Marks: +1, -0
Give balanced chemical equations for the following conversions A,BA, B and C :
Fe→AFeCl3→B\mathrm{Fe} \xrightarrow[]{A}\mathrm{FeCl}_3 \xrightarrow[]{B} FeCO3→CFe(NO3)2\mathrm{FeCO}_3 \xrightarrow[]{C}\mathrm{Fe}(\mathrm{NO}_3)_2
Solution:  
   A:       2Fe+3Cl2→  2FeCl3\; \text{ A: }\; \;\; 2\mathrm{Fe}+3\mathrm{Cl}_2 \rightarrow\;2\mathrm{FeCl}_3
B:2FeCl3+3Na2CO3→  Fe2(CO3)3+\text{B}: 2\mathrm{FeCl}_3+3\mathrm{Na}_2\mathrm{CO}_3 \rightarrow\; \mathrm{Fe}_2(\mathrm{CO}_3)_3+   6NaCl\;6\mathrm{NaCl}
C:FeCO3+2HNO3→  Fe(NO3)2+\text{C}: \mathrm{FeCO}_3+2\mathrm{HNO}_3 \rightarrow\; \mathrm{Fe}(\mathrm{NO}_3)_2+   H2O+CO2↑\; \mathrm{H}_2\mathrm{O}+ \mathrm{CO}_2 \uparrow
