Answer:

compound

Explanation:

We already know that the original substance was pure. If this substance was pure and it was powdery in nature then we have a footing to start from.

Secondly, a 4.93 g of shinny metallic liquid was left behind. This shinny metallic liquid must be an element.

Since there was a loss in mass during heating, it follows that there were other components of the pure powder.

If the reasoning stated above is correct, then the substance is a compound.
