Which series of reactions correctly represents chemical rections related to iron and its compounds ?

Options

A. `Na+O_(2) to Na_(2)O overset(HCl(aq))to NaCl overset(CO_(2))to Na_(2)CO_(3) overset(Delta)toNa`
B. `Na overset(O_(2)) to Na_(2)O overset(H_(2)O)to NaOH overset(CO_(2)) to Na_2CO_(3) overset(Delta)Na`
C. `Na+H_(2)O to NaOH overset(HCl) to NaCl overset(CO_(2))toNa_(2)CO_(3) overset(Delta)to Na`
D. `Na+H_(2)O to NaOH overset(CO_(2))to Na_(2)CO_(3) overset(HCl) to underset("(Molten)")(NaCl)overset("electrolysis")toNa`

Answer

D

Explanation

`2Na+2H_2O to 2NaOH +H_(2) uarr`
`2NaOH +CO_(2) to Na_(2)CO_(3) +H_(2)O`
`Na_(2)CO_(3) +2HCl to 2NaCl +H_(2)O +CO_(2)`
`underset("(Molten)")(NaCl) overset("Electrolysis")to underset(Na)underset(" "darr+e^(-))(Na^(+))+ underset(Cl)underset(darr-e^(-))(Cl^(-))`
