Question

A compound contains a metal and sulfur. This compound goes through a combustion reaction such that compound X is produced from the metal atoms and compound Y is produced from the sulfur atoms in the reactant. What are the compounds X and Y?

A. X is carbon dioxide, and Y is sulfur dioxide.
B. X is a hydrocarbon, and Y is sulfur powder.
C. X is a metal oxide, and Y is sulfur dioxide.
D. X is a metal hydride, and Y is sulfur powder.

Answer 1

C

Step-by-step explanation:

Answer 2

The correct answer is option C.

Step-by-step explanation:

Metallic sulfides on combustion gives metallic oxides along with sulfur dioxide as product.During combustion reaction oxygen reacts with compound.

`M_2S_x+((3x)/(2))O_2\rightarrow M_2O_x+xSO_2`

So, when compound of containing metal and sulfur undergone combustion reaction it gives compound X and compound Y.

Compound X contains metal atom which means it is metal oxide.

Compound Y contains sulfur atom which means it is sulfur oxide.
