1. ag + kno₃ →
2. zn + agno₃ →
3. al + h₂so₄ →
4. cl₂ + ki →
5. li + h₂o →
6. cu + feso₄ →
7. na + h₂o →
8. fe + pb(no₃)₂ →
9. cu + h₂o →
10. cu + al₂(so₄) →
11. al + pb(no₃)₂ →

Explanation:

Step1: Check Activity Series

According to the activity series, a more reactive metal can displace a less reactive metal from its compound. Silver (\(Ag\)) is less reactive than potassium (\(K\)). So, \(Ag + KNO_3\) will not react.

Step2: Write the Reaction

For \(Zn+AgNO_3\), zinc (\(Zn\)) is more reactive than silver (\(Ag\)). The reaction is \(Zn + 2AgNO_3=Zn(NO_3)_2 + 2Ag\).

Step3: Balance the Equation

For \(Al + H_2SO_4\), the reaction is \(2Al+3H_2SO_4 = Al_2(SO_4)_3+3H_2\).

Step4: Analyze \(Cl_2+KI\)

Chlorine (\(Cl_2\)) is more reactive than iodine (\(I\)). The reaction is \(Cl_2 + 2KI=2KCl+I_2\).

Step5: Consider \(Li + H_2O\)

Lithium (\(Li\)) reacts with water to form lithium hydroxide and hydrogen. The reaction is \(2Li + 2H_2O=2LiOH + H_2\).

Step6: Examine \(Cu + FeSO_4\)

Copper (\(Cu\)) is less reactive than iron (\(Fe\)). So, \(Cu + FeSO_4\) will not react.

Step7: Look at \(Na + H_2O\)

Sodium (\(Na\)) reacts vigorously with water. The reaction is \(2Na+2H_2O = 2NaOH+H_2\).

Step8: Check \(Fe + Pb(NO_3)_2\)

Iron (\(Fe\)) is more reactive than lead (\(Pb\)). The reaction is \(Fe + Pb(NO_3)_2=Fe(NO_3)_2+Pb\).

Step9: Analyze \(Cu + H_2O\)

Copper (\(Cu\)) does not react with water under normal conditions. So, \(Cu + H_2O\) will not react.

Step10: Examine \(Cu + Al_2(SO_4)_3\)

Copper (\(Cu\)) is less reactive than aluminium (\(Al\)). So, \(Cu + Al_2(SO_4)_3\) will not react.

Step11: Consider \(Al + Pb(NO_3)_2\)

Aluminium (\(Al\)) is more reactive than lead (\(Pb\)). The reaction is \(2Al + 3Pb(NO_3)_2=2Al(NO_3)_3+3Pb\).

Answer:

1. \(Ag + KNO_3

ightarrow NR\)

1. \(Zn + 2AgNO_3=Zn(NO_3)_2 + 2Ag\)
2. \(2Al+3H_2SO_4 = Al_2(SO_4)_3+3H_2\)
3. \(Cl_2 + 2KI=2KCl+I_2\)
4. \(2Li + 2H_2O=2LiOH + H_2\)
5. \(Cu + FeSO_4

ightarrow NR\)

1. \(2Na+2H_2O = 2NaOH+H_2\)
2. \(Fe + Pb(NO_3)_2=Fe(NO_3)_2+Pb\)
3. \(Cu + H_2O

ightarrow NR\)

1. \(Cu + Al_2(SO_4)_3

ightarrow NR\)

1. \(2Al + 3Pb(NO_3)_2=2Al(NO_3)_3+3Pb\)
