hydrogen sulfide. The term binary compound means one that contains only two elements, and all the others listed contain three elements.
Mercury (I) Sulfide
iron(II) sulfide + sulfuric acid --> hydrogen sulfide + iron(II) sulfate FeS + H2SO4 --> H2S + FeSO4
The formula for ammonium sulfide is (NH4)2S. Therefore, each formula unit contains 8 hydrogen atoms.
The answer is a compound
(NH4)2S i think
Mercury (I) Sulfide
there are 1.30e25 Hydrogen atoms in 2.70 mol Ammonium Sulfide
there are 1.30e25 Hydrogen atoms in 2.70 mol Ammonium Sulfide
AMMONIUM SULFIDE
Hydrogen persulphide, or hydrogen di0sulphide. It has the structure 'H-S-S-H'.
iron(II) sulfide + sulfuric acid --> hydrogen sulfide + iron(II) sulfate FeS + H2SO4 --> H2S + FeSO4
The KIA medium has an iron salt-ferric ammonium citrate- and sodium thio sulfate. The ferric ions bind with the hydrogen sulfide to then form ferrous sulfide, which gives off a black percipitate that can be seen on the media.
The formula for ammonium sulfide is (NH4)2S. Therefore, each formula unit contains 8 hydrogen atoms.
The compound (NH4)2S is ammonium sulfide.
Hydrogen sulfide (H2S) is an inorganic compound.
Hydrogen sulfide (H2S) is an inorganic compound.
A sufide is an anion form of the element sulfur. It can form compounds if it combines with other elements. Sulfide on it's own is not a compound, you need a prefix to that like Hydrogen Sulphide. Do not get this mixed up with a sulfate; you can get copper sulphate but not copper sulfide.
