When a substance A reacts with water it produces a combustible gas B and a solution of substance C in water. When another substance D reacts with this solution of C, it also produces the same gas B on warming but D can produce gas B on reaction with dilute sulphuric acid at room temperature. A imparts a deep golden yellow colour a smokeless flame to Bunsen burner. A,B,C, and D respectively are `:`

When a substance a reacts with water, it produces a combustible gas B and a solution of substance C in water. When another substances D reacts with this solution of C . It also produce gas B on reaction with dilute sulphuric acid at room temperature . A imparts a deep golden yellow colour to the smokless flame of bunsen flame A,B , C and D are respectively

When a substance A reacts with water it produces a conbustible gas B and a solution of substance C in water. When another substance D reacts with this soution of C , it also produces the same gas B on warming but D can produce B on reaction with dilute sulphuric acid at room temperature. B on reaction with dilute sulphuric acid at room tempreture. A imparts a golden yellow colour to a smokeless flame of bunsen flame. A,B,C and D are respectively.

When a substance A reacts with water, it produces a combustible gas B and a solution of substance C in water. D reacts with this solution of C and produces the same gas B on warming. D can also produce gas B on reaction with dilute H_2SO_4 . A imparts a deep golden yellow colour to smokeless flame. A, B, C and D respectively are

When a substance 'A' reacts with water it produces combustible gas B and a solution of a substance 'C' in water . A has no reaction with the solution of 'C' When another substance 'D' reacts with this solution of 'C' it also produces the same gas 'B' even on reaction with dilute sulphuric acid at room temperature . Here A,B,C and D or respectively.

The reaction of an element A with water produces combustible gas B and an aqueous solution of C. When another substance D reacts with this solution C also produces the same gas B.D also produces the same gas even on reaction with dilute H_2 SO_4 at room temperature. Element A imparts golden yellow colour to Bunsen flame. Then A,B,C and D may be identified as
