1.	NaBr, used to produce AgBr for use in photography can itself be prepared as follows: Fe+Br2→FeBr2 FeBr2+Br2→Fe3Br8 (not balanced) Fe3Br8+Na2CO3→NaBr+CO2+Fe3O4 (not balanced) How much Fe, in kg, is consumed to produce 4.12×103 kg NaBr
Answer» $N a B r$ , used to produce $A g B r$ for use in photography can itself be prepared as follows: $F e + B r_{2} \to F e B r_{2}$ $F e B r_{2} + B r_{2} \to F e_{3} B r_{8}$ (not balanced) $F e_{3} B r_{8} + N a_{2} C O_{3} \to N a B r + C O_{2} + F e_{3} O_{4}$ (not balanced) How much $F e$ , in kg, is consumed to produce $4.12 \times 10^{3} k g N a B r$
