Answer

B. 2AgNO_{3} + Cu \rightarrow Cu(NO_{3})_{2} + 2Ag Explanation 1. Identify reaction type Copper displaces silver from silver nitrate: 2AgNO_{3} + Cu \rightarrow Cu(NO_{3})_{2} + 2Ag. Single displacement reaction. 2. Check atom balance LHS: Ag=2, Cu=1, NO₃=2; RHS: Ag=2, Cu=1, NO₃=2 → Balanced.

Explanation

1. Identify reaction type <br /> Copper displaces silver from silver nitrate: $2AgNO_{3} + Cu \rightarrow Cu(NO_{3})_{2} + 2Ag$. Single displacement reaction. <br />2. Check atom balance <br /> LHS: Ag=2, Cu=1, NO₃=2; RHS: Ag=2, Cu=1, NO₃=2 → Balanced.
