Answer

Answer:

2AgNO₃ + Cu → Cu(NO₃)₂ + 2Ag

Explanation:

Step1: Analyze the first reaction

NaOH + HCl → NaCl + H₂O is a double - replacement reaction (acid - base neutralization).

Step2: Analyze the second reaction

4Fe(OH)₂ + O₂ → 4Fe(OH)₃ is a combination reaction.

Step3: Analyze the third reaction

CO₂ → C + O₂ is a decomposition reaction.

Step4: Analyze the fourth reaction

2AgNO₃ + Cu → Cu(NO₃)₂ + 2Ag: In a single - replacement reaction, one element replaces another in a compound. Here, Cu (a metal) replaces Ag (a metal) in AgNO₃. The general form of a single - replacement reaction is (A+BC\rightarrow AC + B) (where (A) and (B) are metals or (A) is a non - metal and (B) is a non - metal). In (2AgNO₃+Cu\rightarrow Cu(NO₃)₂ + 2Ag), (A = Cu), (B = Ag), and (BC=AgNO₃), (AC = Cu(NO₃)₂).
