An aqueous solution of a vanadium chloride salt is electrolyzed by a current of 3.00 A passing through the solution for 60.0 min. If 5.70 g of vanadium is produced at the cathode during this time, what is the likely formula unit for the vanadium salt

Answers

From the information in the question, the formula unit of the salt is given as VCl.

The quantity of charge produced is obtained from;

Q = It

I = current (3 A), t = time (3600 s)

Q = 3 A × 3600 s

Q = 10800 C

Now we need to find the number of electrons transferred as follows;

51 g of Vanadium is deposited by 96500n C

5.70 g is deposited by 10800 C

5.70 × 96500n = 51 × 10800

n =  51 × 10800/5.70 × 96500

n = 1

The formula of the salt is VCl.

Zingerone, one of the flavor molecules in ginger,
contains only C, H, and O. Combustion of 10.0 g
of zingerone produces 24.91 g of CO2 and
6.522 g of H20. Determine the molar mass of the
compound if it is between 150.0 and 220.0 g/
mol. Provide an answer to four significant
figures.

Answers

The molecular formula of the compound is C12H15O3 hence the molar mass of the compound is 207 g/mol.

We need to obtain the number of moles of carbon, hydrogen and oxygen in the compound;

Carbon = 24.91 g/44g/mol × 1 mole of carbon = 0.566 moles

Mass of carbon =  0.566 moles × 12 g/mol = 6.792 g

Number of moles of hydrogen = 6.522 g/18 g/mol × 2 moles = 0.725 moles

Mass of hydrogen = 0.725 moles  × 1 g/mol = 0.725 g

Mass of oxygen = 10 - (6.792 g + 0.725 g) = 2.483 g

Number of moles of oxygen = 2.483 g/16 g/mol = 0.155 moles

Now we must divide through by the lowest number of moles;

C - 0.566/0.155   H - 0.725/0.155     O - 0.155/0.155

C - 4                    H - 5                        O - 1

The simplest formula is C4H5O Recall that the molar mass of the compound lies between 150.0 and 220.0 g/mol

4(12) + 5(1) + 16 = 69

Hence; n = 3 and the molecular formula of the compound is C12H15O3

The molar mass of the compound is; 12(12) + 15(1) + 3(16) = 207 g/mol

Which best describes the energy change that takes place during deposition?
Heat energy released by the substance
Heat energy is maintained by the substance
Heat energy is slowly gained by the substance
Heat energy is quickly absorbed by the substance

Answers

Answer:

heat energy released by the substance

The energy change that takes place during deposition is that heat energy is released by the substance. This statement is true about deposition.

Deposition is a phase transition that occurs when a gas is converted directly to a solid without passing through the liquid state. During deposition, energy is released by the gas particles and absorbed by the surface, resulting in a decrease in the energy of the gas particles and an increase in the energy of the surface particles.As a result, the substance releases heat energy as it changes from a gas state to a solid state.

Therefore, the correct option is:Heat energy released by the substance.

C. The intramolecular bonds in ethanol are stronger than the intramolecular bonds in acetone.

D. The intermolecular forces in acetone are stronger than the intermolecular forces in ethanol.

Answers

Answer:

see below

Explanation:

1. The temperatures at which a substance changes phases indicate the relative strength of the forces between molecules in the substance.

2. solid, liquid, gas

3. The forces between water molecules break, and the bonds between the atoms in water are unchanged.

4. The forces strengthen, and the molecule structure becomes more rigid.

5. The intermolecular forces in ethanol are stronger than the intermolecular forces in acetone.

The the degree of intermolecular interaction between molecules determines the magnitude of boiling point of the substance.

During phase change, a substance moves from one state of matter to another. The temperature at which a phase change occurs is determined by the strength of the forces between molecules in the substance. The relative magnitude of intermolecular forces between molecules in different states of matter is solids > liquids > gases.

During boiling, energy is imparted to the molecules of a liquid. When this occurs, the forces between water molecules break, and the bonds between the atoms in water are unchanged.

We must recall that the molecules of a substance are in constant random motion. The average kinetic energy of molecules is proportional to temperature. As a sample of  calcium carbonate is cooled, the forces between molecules strengthen, and the molecule structure becomes more rigid.

The magnitude of intermolecular interaction affects the boiling point of a liquid. The stronger the magnitude of intermolecular interaction,the higher the boiling point. As such, ethanol having hydrogen bonds between its molecules has a higher boiling point than acetone which only posses weaker dipole - dipole interactions.

Under an O2(g) pressure of 1.00 atm, 28.31 mL of O2(g) dissolves in 1.00 L H2O at 25 °C. What will be the molarity of O2 in the saturated solution at 25 °C when the O2 pressure is 4.47 atm? Assume that the solution volume remains at 1.00 L.

Answers

In the first case, the molarity of oxygen gas is 0.0012 mol/L. In the second case, the molarity of oxygen gas is 0.0052 mol/L .

We have to obtain the number of moles of oxygen as follows;

P = 1.00 atm

V = 28.31 mL or 0.02831 L

n = ?

R = 0.082 atm LK-1mol-1

T = 25 °C + 273 = 298 K

n = PV/RT

n=  1.00 atm × 0.02831 L/ 0.082 atm LK-1mol-1 ×  298 K

n = 0.0012 moles

Molarity = Number of moles/Volume = 0.0012 moles/1.00 L =  0.0012 mol/L

For the second case;

P = 4.47 atm

V = 28.31 mL or 0.02831 L

n = ?

R =  0.082 atm LK-1mol-1

T = 25 °C + 273 = 298 K

n = PV/RT

n = 4.47 atm ×  0.02831 L/0.082 atm LK-1mol-1 × 298 K

n = 0.1265/24.436

n = 0.0052 moles

Molarity of oxygen = 0.0052 moles/1.00 L = 0.0052 mol/L
