Which molecule will undergo only london dispersion forces when interacting with other molecules of the same kind?.
Neko [114]

Molecules undergo London dispersion forces:

C_{4}H_{10} 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).

NOTE: Your question is incomplete, but most probably your full question was, which molecule will undergo only London dispersion forces when interacting with other molecules of the same kind? Which molecule will undergo only London dispersion forces when interacting with other molecules of the same kind?

A. C_{4}H_{10}

B. NaC_{2}H_{3}O_{2}

C. CH_{2}C_{12}

D. C_{2}H_{5}OH HF

A sample of n2 occupies 3. 0l at 3. 0atm. What volume will it occupy when the pressure is changed to 0. 5atm and the temperature
belka [17]

It will occupy 18 L volume when the pressure is changed to 0. 5 atm and the temperature remain constant.

Calculation,

According to Boyle law, the pressure of a given quantity of gas varies inversely with its volume at constant temperature.

P_{1} V _{1} = k    .....(i)

  • P_{1} is initial pressure = 3 atm
  • V _{1} is initial volume = 3L
  • k is constant

P_{2} V _{2} = k    (ii)

  • P_{2} is final pressure = ?
  • V _{2} is final volume = 0.5atm
  • k is constant

Combining equation (i) and (ii). we get,

P_{1} V _{1}  = P_{2} V _{2}

3 atm× 3L=  V _{2}× 0.5atm

V _{2}  =   3 atm× 3L/0.5atm = 18 L

Boyle law used during respiration or breathing.

A 1.56 g sample of copper reacts with a mass of oxygen to form 1.95 g of the metal oxide. In another experiment, the molar mass
vitfil [10]

Answer:

The molecular formula of the metal oxide is CuO

Explanation:

Molar mass 79.545 g/m belongs to CuO

This is the reaction:

2Cu(s) + O₂(g) → 2CuO (s)

2 mol of Cu produce 2 mol of CuO

Molar mass Cu = 63.5 g/m

Mass / Molar mass = 1.56 g / 63.5 g/m →0.0245 m

0.0245 mol of Cu produce 0.0245 mole of CuO

Molar mass CuO = 79.545 g/m

Mol . Molar mass = mass

0.0245 m . 79.545 g/m = 1.95 g

Identify ammonia. a. strong electrolyte, strong base b. weak electrolyte, strong base c. strong electrolyte, weak base d. nonele
dedylja [7]

Answer:

Ammonia is a weak electrolyte, weak base.

Option e.

Explanation:

Ammonia can take a proton from water to make ammonium.

It is a base, because it takes proton.

When a compound can take protons, we know that is base, according to Bronsted Lowry theory.

We can't describe ammonia as a base, according to Arrhenius, but we know it is base according to Lewis, because the N from the ammonia can be a donor of its electron pair.

It is weak because an small amount of ammonia, can react to produce ammonium, between the protons of water. This is the equilibrium, where the ammonia is considered as the conjugate strong acid of ammonia.

NH₃ +  H₂O  ⇄  NH₄⁺  +  OH⁻     Kb

All the amines are considered as weak bases, because they look like ammonia, where the H of NH₃ are replaced by others chains.

------NH₂

-----NH-----
