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
however don't have much value as the other metals in the options.

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.

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

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

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.
