A sample of 17.0 M concentrated H2SO4 stock solution with a volume of 25.0 cm3 was diluted to final concentration of 5.0 M H2SO4 solution. Calculate, what is the amount of water that would be required to dilute the concentrated H2SO4 solution to a final concentration of 5.0 M?

Answers

Answer 1

Answer:

60 cm³ of water

Explanation:

We'll begin by calculating the volume of the diluted solution. This can be obtained as follow:

Concentration of stock solution (C₁) = 17 M

Volume of stock solution (V₁) = 25 cm³

Concentration of diluted solution (C₂) = 5 M

Volume of diluted solution (V₂) =?

C₁V₁ = C₂V₂

17 × 25 = 5 × V₂

425 = 5 × V₂

Divide both side by 5

V₂ = 425 / 5

V₂ = 85 cm³

Thus, the volume of the diluted solution is 85 cm³

Finally, we shall determine the volume of water needed to dilute the solution. This can be obtained as follow:

Volume of stock solution (V₁) = 25 cm³

Volume of diluted solution (V₂) = 85 cm³

Volume of water =?

Volume of water = V₂ – V₁

Volume of water = 85 – 25

Volume of water = 60 cm³

Therefore, 60 cm³ of water is needed to dilute the solution.

Re-word this statement: Ionic Radii are changing as you move down the column because the atoms in lower rows have more energy levels, which makes the valence electrons farther from the nucleus, so it takes less energy for them to be pulled away.
The Ionic radii are changing as you move across a row because each element has one more proton, which increases the attraction of the nucleus.

Calculate the molar mass of the following compound: Ca3P2

Answers

Answer:

The molar mass of the compound given is 182.182 g/mol.

Explanation:

To calculate the molar mass of the compound, we must multiply the number of moles of each element by the the individual molar mass of each element and add them together.

Let's start with Calcium.  The molar mass of Calcium is 40.078.  In this compound, we have three moles of Calcium, so we should multiply this number by 3.

40.078 g/mol * 3 mol = 120.234 g

Now, let's do the same for Phosphorus.

30.974 g/mol * 2 g/mol = 61.948 g

To find the molar mass of the entire compound, we should add these two values together.

120.234 g + 61.948 g = 182.182 g

Therefore, the correct answer is 182.182 g/mol.

Answer:

a) Solution 1: Solute is ethyl alcohol, solvent is water. Solution 2 and 3: Solute is salt, solvent is water.

b) Concentration by weight of solution 3: Approximately 3.85%.

c) Solution 3 has a higher concentration than solution 2.

a) Solutions and their solutes and solvents:

Solution 1: The solute is ethyl alcohol, and the solvent is water. This is because ethyl alcohol is the substance that dissolves in water to form the solution.

Solution 2: The solute is salt, and the solvent is water. Salt is the substance that dissolves in water to form the solution.

Solution 3: The solute is salt, and the solvent is water. Similar to solution 2, salt is the substance that dissolves in water to form the solution.

b) Weight concentration of solution number 3:

The weight concentration is calculated by dividing the mass of the solute (80 g of salt) by the total mass of the solution (80 g of salt + 2000 g of water):

Weight concentration = (80 g / 2080 g) * 100% ≈ 3.85%

c) Comparison of concentrations between solution 2 and 3:

Solution number 3 has a higher concentration than solution 2, as the weight concentration of solution 3 is approximately 3.85%, while the exact amount of water is not provided for solution 2 to calculate its concentration. However, solution 2 contains only 20 g of salt dissolved in 500 ml of water, which implies that the concentration will be lower than solution 3. Therefore, solution number 3 has a higher concentration compared to solution 2.

A mixture of reactants and products for the reaction shown below is at equilibrium in a 5.0 L container what would most likely happen to the equilibrium if the volume of the container will reduced to 3.0 L?

Answers

Since the volume decreased, it means that the pressure is going to rise. Thus, the equilibrium of the reaction will shift in the direction that has the least amount of moles.

The statement, that describes the equilibrium "will change in the direction with the minimum moles."

What is an equilibrium?

A condition of equilibrium has become one of balance. Chemical equilibrium is the state in which both the reactants and products are present in concentrations that have no further tendency to change with time, resulting in no observable change in the system's properties.

When volume decreases, the equilibrium shifts to favor the direction that produces fewer moles of gas. When the volume is raised, the equilibrium shifts in favor of the direction that produces the most moles of gas. Because the container's volume will be lowered from 5.0 L to 3.0 L, the pressure will rise. As a result, the equilibrium of the reaction will shift in the direction with the fewest moles. When the volume is reduced, the pressure rises. This demonstrates that a gas's pressure is inversely proportional to its volume.

Hence the correct answer is equilibrium will change in the direction with the minimum moles.

High-pressure liquid chromatography (HPLC) is a method used in chemistry and biochemistry to
purify chemical substances. The pressures used in this procedure range from around 500
kilopascals (500,000 Pa) to about 60,000 kPa (60,000,000 Pa). It is often convenient to know
the pressure in torr. If an HPLC procedure is running at a pressure of 3.20x10^8 Pa , what is its
running pressure in torr?
Express the pressure numerically in torr.

3.20 x 10^8 Pa = _____ torr

Answers

Answer:

2,400,000 torr (3 s.f.)

Explanation:

Convert the pressure from Pascal to atm first:

[tex]\boxed{1 \: atm = 101325 \:Pa }[/tex]

3.20 ×10⁸ Pa

= [(3.20 ×10⁸) ÷101325] atm

= 3158.2 atm (5 s.f.)

Convert atm to torr:

[tex]\boxed{1 \: atm = 760 \: torr}[/tex]

3158.2 atm

= (3158.2 ×760) torr

= 2400000 torr (3 s.f.)

When sugar is added to a glass of sugar solution, the molarity of the solution increases. Details about molarity can be found below, which is the third option.

What is molarity?

Molarity is a term used to identify the amount of solute, in moles, dissolved in a solvent by volume. Molarity is expressed as moles per liter (mol/L).

However, molarity is directly proportional to the amount of solute in solution. This means that as the amount of solute increases, molarity also increases.

Therefore, when sugar is added to a glass of sugar solution, the molarity of the solution increases.

Explanation:

You see, when we set out to balance chemical reaction equations, ultimately, our aim is to ensure that the number of atoms of each element on the reactant side is exactly the same as the number of atoms of the same element on the products side.

We do this by counting the number of atoms required to have a balanced reaction equation and then adding coefficients in order to have a balanced chemical reaction equation.

This is what have been done in balancing the three reaction equations shown in the answer section.
