Answer:

[CO2] > [N2] > [He]

Explanation:

The relative concentration of CO2, N2 and He depends on the solubility of each gas in water. The more soluble in water a gas is, the greater its concentration in aqueous solution.

Among the gases listed, CO2 is most soluble in water hence it is expected to have the greatest concentration in solution followed by N2. Helium gas is insoluble in water hence it has the least concentration in the aqueous solution.

Rzqust [24]

Answer:

The balanced reaction in the acidic medium is:

2MnO4^-+3CN^-+2H^+\rightarrow 2MnO_2+H_2O+3CNO^-

Explanation:

CN^- + MnO4^-\rightarrow CNO^- + MnO_2

1) CN^-\rightarrow CNO^- ( oxidation)

Balance oxygen by adding water :

CN^-+H_2O\rightarrow CNO^-

Now , balance hydrogen by adding hydrogen ions on the side where hydrogen are less.

CN^-+H_2O\rightarrow CNO^-+2H^+

Add electrons to balance charge where positive charge is more.

CN^-+H_2O\rightarrow CNO^-+2H^++2e^-..[1]

2) MnO4^-\rightarrow MnO_2 (reduction)

Balance oxygen by adding water :

MnO4^-\rightarrow MnO_2+2H_2O

Now , balance hydrogen by adding hydrogen ions by adding them on the side where hydrogen are less.

MnO4^-+4H^+\rightarrow MnO_2+2H_2O..[2]

Add electrons to balance charge where positive charge is more.

MnO4^-+4H^++3e^-\rightarrow MnO_2+2H_2O..[2]

3 × [1] + 2 × [2]

The balanced reaction in the acidic medium is:

2MnO4^-+3CN^-+2H^+\rightarrow 2MnO_2+H_2O+3CNO^-

Consider the reaction. Upper H subscript 2 upper o (g) plus upper C l subscript 2 upper O (g) double-headed arrow 2 upper H uppe
dedylja [7]

Answer:

Equilibrium constant for the reaction is 0.0892

Explanation:

This is the reaction of equilibrium

         H₂O      +     Cl₂O     ⇄    2HClO

Eq   0.077M       0.077M           0.023M

Let's make the expression for Kc

Kc = [HClO]² / [Cl₂O] . [H₂O]

Kc= 0.023² / 0.077 . 0.077 = 0.0892
