B. `Naoverset(O_2) rarr Na_(2)O overset(H_2O)rarr NaOH overset(CO_2) rarr Na_(2)CO_(3) overset(Delta) rarr Na`
C. `Na+H_(2)O rarr NaOH overset(HCl) rarr NaCl overset(CO_2)rarr Na_(2)CO_(3) overset(Delta) rarr Na`
D. `Na+H_(2)O rarr NaOH overset(CO_2) rarr Na_(2)CO_(3) overset(HCl) rarr underset("molten")Nacl overset( "electrolysis ") rarr Na`

Answer

A

Explanation

`2Na + 2H_(2)O rarr 2NaOH + H_(2) uarr`
`2NaOH + CO_(2) rarr Na_(2) CO_(3) +H_(2)O`
`Na_(2)CO_(3) + 2HCl rarr 2NaCl + H_(2)O + CO_(2)`
