Dejanras

Answer is: D) mercury(II) oxide → oxygen + mercury.

Balanced chemical reaction: 2HgO(s) → 2Hg(l) + O₂(g).

This is example of chemical decomposition.

Chemical decomposition is the separation of a single chemical compound (in this example mercury(II) oxide) into its two or more simpler compounds (in this example mercury and oxygen).
