When a solid mixture of NaHCO(3) and Na(...

When a solid mixture of `NaHCO_(3)` and `Na_(2)CO_(3)` is strongly heated to 500K in an open vessel, the mass of sample decreases. The decrease is-

A

Only due to `CO_(2)(g)` formed by decomposition of `Na_(2)CO_(3)`

B

Only due to `CO_(2)(g)` formed by decomposition of `NaHCO_(3)`

C

Only due to `CO_(2)(g)` formed by decomposition of `Na_(2)CO_(3)` and `NaHCO_(3)`

D

Due to `CO_(2)(g)` and water formed by decomposition of `NaHCO_(3)`
