<u>Answer:</u>

(a): The expression of equilibrium constant is K_{eq}=\frac{[NO]^2}{[N_2][O_2]}

(b): The equation to solve the concentration of NO is [NO]=\sqrt{K_{eq}\times [N_2]\times [O_2]}

(c): The concentration of NO is 0.0017 M.

<u>Explanation:</u>

The equilibrium constant is defined as the ratio of the concentration of products to the concentration of reactants raised to the power of the stoichiometric coefficient of each. It is represented by the term K_{eq}

(a):

The given chemical equation follows:

N_2+O_2\rightarrow 2NO

The expression for equilbrium constant will be:

K_{eq}=\frac{[NO]^2}{[N_2][O_2]}

(b):

The equation to solve the concentration of NO follows:

[NO]=\sqrt{K_{eq}\times [N_2]\times [O_2]}            ......(1)

(c):

Given values:

K_{eq}=1.2\times 10^{-4}

[N_2]_{eq}=0.166M

[O_2]_{eq}=0.145M

Plugging values in equation 1, we get:

[NO]=\sqrt{(1.2\times 10^{-4})\times 0.166\times 0.145}

[NO]=\sqrt{2.88\times 10^{-6}}

[NO]=0.0017 M

Hence, the concentration of NO is 0.0017 M.

Complete the charge balance equation for an aqueous solution of h2co3 that ionizes to hco−3 and co2−3.
Zielflug [23.3K]

The charge balance equation for an aqueous solution of H₂CO₃ that ionizes to HCO₃⁻ and CO₃⁻² is [HCO₃⁻] =  2[CO₃⁻²] + [H⁺] + [OH⁻]

<h3>What is Balanced Chemical Equation ?</h3>

The balanced chemical equation is the equation in which the number of atoms on the reactant side is equal to the number of atoms on the product side in an equation.

The equation for aqueous solution of H₂CO₃ is

H₂CO₃ → H₂O + CO₂

The charge balance equation is

[HCO₃⁻] =  2[CO₃⁻²] + [H⁺] + [OH⁻]

Thus from the above conclusion we can say that The charge balance equation for an aqueous solution of H₂CO₃ that ionizes to HCO₃⁻ and CO₃⁻² is [HCO₃⁻] =  2[CO₃⁻²] + [H⁺] + [OH⁻]
