Which of the four is least like the other three? A)Platinum B)Ivory C)Silver D)Gold​

Answers

Answer:

B) Ivory

Explanation:

Ivory is a hard, white material from the tusks and teeth of animals, that consists mainly of dentine, one of the physical structures of teeth and tusks.

Platinum, Silver, and Gold are precious metals, meaning they are rare metallic chemical elements of high economic value, shiny, hard, strong with high melting points

Ivory is regarded as the least of the options. Ivory consists of dentine and

are usually found in the tusks and teeth of animals such as elephants. They

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

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.

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.

A containing vessel holds a gaseous mixture of nitrogen and butane. Thepressure in the vessel at 126.9 Cis 3.0 atm. At 0 C, the butane completelycondenses and the pressure drops to 1.0 atm. Calculate the mole fraction of nitrogenin the original gaseous mixture.

Answers

A vessel that contains a mixture of nitrogen and butane has a pressure of 3.0 atm at 126.9 °C and a pressure of 1.0 atm at 0 °C. The mole fraction of nitrogen in the mixture is 0.33.

A vessel contains a gaseous mixture of nitrogen and butane. At 126.9 °C (400.1 K) the pressure is due to the mixture is 3.0 atm.

We can calculate the total number of moles using the ideal gas equation.

[tex]P \times V = n \times R \times T\\\\n = \frac{P \times V}{R \times T} = \frac{3.0 atm \times V}{0.082 atm.L/mol.K \times 400.1 K} = 0.091 mol/L \times V[/tex]

At 0 °C (273.15 K), the pressure due to the gaseous nitrogen is 1.0 atm.

We can calculate the moles of nitrogen using the ideal gas equation.

[tex]P \times V = n \times R \times T\\\\n = \frac{P \times V}{R \times T} = \frac{1.0 atm \times V}{0.082 atm.L/mol.K \times 400.1 K} = 0.030 mol/L \times V[/tex]

The mole fraction of nitrogen in the mixture is:

[tex]X(N_2) = \frac{0.030 mol/L \times V}{0.091 mol/L \times V} = 0.33[/tex]

A vessel that contains a mixture of nitrogen and butane has a pressure of 3.0 atm at 126.9 °C and a pressure of 1.0 atm at 0 °C. The mole fraction of nitrogen in the mixture is 0.33.
