Explain the electroplating process of an iron key with silver. the materials provided for electroplating is AgNO3 solution, silver rod and iron key.
Answers
Answer:
See explanation
Explanation:
The process of electroplating an iron key with silver involves electrolysis.
The anode is a silver rod, the electrolyte is AgNO3 solution while the cathode is the iron key. A battery is connected to provide energy to drive the non-spontaneous electrochemical reaction.
Electrons flow from the anode to the cathode. Silver ions from the silver rod replenishes the silver that is deposited on the iron key in order to continue the electrolytic process.
The silver anode is therefore depleted in mass while the iron key increases in mass.

What is the molecular formula of the compound with a molecular weight of 112 g/mol and percent composition: 85.6% C and 14.4% H?
Select one:
a. C2H4
b. CH2
c. C4H8
d. C8H16
Answers
Answer:
Molecular formula = C₈H₁₆
Explanation:
Given data:
Percentage of hydrogen = 14.4%
Percentage of carbon = 85.6%
Molecular formula = ?
Molecular weight = 112 g/mol
Solution:
Number of gram atoms of H = 14.4/ 1.01 = 14.26
Number of gram atoms of C = 85.6/ 12 = 7.13
Atomic ratio:
C : H
7.13/7.13 : 14.26/7.13
1 : 2
C : H = 1 : 2
Empirical formula is CH₂
Molecular formula:
Molecular formula = n (empirical formula)
n = molar mass of compound / empirical formula mass
n = 112 / 14
n = 8
Molecular formula = n (empirical formula)
Molecular formula = 8 (CH₂)
Molecular formula = C₈H₁₆
What happens when molten material travels along the underside of the crust?
Answers
Answer:
Explanation:
The earth is comprised of denser materials such as iron and nickel and other siderophile elements in the core and silicate materials in the mantle. The temperature at the core of the earth is extremely high that generates a force, that allows the molten materials (magma) to rise up from the bottom of the mantle towards the crust, in the form of convection currents. This upward movement of magma forces the lithospheric plates to move.
Thus, magma rises from the bottom of the mantle towards the crust.

Answers
Answer:
Hydrogen bond strengths range from 4 kJ to 50 kJ per mole of hydrogen bonds. In molecules containing N-H, O-H or F-H bonds, the large difference in electronegativity between the H atom and the N, O or F atom leads to a highly polar covalent bond (i.e., a bond dipole).

What is the value for AG at 100 Kif AH = 27 kJ/mol and AS = 0.09 kJ/(mol-K)?
A. AG = 2700 kJ/mol
B. AG = -36 kJ/mol
C. AG = 0 kJ/mol
D. AG = 18 kJ/mol
Answers
Answer:
ΔG = 18KJ/mol
Explanation:
Given data:
ΔS = 0.09 Kj/mol.K
ΔH = 27 KJ/mol
Temperature = 100 K
ΔG = ?
Solution:
Formula:
ΔG = ΔH - TΔS
ΔS = entropy
ΔH = enthalpy
by putting values,
ΔG = 27 KJ/mol - 100K(0.09 Kj/mol.K)
ΔG = 27 KJ/mol - 9 KJ/mol
ΔG = 18KJ/mol
Answer:
ΔG = 18kJ/mol

Methane(CH4) is a gas at room temperature, Methanol (CH3OH) is a liquid. Explain why using types of intermolecular forces present.
Answers
Explanation:
Methane is a gas at room temperature but methanol is a liquid because in methane there's London dispersion intermolecular force but in methanol there's H-bond and London dispersion force. H-bond is more stronger than London dispersion force. So, it increases the boiling point of methanol that's why methane is gas at room temperature due to weak attraction of London dispersion force and methanol is liquid.
Methanol has a higher boiling point than methane due to stronger intermolecular forces (IMFs), or attraction between individual molecules. This makes its molecules more difficult to separate, requiring more energy and resulting in a higher boiling point.
What are intermolecular forces?An intermolecular force is a force that mediates the interaction of molecules, including electromagnetic forces of attraction or repulsion that act between atoms and other types of neighboring particles, such as atoms or ions.
Intermolecular forces are classified into five types namely,
Ion-dipole forces.Ion-induced dipole forces.Dipole-dipole forces.Dipole-induced dipole forces.Induced dipole forces.Between ions and polar dipole molecules, ion-dipole forces exist.
Since of stronger intermolecular forces (IMFs), or attraction between individual molecules, methanol has a higher boiling point than methane.
This makes it more difficult to separate its molecules, requiring more energy and resulting in a higher boiling point.
Thus, this is the reason of using types of intermolecular forces present.
