Because they are two physically different, albeit closely-related chemical compositions:
Hydrochloric acid is what is generally used as a strong acid in industry and retail for use in Swimming Pools. It is an aqueous solution of HCl, which is a strong acid and therefore dissolves fully in the solvent (water) existing as it's constituent ions H+ and Cl-, separated and interacting with the very polar water molecules. Hydrochloric acid cannot be simply dried/evaporated to create Hydrogen Chloride.
Hydrogen Chloride is the anhydrous form of the molecule HCl as a ionic molecule. It is sometimes referred to as dry HCl or HCl(g), since there is no solvent present and at STP it exists as a gas. This Hydrogen Chloride can be simply bubbled through water to produce Hydrochloric acid. The reverse transformation is not possible, instead a chemical reaction must be used to create Hydrogen Chloride from various reagents (such as Sulfuric acid and Sodium Chloride)
Hydrogen peroxide is also known as H2O2, peroxide, and dihydrogen dioxide.
The name sodium chloride refers to the compound formed when the elements sodium and chlorine combine. Sodium and chlorine are the individual elements present in the compound, while sodium chloride is the compound name that indicates the specific combination of these elements.
The names are iron trichloride or ironIII) chloride.
The elements in hydrogen peroxide are hydrogen and oxygen.
H2S stands for hydrogen sulphide.It is a gas.Answer:H2S can be called many names, most commonly hydrogen sulfide. Alternate names include:Dihydrogen monosulfideDihydrogen sulfideSulfaneSulfurated hydrogenSulfureted hydrogenSulfur hydride
Hydrogen chloride is also know as hydrochloric acid, or muriatic acid, when in solution.
Chlorides are salts of hydrochloric acid.
HCl - The correct names are hydrogen chloride or hydrochloric acid.Depending upon concentration and volume ingested. But HCl is very corrosive and therefore dangerous.
In the stomach there is Gastric Acid which is composed of some other chemicals. Sodium Chloride (NaCl), Potassium Chloride (KCl), and even small amounts of Hydrogen Chloride (HCl or hydrochloric acid). See the related links for further information.
Sulfuric acid, hydrochloric acid, citric acid ...
Hydrogen peroxide is also known as H2O2, peroxide, and dihydrogen dioxide.
hydrogen, deuterium, and tritium.
When a metal reacts with an acid, it forms a salt and hydrogen gas. The metal displaces the hydrogen in the acid, leading to the formation of the salt (metal compound) and the release of hydrogen gas as a byproduct.
The names are thionyl chloride (SOCl2), sulfuryl chloride (SO2Cl2), and sulfur dichloride (SCl2).
Hydrosulfuric acid is H2S. H2S (aq) (H2SO4 is sulfuric acid). The acids with "hydro" at the start of their names are all derived from dissolved gases, e.g. hydrochloric acid is aqueous hydrogen chloride, hydrocyanic acid is aqueous hydrogen cyanide etc.
Oxygen, hydrogen, helium, carbon dioxide, methane, lithium
Hydrogen has three isotopes with different names: protium (1H), deuterium (2H), and tritium (3H). Each isotope has a different number of neutrons in its nucleus.
