Question

A yellow coloured powder X is soluble in carbon disulphide. It burns with a blue flame forming suffocating smelling gas which turns moist blue Litmus red identify X and give chemical equation. Identify it is a metal or non metal

Answer 1

X+cs2 X+O2=XO2_suffocatingsmell gas S+O2=SO2 SO2+H2O=H2SO3 turns moist blue litmus red X is Sulphur it's a non metal.

Answer 2

Answer:

It is a non metal.

Explanation:

A yellow colored powder X is soluble in carbon disulfide. X is soluble in carbon disulfide (CS2). So X must be sulphur. Now if we burn oxygen then the sulphur reacts with oxygen and gives sulphur dioxide (SO2).

S+O2 =SO2

A colorless, nonflammable and liquefied gas with a penetrating odor. If we test it with litmus paper, it turns into red. That means it is acidic in nature. So it is non-metal.
