Answers

Answer 1

Answer:

Oxidized : CO

Reduced: Fe

Oxidizing agent: Fe2O3

Reducing agent: CO

Explanation:

Loss of electrons is oxidation while gaining of electrons is reduction.

CO is a reducing agent, Fe2O3 is an oxidizing agent.

Each carbon atom is oxidized in CO. CO is the reducing agent

Each Fe atom in FeO3 is reduced. FeO3 is the oxidizing agent

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.

Answers

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.

What happens to a glass of sugar solution when sugar is added to it?

The number of moles of water increases.
The number of moles of water decreases.
The molarity of the solution increases.
The molarity of the solution decreases.

Answers

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.

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.

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.

Hope this helps!

2.0 kilograms of lithium hydroxide can “scrub”, or remove, how many liters of carbon dioxide at standard conditions?

Answers

Answer:

0.94 L

Explanation:

The equation of the reaction is;

2LiOH + CO2 -----> Li2CO3 + H2O

Number of moles LiOH = 2.0/23.95 g/mol = 0.084 moles

2 moles of LiOH scrubs 22.4 L of CO2

0.084 moles of LiOH scrubs 0.084 moles × 22.4/2

= 0.94 L

The volume of a gas at 6.0 atm is 2.5 L. What is the volume of the gas at 7.5 atm at

the same temperature? (5 points)

1) 1.0 L

2) 1.5 L

3) 2.0 L

4) 3.0L

Answer:

2.0 L

Option C) 2.0L is the correct answer.

Hence, at the same temperature, as the pressure is increased to the given value, the volume of the gas decreases to 2.0L.

Boyle's law

Boyle's law states that "the volume V of a given quantity of gas is inversely proportional to its pressure P as long as temperature remains constant.

Boyle's law is expressed as;

P₁V₁ = P₂V₂

Given the data in the question;

Initial Volume V₁ = 2.5LInitial pressure P₁ = 6.0atmFinal pressure P₂ = 7.5atmFinal volume V₂ = ?

To determine the final volume of the gas, we substitute our given values into the expression above.

P₁V₁ = P₂V₂

V₂ = P₁V₁ /  P₂

V₂ = ( 6.0atm × 2.5L ) /  7.5atm

V₂ = 15Latm / 7.5atm

V₂ = 2.0L

Option C) 2.0L is the correct answer.

Hence, at the same temperature, as the pressure is increased to the given value, the volume of the gas decreases to 2.0L.

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.

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.)
