Question

When A + Water → C + B, B is reacted with D, gas C again obtained. 'D' gives 'C' with H2SO4. B gives yellow colour with bunsen flame. C is a flamable gas then what would be A, B, C and D :

Answer 1

i dont know  but u get it plz tell me

Answer 2

Answer:

Na , NaOH , H2 , Zn

Explanation:

Given : B gives yellow colour in bunsen flame

only Sodium metal gives yellow colour in

bunsen flame.

Now C is a flammable gas and only Hydrogen is the gas which is flammable in

nature thus the compound C is Hydrogen.

Now ,

NaOH + D => H2So4 + DNao

Therefore, D is more reactive than Hydrogen

and less reactive than Na i.e; Zinc .

Thus, D is Zn .
