Answer:
A) 3.17 g of Zn
Explanation:
Let's consider the reduction of Zn(II) that occurs in an electrolysis bath.
Zn⁺²(aq) + 2e⁻ → Zn(s)
We can establish the following relations:
- 1 min = 60 s
- 1 A = 1 C/s
- The charge of 1 mole of electrons is 96,468 C (Faraday's constant).
- When 2 moles of electrons circulate, 1 mole of Zn is deposited.
- The molar mass of Zn is 65.38 g/mol
The mass of Zn deposited under these conditions is:
Answer:
Explanation:using the ideal gas formula, calculate the volume of 1.5omoles of a gas at 115kPA and a temperature of 298k?
Answer choice C. Reduction has its electrons as a reactant.
Molecules undergo London dispersion forces:
is the molecule will undergo only London dispersion forces when interacting with other molecules of the same kind.
What are London dispersion forces?
- A sort of force that interacts between atoms and molecules that is often electrically symmetric is referred to as a London dispersion force.
- When viewed from the nucleus, their electron distribution is frequently symmetrical. This dispersion force, which is also known as a transient attractive force, is frequently observed when the locations of the electrons in two nearby atoms cause the atoms to temporarily form dipoles.
- The bond is polar when there are significant variations between the elements' electronegativities; it is nonpolar when there are similarities. When the molecule's dipole moment is equal to O, it is nonpolar; when it differs from O, it is polar.
- The force at these molecules is known as the London dispersion force. In nonpolar molecules, the forces are weak, and partial charges must be induced so that they can bond. In polar molecules, partial charges caused by polarity result in a stronger link known as a dipole-dipole. The dipole-dipole is significantly stronger and known as a hydrogen bond if it is connected to a large electronegative atom (F, O, or N). Ionic force is the name for the attraction force at ionic substances.
- The intermolecular force in the letter an is the London dispersion force because the compound is nonpolar;
<u>Reason for incorrect options:</u>
b: the compound is ionic because Na is a metal and the other part is covalent,
c: two compounds are possible: one is nonpolar and exhibits London dispersion force; the other is polar and exhibits dipole-dipole force; and
d: both compounds exhibit hydrogen bonds (H bonded to O, and H bonded to F).
