Identify the thermal decomposition reactions that are also correctly classified as redox reactions: — Redox Reactions and Volumetric Analysis Chemistry Question

💡 Solution & Explanation

A decomposition reaction is a redox reaction if at least one product is in an elemental state, or if O.S. changes occur. In A, H and O change to 0. In C, Cl and O change. In D, N (+5 to +4) and O (-2 to 0) change. In B, Ca (+2), C (+4), and O (-2) remain unchanged (Non-redox).
