Text Solution

Verified by Experts

These observations suggest that the substance (A) is sulphur (S), the gas (B) is nitrogen dioxide `(NO_(2))` , compound (C) is sodium thiosulphute `(Na_(2)S_(2)O_(3))` and the gase (D) is sulphur dioxide `(SO_(2))` . The reaction are as follows :
`S(A) + Na_(2)SO_(3) to Na_(2)S_(2)O_(3)`(C)
