Answer:

Answer:

Kc = 0.20

Explanation:

N₂O₄ ⇄ 2NO₂

moles 5.3mol 2.3mol

Vol 5L 5L

Molarity 5.3/5M 2.3/5M

= 1.06M = 0.46M

Kc = [NO₂]²/[N₂O₄] = (0.46)²/(1.06) = 0.1996 ≅ 0.20

We have learned that the Lewis model portrays a chemical bond as the transfer or sharing of electrons represented as dots. Valen

photoshop1234 [79]

Answer:

According to molecular orbital theory, chemical bond occurs as electrons are able to reduce their energy by entering the resulting molecular orbitals.

Chemical bonds are not located among atoms, they are distributed all over the molecule.

Uses test methods to solve the equation of Schrodinger.

You can never do better than nature, however strong your assumption is. Calculations of minimum energy must be done by software.

The enthalpy of combustion for octane (C8H18(l)), a key component of gasoline, is -5,074 kJ/mol. This value is the Delta. Hrxn f

Inessa [10]

Combustion can be defined as the reaction of a compound with oxygen. The enthalpy of combustion of octane is $\Delta H_{\rm rxn}$ for $\rm C_8H_{18}\;+\;25\;O_2\;\rightarrow 8\;CO_2\;+\;9\;H_2O$ .

<h3>What is the enthalpy of reaction?</h3>

The enthalpy of reaction is the amount of heat energy absorbed or lost by the molecules in the chemical reaction.

The enthalpy of combustion is the amount of heat energy released by the compound in the reaction with oxygen.

The reaction in which heat is liberated with the reaction of a compound with oxygen has an enthalpy of combustion, equivalent to the enthalpy of reaction.

The combustion of octane can be given as:

$\rm C_8H_{18}\;+\;25\;O_2\;\rightarrow 8\;CO_2\;+\;9\;H_2O$

Thus, the reaction has combustion energy equivalent to the enthalpy of the reaction is $\rm C_8H_{18}\;+\;25\;O_2\;\rightarrow 8\;CO_2\;+\;9\;H_2O$ . Thus, option B is correct.
