H2SeO4.
The selenic acid (H2SeO4) is colorless.
Formula: Se8
Slobodan Selenic was born on June 7, 1933, in Pakrac, Croatia, Yugoslavia.
Slobodan Selenic died on October 27, 1995, in Belgrade, Serbia, Federal Republic of Yugoslavia.
SeO3 would be acidic, tending to make selenic acid H2SeO4
HSeO3 is the chemical formula for selenous acid, a weak acid containing selenium in the +4 oxidation state. It is used in chemical synthesis and as a reagent in analytical chemistry.
=> Aqua regia, a mixture of concentrated hydrochloric acid and nitric acid in 1:3 ratio, can dissolve gold. It is to be used readily or it would decompose.Au + HNO3 + 4 HCl ----> HAuCl4 + NO + 2 H2O=> Hot and concentrated Selenic acid(H2SeO4) can also dissolve gold.2 Au + 6 H2SeO4 ----> Au2(SeO4)3 + 3H2SeO3 + 3 H2O=> Concentrated solution of Potassium cyanide(KCN), in presence of oxygen, can dissolve gold4 Au + 8 KCN + O2 + 2 H2O → 4K[Au(CN)2] + 4 KOH=> Mercury can dissolve gold to form an alloy, called amalgam.
The correct formula is H2Se. Because it is an acid, hydrogen needs to be at the beginning. Hydrogen has an ionization of +1 and selenium (from which you get selenic) has -2, so you'll need 2 atoms of hydrogen (H) to balance out 1 atom of selenium (Se). So you'll have H2Se.
