How many liters would you need to make a 0.7 M solution if you have 8.30 mol of
Potassium Chloride?

Answers

Answer 1

The answer for the following problem is mentioned below.

Therefore the volume of potassium chloride solution is 11.8 litres.

Explanation:

Given:

molarity of the potassium chloride solution (m) = 0.7 M

no of moles present in the potassium chloride solution (n) = 8.30 moles

To find:

volume of the potassium chloride solution (V)

We know;

m = [tex]\frac{n}{V}[/tex]

Where;

m represents the molarity of potassium chloride solution

n represents the no of moles of potassium chloride solution

V represents the volume of the solution

So;

0.7 = [tex]\frac{8.30}{V}[/tex]

V = 11.8 litres

Therefore the volume of potassium chloride solution is 11.8 litres.

Where does filtration of the blood occur within the kidneys?

Answers

Answer:

takes place in the glomerulus

Explanation:

which is the vascular beginning of the nephron . Approximately one-fourth of the blood flow from cardiac output circulates through the kidney, the greatest rate of blood flow for any organ .

The filtration of the blood in the kidneys occurs in the glomerulus, where most solutes are filtered out by glomerular filtration.    


Filtration of the Blood in the Kidneys:

The filtration of the blood in the kidneys primarily occurs in the glomerulus. The glomerulus is a network of capillaries at the beginning of a nephron. When blood flows through the glomerulus, most solutes, except for proteins, are filtered out into the glomerulus by a process called glomerular filtration. The filtrate is then collected in the renal tubules, where it undergoes further processing to form urine.

This process begins with glomerular filtration, continues with tubular reabsorption in the proximal convoluted tubule (PCT), and ends with tubular secretion. Finally, the collecting ducts gather the filtrate, now called urine, which is passed on to the ureters and then eliminated from the body.

B) What is the theoretical yield of NH3 in grams?

Answers

Answer:

The answer to your question is a) N₂     b) 3.04 g of NH₃

Explanation:

Data

mass of H₂ = 2.5 g

mass of N₂ = 2.5 g

molar mass H₂ = 2.02 g

molar mass of N₂ = 28.02 g

molar mass of NH₃ = 17.04 g

Balanced chemical reaction

                3H₂  +  1 N₂   ⇒   2NH₃

A)

Calculate the theoretical yield 3H₂ / N₂ = 3(2.02) / 28.02 = 0.22

Calculate the experimental yield H₂/N₂ = 2.5/2.5 = 1

Conclusion

The limiting reactant is N₂ (nitrogen) because the experimental proportion was higher than the theoretical proportion.

B)

             28.02 g of N₂ -------------------- (2 x 17.04) g of NH₃

               2.5 g of N₂    --------------------   x

                            x = (2.5 x 2 x 17.04) / 28.02

                            x = 85.2 / 28.02

                           x = 3.04 g of NH₃

A catalytic converter in an automobile uses a palladium or platinum catalyst to convert carbon monoxide gas to carbon dioxide according to the following reaction: 2CO(g) + O2 (g) --> 2CO2(g) A chemist researching the effectiveness of a new catalyst combines a 2.0 : 1.0 mole ratio mixture of carbon monoxide and oxygen gas (respectively) over the catalyst in a 2.45L flask at a total pressure of 740 torr and a temperature of 552 C . When the reaction is complete, the pressure in the flask has dropped to 552 torr. What percentage of the carbon monoxide was converted to carbon dioxide?

Answers

Answer:

the fraction of CO reacted is 0.76 or 76.0 %

Explanation:

Step 1: Data given

a new catalyst combines a 2.0 : 1.0 mole ratio mixture of carbon monoxide and oxygen gas

Volume = 2.45 L

Total pressure = 740 torr

Temperature = 552 °C = 825 K

Pressure decreases to 552 torr

Step 2: The balanced equation

2CO(g) + O2 (g) --> 2CO2(g)

Step 3: Calculate the percentage of the CO was converted to CO2

P1/n1 = P2/n2

⇒P1 = the initial pressure = 740 torr

⇒n1 = the initial number of moles = 2.0 moles CO and 1 mol of O2 = 3.0 moles

⇒P2 = the final pressure = 552 torr

⇒n2 = the final number of moles = TO BE DETERMINED

n2 = n1 * P2/P1

n2 =3.0 * 552 torr / 740 torr

n2 = 2.24 moles

Step 4: Calculate total moles of CO

Suppose X = the fraction of CO

final = 2*(x) + 3*(1-x)

2.24 = 2x + 3 - 3x

2.24 = -X + 3

-0.76 = -X

X = 0.76

This means the fraction of CO reacted is 0.76 or 76.0 %

The fraction or the percentage of the carbon monoxide converted to carbon dioxide is 76%.

Given:

Ratio of new catalyst to the mole ratio of carbon dioxide and oxygen  = 2:1

Volume = 2.45 L

Temperature = 825 K

Pressure = 740 torr

The reaction is:

2CO(g) + O₂ (g) [tex]\rightarrow[/tex] 2CO₂

From the reaction, the amount of CO converted into carbon dioxide is:

[tex]\dfrac{\text{P}_1}{\text n _1}&=\dfrac{\text{P}_2}{\text n _2}[/tex]

Where,

P₁ = initial pressure

n₁ = number of moles (initial)

P₂ = final pressure

n₂ = final number of moles

Now, calculating the n₂:

[tex]\text n_2 &= \dfrac{\text n_1 \times \text P_2}{\text P_1}[/tex]

[tex]\text n_2 &= \dfrac{3 \times 552}{740}[/tex]

n₂ = 2.24 moles.

Now, the total moles of carbon monoxide is:

2.24 = 2 x Y + 3 x (1 - Y)

2.24 = 2Y + 3 - 3Y

Y = 0.76

Thus, the number of a fraction of CO is 0.76.

Which is the correct order of increasing standard molar entropy for the noble gases?


He ≤ Ne ≤ Kr ≤ Ar

He ≤ Ne ≤ Ar ≤ Kr

Ne ≤ He ≤ Ar ≤ Kr

Kr ≤ Ar ≤ Ne ≤ He

Answers

Answer:

The correct order of increasing standard molar entropy for the noble gases is He ≤ Ne ≤ Ar ≤ Kr

Explanation:

Entropy is the measure of degree of disorderliness or randomness of a substance. Entropy increases with increasing number of electron present in an atom due to increased repulsive force of the electrons. Therefore, the standard entropy of a substance increases with an increase in their atomic masses.

For the given noble gases in this question, Helium (He) has the least atomic mass while Krypton (Kr) has the highest atomic mass.

Thus, the correct order of increasing standard molar entropy for the noble gases is He ≤ Ne ≤ Ar ≤ Kr

Final answer:

The increasing standard molar entropy for noble gases is He ≤ Ne ≤ Ar ≤ Kr, due to growing atomic number and electronic complexity down the group.

Explanation:

The correct order of increasing standard molar entropy for the noble gases is He ≤ Ne ≤ Ar ≤ Kr. This is because entropy generally increases with atomic number due to increased electronic complexity and atomic mass. As you move down the group in the periodic table, noble gases have more electrons that can occupy a greater volume of space and therefore have higher entropy.

Given the reactant side of the total ionic equation for the neutralization reaction of ammonium hydroxide (NH4OH) with hydrochloric acid (HCl), write the total ionic equation (also known as the complete ionic equation) by entering both the reactant and the product species, separated by the reaction arrow.

Answers

Final answer:

The total ionic equation for the neutralization reaction of ammonium hydroxide with hydrochloric acid expresses all components as ions and after removing spectator ions, the net ionic equation is OH⁻(aq) + H⁺(aq) → H₂O(l).

Explanation:

To write the total ionic equation for the neutralization reaction of ammonium hydroxide (NH₄OH) with hydrochloric acid (HCl), we need to express all soluble substances as ions. Ammonium hydroxide can be represented as NH₄⁺(aq) and OH⁻(aq) since it partially dissociates in solution. The hydrochloric acid fully dissociates into H⁺(aq) and Cl⁻(aq).

The total ionic equation is as follows:

NH₄⁺(aq) + OH⁻(aq) + H⁺(aq) + Cl⁻(aq) → NH₄⁺(aq) + Cl⁻(aq) + 2H₂O(l)

The net ionic equation, which shows the actual chemical change, is produced by removing the spectator ions (NH₄⁺ and Cl-), resulting in: OH⁻(aq) + H⁺(aq) → H₂O(l)

Final answer:

The total ionic equation for the neutralization reaction between ammonium hydroxide and hydrochloric acid is NH4+(aq) + OH-(aq) + H+(aq) + Cl-(aq) → NH4+(aq) + Cl-(aq) + H2O(l), with H+(aq) + OH-(aq) → H2O(l) as the net ionic equation.

Explanation:

The total ionic equation for the neutralization reaction of ammonium hydroxide (NH4OH) with hydrochloric acid (HCl) shows each species in its ionic form. The reactants ammonium hydroxide and hydrochloric acid dissociate in water to form NH4+ (aq), OH- (aq), H+ (aq), and Cl- (aq). In a complete ionic equation, all of the ions are shown as they exist in solution before and after the reaction:

NH4+ (aq) + OH- (aq) + H+ (aq) + Cl- (aq) → NH4+ (aq) + Cl- (aq) + H2O(l)

After the reaction, ammonium ions and chloride ions remain in solution while water is formed as the product. However, since ammonium ions (NH4+) are spectator ions in this reaction, they can be omitted to provide the net ionic equation:

H+ (aq) + OH- (aq) → H2O(l)

The net ionic equation indicates that the hydrogen ions (H+ from the hydrochloric acid) combine with the hydroxide ions (OH- from the ammonium hydroxide) to form water, which is a characteristic outcome of a neutralization reaction.

Answers

Answer:

C2H5OH--- aqueous solution contains mostly molecules

Na2SO4---aqueous solution contains ions

HCN ---aqueous solution contains mostly molecules and a few ions

Explanation:

Only strong electrolytes dissociate completely in solution to form ions. Hence aqueous solutions of strong electrolytes comprises of ions which conduct electricity.

Weak electrolyte aqueous solutions contain mostly molecules since they ionize only to a very small extent in solution.

Nonelectrolytes remain molecular in solution and do not conduct electricity at all.

Final answer:

When dissolved in water, nonelectrolytes like ethanol produce primarily molecules, strong electrolytes like Na2SO4 generate only ions, and weak electrolytes like HCN result in a mix of mostly molecules with a few ions.

Explanation:

The type of substances present in a solution can be predicted based on the type of electrolyte. C2H5OH (ethanol), a nonelectrolyte, will mainly form molecules when dissolved in water as it does not ionize. Na2SO4, a strong electrolyte, will fully dissociate in water and produce only ions. HCN (hydrocyanic acid), a weak electrolyte, will produce mostly molecules with a few ions as it only partially ionizes in an aqueous solution.

Answers

Answer:

Mole fraction of [tex]NH_{3}[/tex] in solution is 0.0597.

Explanation:

Molar mass of [tex]H_{2}O[/tex] = 18.015 g/mol

No. of moles = (mass)/(molar mass)

So, 15.0 g of [tex]NH_{3}[/tex] = [tex]\frac{15.0}{17.031}[/tex] moles of [tex]NH_{3}[/tex] = 0.8807 moles of [tex]NH_{3}[/tex]

      250 g of [tex]H_{2}O[/tex] = [tex]\frac{250}{18.015}[/tex] moles of [tex]H_{2}O[/tex] = 13.88 moles of [tex]H_{2}O[/tex]

So, Mole fraction of [tex]NH_{3}[/tex] in the solution = (no.of moles of [tex]NH_{3}[/tex] )/(total no. of moles) = [tex]\frac{0.8807}{0.8807+13.88}[/tex] = 0.0597

Hence, mole fraction of [tex]NH_{3}[/tex] in solution is 0.0597.

b. 4.0 mol of magnesium nitride and 2.0 mol excess magnesium
c. 6.0 mol of magnesium nitride and 3.0 mol excess nitrogen
d. No product because the reactants are not in the correct mole ratio

Answers

Answer:

The correct answer is A

We'll have 2.0 moles of magnesium nitride produced  and and excess of 2.0 moles nitrogen gas

Explanation:

Step 1: Data given

Number of moles nitrogen gas (N2) = 4.0 moles

Number of moles magnesium = 6.0 moles

Step 2: The balanced equation

3Mg + N2 → Mg3N2

Step 3: Calculate the limiting reactant

For 3 molesmagnesium (Mg) we need 1 mol nitrogen gas  (N2) to react, to produce 1 mol magnesium nitride (Mg3N2)

Magnesium is the limiting reactant. It will completely be consumed 6.0 moles. Nitrogen is in excess. There will react 6.0 / 3 = 2.0 moles

There will remain 4.0 - 2.0 = 2.0 moles N2

Step4: Calculate moles Mg3N2

For 3 molesmagnesium (Mg) we need 1 mol nitrogen gas  (N2) to react, to produce 1 mol magnesium nitride (Mg3N2)

For 6.0 moles Mg we'll have 6.0 / 3 = 2.0 moles Mg3N2

The correct answer is A

We'll have 2.0 moles of magnesium nitride produced  and and excess of 2.0 moles nitrogen gas

Final answer:

The correct answer is a. 2.0 moles of magnesium nitride are formed when 6.0 moles of magnesium react with 4.0 moles of nitrogen, leaving 2.0 moles of nitrogen unreacted as excess.

Explanation:

The formation of magnesium nitride involves a reaction between magnesium metal and nitrogen gas. Magnesium forms a Mg2+ ion, which is a cation, by losing two electrons. Nitrogen, a non-metal, forms an anion with a charge of 3-. Therefore, the formula for magnesium nitride is Mg3N2, indicating that three magnesium ions react with two nitrogen ions to form one formula unit of magnesium nitride.

The balanced chemical equation for the formation of magnesium nitride is:

3Mg + N2 → Mg3N2

Given that 4.0 moles of nitrogen is reacted with 6.0 moles of magnesium, we can determine the limiting reactant and calculate the product formed. The molar ratio of Mg to N2 in the equation is 3:1, meaning three moles of Mg are required for every mole of N2. Therefore, 6.0 moles of Mg would completely react with 2.0 moles of N2 to produce magnesium nitride. Since we started with 4.0 moles of nitrogen, we have an excess of nitrogen, and magnesium is the limiting reactant.

The result is that all of the magnesium reacts and you would produce 2.0 moles of magnesium nitride with 2.0 moles of nitrogen left over as excess. Hence, the correct answer to the student's question is option a.

Consider the following errors that could be made when running TLC. Indicate what should be done to correct the error. a. A two-component mixture containing 1-octene and 1, 4-dimethylbenzene gave only one spot with an Rf value of 0.95. The solvent used was acetone.

Answers

Final answer:

To correct a high Rf value of 0.95 in TLC, decrease the polarity of the mobile phase by using a less polar solvent and ensure the sample is not too concentrated for improved separation and accurate Rf values.

Explanation:

When running Thin Layer Chromatography (TLC), a high Rf value of 0.95 implies that the sample has moved almost as far as the solvent front, suggesting that the mobile phase is too polar. To correct this and achieve better separation, the polarity of the mobile phase should be decreased.

Using a less polar solvent, such as a mixture of hexanes and ethyl acetate, instead of pure acetone might provide better separation of the components 1-octene and 1, 4-dimethylbenzene.

Additionally, ensuring that the samples are not too concentrated can lead to more accurate Rf values and better spot definition. A correctly run TLC should show the desired component with an Rf around 0.35, separated from other spots by at least 0.2 Rf units.

A balloon has been fillled to a volume of 1.90L with 0.09Omal of helium gas. If 0.0210mol of additional helium is added to the balloon with the temperature and pressure are held constant, what is the new volume of the balloom

Answers

The new volume of the balloon is approximately 2.33 liters when additional helium is added.

To find the new volume of the balloon, we can use Avogadro's Law, which states that the volume of a gas is directly proportional to the number of moles of gas, provided the temperature and pressure are constant. The formula for Avogadro's Law is:

[tex]\frac{V_1}{n_1} = \frac{V_2}{n_2}[/tex]

where:

V1 is the initial volume (1.90 L)n1 is the initial number of moles (0.0920 mol)V2 is the final volumen2 is the final number of moles (0.0920 mol + 0.0210 mol = 0.1130 mol)

We can rearrange the formula to solve for V2:

V2 = (V1 * n2) / n1

Substituting the values, we get:

[tex]V_2 = \frac{(1.90 \, \text{L} \times 0.1130 \, \text{mol})}{0.0920 \, \text{mol}}[/tex]

V2 ≈ 2.33 L

Therefore, the new volume of the balloon is approximately 2.33 liters.

If a sample gas is collected over water. The atmospheric pressure is 778 mm and the temperature is 30°C. If the vapor pressure of water at 30 C is 31.8 mm, what is the pressure of the gas?

Answers

Answer:

P = 746.2 mmHg or 0.9818 atm

Explanation:

First, we have a sample gas (This can be hydrogen, argon, nitrogen or any other gas) that was collected with a pressure of 778 mmHg. We also know the vapor pressure which is 31.8 mmHg. To get the pressure that the gas is exerting, we can assume that the atmospherical pressure is the total pressure of the whole system. Therefore we can use the following expression:

Pt = Pw + Pg   (1)

Where:

Pt: total pressure

Pw: water pressure

Pg: gas pressure

From (1) we can solve for the gas pressure and have:

Pg = Pt - Pw

Replacing the data we have:

Pg = 778 - 31.8

Pg = 746.2 mmHgThis would be the pressure of the gas

If you want this value in atm, you should divide it by 760 mmHg (Conversion from mmHg to atm):

Pg = 746.2 / 760

Pg = 0.9818 atm

Select the more electronegative element in each pair.a.Cl or Fb.Se or Oc.N or Asd.Na or Mg

Answers

Answer:

Explanation:

Electronegativity is a measure of how strongly atoms attract electrons to themselves.

Process

Look for the electronegativity of each element and compare.

a) Cl = 3.16   F = 3.98          Fluorine has a higher electronegativity

b) Se = 2.55 O = 3.44         Oxygen has a higher electronegativity

c) N = 3.04 As = 2.18         Nitrogen has a higher electronegativity

d) Na = 0.93 Mg = 1.31       Magnesium has a higher electronegativity

Final answer:

The more electronegative elements among the pairs are F (fluorine), O (oxygen), N (nitrogen), and Na (sodium). These are determined based on their positions in the periodic table, where electronegativity generally increases from left to right and decreases from top to bottom.

Explanation:

Electronegativity is a measure of the ability of an atom to attract a bonding pair of electrons. The Pauling scale is the most commonly used electronegativity scale and it ranges from 0 to 4.

In the pair Cl (chlorine) and F (fluorine), F is more electronegative.In the pair Se (selenium) and O (oxygen), O is more electronegative.In the pair N (nitrogen) and As (arsenic), N is more electronegative.In the pair Na (sodium) and Mg (magnesium), Na is more electronegative.

Generally, electronegativity increases from left to right across a period and decreases moving down a group or column in the periodic table. Therefore, elements on the top right corner of the periodic table (excluding noble gases) are the most electronegative.
