = m(sample) - m(iron) - m(sand)

m(salt) = 2.875 g - 0.660 g - 1.161 g

m(salt) = 1.054 g

Step 3: Calculate the percent of salt in the sample

We will use the following expression.

%(salt) = m(salt) / m(sample) × 100%

%(salt) = 1.054 g / 2.875 g × 100% = 36.66%

The percent of salt in the original sample containing only iron, sand, and salt is 36.66%.

What is salt?

Salt is a mineral made up of primarily sodium chloride.

Seawater contains a vast amount of salt.

Given,

The total mass of the sample is 2.875 g

Mass of iron is  0.660 g

Mass of sand is 1.161 g

Step 1: To find the mass of salt

The total mass of the sample = the sum of the masses of the compounds

m(sample) = m(iron) + m(sand) + m(salt)

2.875 g =  0.660 g + 1.161 g + m(salt)

m(salt) = 2.875 g - 0.660 g - 1.161 g

m(salt) = 1.054 g

Step 2: Calculate the percent of salt in the sample

[tex]\%(salt) = \dfrac{m(salt) }{m(sample)} \times 100\%\\\\\\\%(salt) = \dfrac{1.054 g }{2.875 g} \times 100\% = 36.66\%[/tex]

Thus, the percentage of salt in the sample is 36.66%.

Answers

Answer:

The concentration of fructose-6-phosphate is 1.50x10⁻³M

Explanation:

Gibbs Free energy, ΔG°, is defined as:

ΔG° = -RTln K

Where ΔG° = 1670J/mol

R is gas constant = 8.314J/molK

T is absolute temperature (25°C + 273.15 = 298.15K)

Thus, equilibrium constant, k, is:

1670J/mol = -8.314J/molK* 298.15K ln K

-0.6737 = ln K

0.5098 = K

K of the reaction:

G6P ⇄ F6P

is:

K = 0.5098 = [F6P] / [G6P]

As [G6P] is 2.95x10⁻³M:

0.5098 = [F6P] / [2.95x10⁻³M]

[F6P] = 1.50x10⁻³M

Carbon-14 to decay to 3.125 grams?

Answers

Answer:

26150 years

Explanation:

First we need to determine the number of half lives -- not years -- it'll take for 100g (of any element) to decay to 3.125 g

First Half Life 100/2 = 50

Seconf Half Life 50/2 = 25

Third Half Life 25/2 = 12.5

Fourth Half Life 12.5/2 = 6.25

Fifth Half Life 6.25/2 = 3.125

So it'll take 5 half lives for 100g to decay to 3.125g.

If the Half Life of Carbon-14 is 5230 and it will take 5 half lives, to determine the number of years we just need to multiply 5*5230

5*5230 = 26150

This means that it will take 26150 years for 100g Carbon-14 to decay to 3.125g.
