<u>Answer:</u> The decreasing order of K_{sp} is AgSCN>AgBr>AgCN

<u>Explanation:</u>

  • <u>For AgBr:</u>

The balanced equilibrium reaction for the ionization of silver bromide follows:

AgBr\rightleftharpoons Ag^{+}+Br^-

                 s      s

The expression for solubility constant for this reaction will be:

K_{sp}=[Ag^{+}][Br^-]

We are given:

s=7.3\times 10^{-7}mol/L

Putting values in above equation, we get:

K_{sp}=s\times s\\\\K_{sp}=s^2\\\\K_{sp}=(7.3\times 10{-7})^2=5.33\times 10^{-13}

Solubility product of AgBr = 5.33\times 10^{-13}

  • <u>For AgCN:</u>

The balanced equilibrium reaction for the ionization of silver cyanide follows:

AgCN\rightleftharpoons Ag^{+}+CN^-

                    s      s

The expression for solubility constant for this reaction will be:

K_{sp}=[Ag^{+}][CN^-]

We are given:

s=7.7\times 10^{-9}mol/L

Putting values in above equation, we get:

K_{sp}=s\times s\\\\K_{sp}=s^2\\\\K_{sp}=(7.7\times 10{-9})^2=5.93\times 10^{-17}

Solubility product of AgCN = 5.33\times 10^{-17}

  • <u>For AgSCN:</u>

The balanced equilibrium reaction for the ionization of silver thiocyanate follows:

AgSCN\rightleftharpoons Ag^{+}+SCN^-

                     s      s

The expression for solubility constant for this reaction will be:

K_{sp}=[Ag^{+}][SCN^-]

We are given:

s=1.0\times 10^{-6}mol/L

Putting values in above equation, we get:

K_{sp}=s\times s\\\\K_{sp}=s^2\\\\K_{sp}=(1.0\times 10{-6})^2=1.0\times 10^{-12}

Solubility product of AgSCN = 1.0\times 10^{-12}

The decreasing order of K_{sp} follows:

AgSCN>AgBr>AgCN

Answer:

The ozone layer

Explanation:

It sort of acts like a defense from the harmful ones and only allows weaker and non threatening ones in the atmosphere. If global warming continues, the ozone layer will break and we will be exposed to them
