HCl is hydrogen chloride
HNO5 ?? re write it correctly
naming the chemical substances is a vast subject. different substances are named differently. There are some rules to name the compounds. these rule are called IUPAC rules.
Name the positive ion or atom which has the most positive oxidation state first, then name the negative ion or more negative species. If the negative ion/species is on its own then the ending is IDE as in sodium CHLORIDE NaCl. If its with oxygen then it ends in ATE as in sodium SULPHATE NaSO4.
At A'level and some GCSE courses you have to name species by their oxidation state. eg Copper (II) oxide CuO is so named as we are talking about the copper 2+ ion.
Common trivial names that take precident are..
Water not Hydrogen oxide
Ammonia not Nitrogen hydride
and the 3 strong acids.
Hydrochloric acid not hydrogen chloride unless we are talking about the pure gaseous state
Nitric acid not Hydrogen nitrate
Sulphuric acid not hydrogen sulphate.
Organic molecules ..well that's another matter
Teddie, above, has it pretty well covered, Apart from the exceptions to the IDE rule All compound which only contain two elements end in -ide except AMMONIUM chloride, sulphide etc. hydroxides and some acids. Your two examples HNO3 and HCl are nitric acid and hydrochloric acid respectively.
