The magnetic moment of a transition metal ion is found to be 3.87 Bohr Magneton (BM). The number of — d and f Block Elements Chemistry Question

💡 Solution & Explanation

Step 1: When silver halides are fused with sodium carbonate, they undergo a displacement reaction that initially produces silver carbonate. Step 2: At the high temperatures of fusion, silver carbonate is highly unstable and decomposes to silver oxide, which further decomposes to metallic silver (Ag) and oxygen. Step 3: The overall reaction is: 4AgCl + 2Na2CO3 ---> 4NaCl + 2CO2 + O2 + 4Ag. Hence, metallic silver (Ag) is formed, matching option (c).
