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^-

if kept at a constant temperature, what is the concentration at 865s if the initial concentration was 0.0225M
Anestetic [448]

Answer:

[SO_2Cl_2]=0.0175M

Explanation:

Hello!

In this case, considering that the decomposition reaction of SO2Cl2 is first-order, we can write the rate law shown below:

r=-k[SO_2Cl_2]

We also consider that the integrated rate law has been already reported as:

[SO_2Cl_2]=[SO_2Cl_2]_0exp(-kt)

Thus, by plugging in the initial concentration, rate constant and elapsed time we obtain:

[SO_2Cl_2]=0.0225Mexp(-2.90x10^{-4}s^{-1}*865s)

[SO_2Cl_2]=0.0175M

Best regards!

When the pressure that a gas exerts
Ronch [10]

Answer:

The pressure changes from 2.13 atm to 1.80 atm.

Explanation:

Given data:

Initial pressure = ?

Final pressure = 1.80 atm

Initial temperature = 86.0°C (86.0 + 273 = 359 K)

Final temperature = 30.0°C (30+273 =303 K)

Solution:

According to Gay-Lussac Law,

The pressure of given amount of a gas is directly proportional to its temperature at constant volume and number of moles.

Mathematical relationship:

P₁/T₁ = P₂/T₂

Now we will put the values in formula:

P₁ = P₂T₁ /T₂

P₁ = 1.80 atm × 359 K / 303 K

P₁ = 646.2 atm. K /303 K

P₁ = 2.13 atm

The pressure changes from 2.13 atm to 1.80 atm.
