This is a decomposition reaction, where a compound is broken down into its constituent elements. Mercury oxide is a compound of both mercury and oxygen. So the decomposition of mercury oxide would *yield* mercury and oxygen. Therefore, the “silvery substance” would be mercury (mercury would no longer be in a compound with oxygen).
