What is the chemical HgOH?
HgOH would be called mercury(I) hydroxide or mercurous hydroxide. This is a compound that is not well characterised, in other words it is reported by chemists but (as far as I know) the existence of the solid compound has not been proven- e.g. by x-ray crystallography. Some authors say it only exists in solution. It would contain the diatomic Hg22+ ion and the formula would be written Hg2(OH)2.

Does the planet Mercury have oceans?
There are no lakes, oceans or other bodies of water on Mercury. The temperature at the equator is near 800 degrees Fahrenheit during the day and -280 degrees at night as the planet has no atmosphere with which to contain the temperature. Any water on the surface of Mercury would boil away quickly and escape into space because of Mercury's low gravity, and the constantly blowing solar wind.
