Answer:

A. It is the ratio of the concentrations of products to the concentrations of reactants.

Explanation:

The equilibrium constant of a chemical reaction is the ratio of the concentration of products to the concentration of reactants.

This equilibrium constant can be expressed in many different formats.

For any system, the molar concentration of all the species on the right side are related to the molar concentrations of those on the left side by the equilibrium constant.
The equilibrium constant is a constant at a given temperature and it is temperature dependent.
The derivation of the equilibrium constant is based on the law of mass action.
It states that "the rate of a chemical reaction is proportional to the product of the concentration of the reacting substances. "

Aliun [14]

Answer:

Explanation:

During that process of being exposed to air and water while being left outside or in the elements for an extended period of time, a variety of different types of rusts can form, but the most common form is Fe2O3. Rust only forms on the outside of a metal surface because it requires exposure of oxygen and water to rust.

Answer: Cl2

Explanation: ionic compounds forms cations and anions in water solution.

HI is a weak acid and forms H+ and I- ions. Cl2 is dissolved slightly in water

And stays in molecule form which can not transfer charge like cations and anions.

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.
