A black solid is heated in a tube that is completely evacuated of air. Hydrogen is added to the tube. An orange powder is formed and water vapor is seen on the outside of the tube. Is the original solid an element or compound? Can you identify the chemical?

    The black solid is a compound and not an element. My best guess would be the black solid is Hg2O and the orange powder is HgO.
