Oxygen was discovered by Joseph Priestley in 1774 when he focused sunlight on a sample of mercuric oxide and collected the resulting gas.

The Koenigs-Knorr reaction is the condensation of glycosyl halides and alcohols in the presence of metal salts such as silver carbonate or mercuric oxide.

Mercury batteries with cathodes made of a mix of mercuric oxide and manganese dioxide have output voltage of 1.4 V and a more sloped discharge curve.
14.
Scheele performed numerous experiments in which he heated substances such as saltpetre ( potassium nitrate ), manganese dioxide, heavy metal nitrates, silver carbonate and mercuric oxide.
15.
The Koenigs Knorr reaction can be performed with alternative promoters such as various heavy metal salts including mercuric bromide / mercuric oxide, mercuric cyanide and silver triflate.
16.
Priestley called the new substance " dephlogisticated air ", which he made in the famous experiment by focusing the sun s rays on a sample of mercuric oxide.

Also found were a plastic bag with 30 kilograms ( 65 pounds ) of poisonous powder, mercuric oxide, and a hydroxide liquid, believed used in making bombs, Jabali said.

Inorganic mercury compounds or mercury salts, more commonly found in nature, include mercuric sulphide ( HgS ), mercuric oxide ( HgO ) and mercuric chloride ( HgCl 2 ).

In other words, during discharge, zinc is oxidized ( loses electrons ) to become zinc oxide ( ZnO ) while the mercuric oxide gets reduced ( gains electrons ) to form elemental mercury.
