The correct chemical formula for a molecule of N3 and H+ would be NH4+, forming the ammonium ion.
The chemical formula for sodium selenide is Na2Se.
This is not a chemical formula or equation.
Cobalt phosphate has the chemical formula Co3(PO4)2.
It forms SnCl2 . It is called Stannous Chloride
In the chemical formula H2SnO6 n has a value greater than 2.
The chemical formula for chlorine is Cl. When two chlorine atoms combine, they form a diatomic molecule, so the chemical formula for two chlorine atoms combined is Cl2.
When hydrogen, lithium, and beryllium atoms combine, they form a molecule with the chemical formula LiHBe. This molecule would have a unique set of properties based on the different characteristics of each element.
The chemical formula for sodium selenide is Na2Se.
This is not a chemical formula or equation.
There are 2 sulfur atoms in the chemical reaction H2S plus SO2 plus H2.
The correct balanced chemical equation for Ca^2+ reacting with NO2^1- is Ca^2+ + 2NO2^- -> Ca(NO2)2. This equation shows that one calcium ion reacts with two nitrite ions to form one molecule of calcium nitrite.
Cobalt phosphate has the chemical formula Co3(PO4)2.
The chemical formula for NH is ammonia (NH₃) and the chemical formula for CO is carbon monoxide. When they react, they form the compound HCN (hydrogen cyanide).
CrO4-2
The formula for hydrogen plus hydrogen is H + H, which combines to form the molecule H2.
H2O is 2 hydrogens plus 1 oxygen and that makes the chemical formula for water.
C6H7Cl3 , trichloor-cyclohexene
