प्रश्न
Write a balanced reaction for the following conversions (A, B, C, D)
\[\ce{Fe→[A]FeCl2 →[B]FeCO3→[C]Fe(NO3)2→[D]Fe(OH)2}\]

उत्तर
A = HCl
B = Na2CO3
C = HNO3
D = NaOH
A : \[\ce{Fe + 2HCl → FeCl2 + H2}\]
B : \[\ce{FeCl2 + Na2O3→ FeCO3 + 2NaCl}\]
C : \[\ce{FeCO3 + 2HNO3 → Fe (NO3)2 + H2O + CO2}\]
D : \[\ce{Fe(NO3)2 + 2NaOH → Fe(OH)2 + 2NaNO3}\]
