Answer:

Concentration of dissolved nitrogen = 5.2 × 10⁻⁴ mol/L

Explanation:

More the pressure of the gas, more will be its solubility.

So, for two different pressure, the relation between them is shown below as:-

\frac {P_1}{C_1}=\frac {P_2}{C_2}

Given ,  

P₁ = 1 atm

P₂ = 0.76 atm

C₁ = 6.8 × 10⁻⁴ mol/L

C₂ = ?

Using above equation as:

\frac{1\ atm}{6.8\times 10^{-4}\ mol/L}=\frac{0.76\ atm}{C_2}

C_2=\frac{0.76\times 6.8\times 10^{-4}}{1}\ mol/L

<u>Concentration of dissolved nitrogen = 5.2 × 10⁻⁴ mol/L</u>

Fill in the left side of this equilibrium constant equation for the reaction of nitrous acid (HNO_2) with water.
mafiozo [28]

Answer:

Ka=\frac{[H^+][NO_2^-]}{[HNO_2]}

Explanation:

The reaction

The reaction of nitrous acid with water is a dissociation reaction of an acid:

HNO_2(aq) + H_2O(l) \longrightarrow H^+(aq) + NO_2^-(aq) + H_2O(l)

HNO_2(aq) \longrightarrow H^+(aq) + NO_2^-(aq)

The Ka equation

Ka=\frac{[H^+][NO_2^-]}{[HNO_2]}

From the atomic clock that utilizes C-133 which has an approximate frequency of 9.193 x 109 Hz. The wavelength of the energy is calculated to be 0.0326m.

From the given information:

  • The frequency f = 9.193 × 10⁹ Hz = 9.193 × 10⁹ 1/s
  • The wave speed c = 3.00 × 10⁸ m/s

Recall that:

The wavelength is the spatial successive distance between two crests of a wave and can be expressed by the formula:

\mathbf{\lambda = \dfrac{c}{f}}

\mathbf{\lambda = \dfrac{3.00 \times 10^8 \ m/s }{9.193 \times 10^9 \  1/s}}

\mathbf{\lambda =0.0326  \ m}

Therefore, we can conclude that the wavelength of the atomic clock is 0.0326m. As such Option D is correct.
