Which of the following sequence of chemcial reaction is correct?

Options

A. `Na+O_(2)rarrNa_(2)Ooverset(HCl(aq))rarrNaCloverset(CO_(2))rarrNa_(2)CO_(3)overset(Delta)rarrNa`
B. `Naoverset(O_(2))rarrNa_(2)Ooverset(H_(2)O)rarrNaOHoverset(CO_(2))rarrNa_(2)CO_(3)overset(Delta)rarrNa`
C. `Na+H_(2)OrarrNaOHoverset(HCl)rarrNaCloverset(CO_(2))rarr`
D. `Na+H_(2)OrarrNaOHoverset(CO_(2))rarrNa_(2)CO_(3)overset(HCl)rarrunderset("Molten")(NaCl)overset("electrolysis")rarrNa+Cl`

Answer

d

Explanation

`2Na+2H_(2)Orarr2NaOH+H_(2)uparrow`
`2NaOH+CO_(2)rarrNa_(2)CO_(3)+H_(2)O`
`Na_(2)CO_(3)+2HClrarr2NaCl+H_(2)O+CO_(2)`

In the case of options (a),(b) and (c), the last step on heating
`Na_(2)CO_(3)overset(Delta)rarr` Thermally stable
