H2s
The formula for hydrogen heptiodide is HI7. It is formed by 7 iodine atoms bonding with a single hydrogen atom.
Hydrogen gas (H2) is a covalent molecule because it is formed by the sharing of electrons between the two hydrogen atoms. Ionic compounds are formed by the transfer of electrons between atoms, not sharing.
The formula for hydrogen plus hydrogen is H + H, which combines to form the molecule H2.
NO!!! It is a compound of hydrogen and sulphur. The bonds between hydrogen and sulphur are covalent. H2S ( hydrogen sulphide) is the sulphur analogue of water. H2S is the bad eggs smell that is given off from rotten eggs.
The formula for silver hydrogen carbonate is AgHCO₃. It is formed by combining silver cation (Ag⁺) and hydrogen carbonate anion (HCO₃⁻).
sulphur dioxide is formed from sulphur compounds when petrol is burned
If, by your slightly jumbled question, you meant "What compounds are the element of sulphur in?", then Sulphur trioxide, Sulphuric acid and the sulphates, sulphur hexafluoride, toxic solvent carbon disulphide, metal sulphides and the other oxides of sulfur which are formed by incomplete combustion; sulphur monoxide and sulphur dioxide.
There are two hydrogen atoms for every oxygen. The formula is H2O.
The chemical formula of hydrogen sulfide is H2S.
The formula for hydrogen heptiodide is HI7. It is formed by 7 iodine atoms bonding with a single hydrogen atom.
Hydrogen gas (H2) is a covalent molecule because it is formed by the sharing of electrons between the two hydrogen atoms. Ionic compounds are formed by the transfer of electrons between atoms, not sharing.
Hydrocarbons are organic compounds formed from hydrogen and carbon.
B2h3
BaS
The formula for hydrogen plus hydrogen is H + H, which combines to form the molecule H2.
NO!!! It is a compound of hydrogen and sulphur. The bonds between hydrogen and sulphur are covalent. H2S ( hydrogen sulphide) is the sulphur analogue of water. H2S is the bad eggs smell that is given off from rotten eggs.
These are called compounds unless an element, such as hydrogen, has been formed.
