Question

An unknown substance “X” on heating produces Y and Z. What do you
think X to be- element/compound/mixture? Give reason for your answer.

Answer 1

can't be determined

Explanation:

It cannot be determined because x can be any compound or mixture and y and z can be any products.

There are many compounds which break down on heating. And mixtures too.

Some specifications are required

Answer 2

Answer:

X is a mixture

Explanation:

X cannot be an element, because elements can't be broken down into smaller particles on heating. Also, it cannot be a compound as compounds do not divide into elements on physical changes like heating. It takes chemical reactions to break a compound into elements. I hope it helps Pointer.
