True [87]3 years ago

Answer:

A. N₂O₅ is produced at 0.2 mol·L⁻¹s⁻¹, and O₂ is produced at 0.05 mol·L⁻¹s⁻¹.  

Explanation:

2N₂O₅ ⟶ 4NO₂ + O₂

For every two molecules of N₂O₅ that disappear, we get four molecules of NO₂ and one of O₂.

NO₂ is forming twice as fast, and O₂ is forming half as fast, as N₂O₅ is decomposing.

N₂O₅ is decomposing at a rate of 0.1 mol·L⁻¹s⁻¹.

So, N₂O₅ is produced at 0.2 mol·L⁻¹s⁻¹, and O₂ is produced at 0.05 mol·L⁻¹s⁻¹.

lidiya [134]

<u>Answer:</u> Copper (I) iodide will precipitate first.

<u>Explanation:</u>

We are given:

K_{sp} of CuCl = 1.0\times 10^{-6}

K_{sp} of CuI = 5.1\times 10^{-12}

Concentration of Cl^-\text{ ion}=0.021M

Concentration of I^-\text{ ion}=0.017M

Solubility product is defined as the product of concentration of ions present in a solution each raised to the power its stoichiometric ratio.

  • <u>For CuCl:</u>

K_{sp}=[Cu^+][Cl^-]

Putting values in above equation, we get:

1.0\times 10^{-6}=[Cu^+]\times 0.021

[Cu^+]=\frac{1.0\times 10^{-6}}{0.021}=4.76\times 10^{-5}M

Concentration of copper (I) ion = 4.76\times 10^{-5}M

  • <u>For CuI:</u>

K_{sp}=[Cu^+][I^-]

Putting values in above equation, we get:

5.1\times 10^{-12}=[Cu^+]\times 0.017

[Cu^+]=\frac{5.1\times 10^{-12}}{0.017}=3.00\times 10^{-10}M

Concentration of copper (I) ion = 3.00\times 10^{-10}M

For the precipitation of copper (I) ions, we need less concentration of copper (I) ions. So, copper (I) iodide will precipitate first.
