Explanation:

Step1: Analyze reaction 1

Silver (Ag) is less reactive than potassium (K) in the activity series. So, no reaction occurs.

$$Ag + KNO_3 ightarrow NR$$

Step2: Analyze reaction 2

Zinc (Zn) is more reactive than silver (Ag). The reaction is a single - replacement reaction.

$$Zn+2AgNO_3 ightarrow Zn(NO_3)_2 + 2Ag$$

Step3: Analyze reaction 3

Aluminium (Al) reacts with sulfuric acid ($H_2SO_4$). The balanced equation is:

$$2Al + 3H_2SO_4 ightarrow Al_2(SO_4)_3+3H_2$$

Step4: Analyze reaction 4

Chlorine ($Cl_2$) is more reactive than iodine (I). The reaction is:

$$Cl_2 + 2KI ightarrow 2KCl+I_2$$

Step5: Analyze reaction 5

Lithium (Li) reacts with water ($H_2O$). The balanced equation is:

$$2Li + 2H_2O ightarrow 2LiOH + H_2$$

Step6: Analyze reaction 6

Copper (Cu) is less reactive than iron (Fe). So, no reaction occurs.

$$Cu + FeSO_4 ightarrow NR$$

Step7: Analyze reaction 7

Sodium (Na) reacts with water ($H_2O$). The balanced equation is:

$$2Na+2H_2O ightarrow 2NaOH + H_2$$

Step8: Analyze reaction 8

Iron (Fe) is more reactive than lead (Pb). The reaction is:

$$Fe+Pb(NO_3)_2 ightarrow Fe(NO_3)_2 + Pb$$

Step9: Analyze reaction 9

Copper (Cu) is less reactive than hydrogen (H) in the context of this reaction. So, no reaction occurs.

$$Cu + H_2O ightarrow NR$$

Step10: Analyze reaction 10

Copper (Cu) is less reactive than aluminium (Al). So, no reaction occurs.

$$Cu+Al_2(SO_4)_3 ightarrow NR$$
