Na2CO3 + Fe2O3 A + CO2 what is A in the reaction? — d and f Block Elements Chemistry Question

💡 Solution & Explanation

Step 1: Heating sodium carbonate (Na2CO3) with iron(III) oxide (Fe2O3) at high temperatures leads to a solid-state reaction with the evolution of carbon dioxide gas. Step 2: The balanced chemical equation is: Na2CO3 + Fe2O3 --Δ--> 2NaFeO2 + CO2. Step 3: The product A is sodium ferrite (NaFeO2), which corresponds to option (a).
