The substance whose Lewis structure shows three covalent bonds is Nitrogen gas molecule.

<h3>What is Lewis structure?</h3>

Lewis structure is a dot structure which gives idea about the number of valence electrons that are involved in the bonding within the molecule.

Lewis dot structure of nitrogen gas will be expressed as in the attached image, where between two nitrogen atoms triple bond is present. That triple bond is formed by the sharing of electrons and known as covalent bonds.

Hence in nitrogen gas molecule three covalent bonds is present.

Temka [501]

Rate of production of NO₂ = 0.2 M/s

Rate of production of O₂ = 0.05 M/s

<h3>Further explanation</h3>

Given

The rate of N₂O₅ : 0.1 M/s

Reaction

2N₂O₅⇒4NO₂+O₂

Required

The rate of production of NO₂ and O₂ at the same time point

Solution

Rate of disappearance of N₂O₅ = reaction rate x coefficient of N₂O₅

0.1 M/s=reaction rate x 2

<em>reaction rate = 0.05 M/s</em>

The rate of production of NO₂=

Rate of production of NO₂ = reaction rate x coefficient of NO₂

Rate of production of NO₂ = 0.05 M/s x 4

Rate of production of NO₂ = 0.2 M/s

The rate of production of O₂=

Rate of production of O₂ = reaction rate x coefficient of O₂

Rate of production of O₂ = 0.05 M/s x 1

Rate of production of O₂ = 0.05 M/s

mylen [45]

The sample of oxygen gas was collected through water displacement. So, the gas collected will be a mixture of oxygen and water vapor.

Given that the total pressure of the mixture of gases containing oxygen and water vapor = 749 Torr

Vapor pressure of pure water at $26.4^{0}C$ =25.81mmHg

= $25.81 mmHg*\frac{1 Torr}{1 mmHg} =25.81 Torr$

According to Dalton's law of partial pressures,

Total pressure = Partial pressure of Oxygen gas + Partial pressure of water

749 Torr = Partial pressure of Oxygen gas + 25.81 Torr

Partial pressure of Oxygen gas = 749 Torr - 25.81 Torr = 723.19 Torr

Therefore the partial pressure of Oxygen gas in the mixture collected will be 723.19 Torr

Which of the following statements is not correct?

Pavlova-9 [17]

Answer: This option is incorrect: <span>B. Covalent compounds are held together by much stronger interparticle forces than are ionic compounds.

Justification:

Ionic bonds, held by ionic compounds, are much stronger than covalent bonds, held by covalent compounds.

In ionic bonds one element yields one or more electrons forming a cation (a positively charged ion) and the other element accepts the electrons forming an anion (a negatively charged ion).

The anion and the cation are electrostatically atracted by each other. This electrostatic atraction force, named ionic bond, is very strong.

As result of this, the ionic compounds form strong crystals with high boiling and fusion points. A good example of this the sodium chloride, formed by the union of cation Na(+) and anion Cl(-).

The covalent bonds are result of sharing electrons and do not form ions. This bond is weaker than the ionic bond.
