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)
That when you pass it to a compound the ending of a word changes fromine (chlorine) to ide (chloride).
Calcium chloride can be made from limestone and hydrochloric acid, and if you do it that way you want concentrated acid to make the process run faster.
Calcium carbonate (CaCO3) , which goes by the mineral names of marble, limestone, or chalk. The reaction scheme is Hydrochloric Acid + Calcium Carbonate forms Calcium chloride , water and carbon dioxide ( which effervesces (bubbles)). The reaction equation is 2HCl(aq) + CaCO3(s) = CaCl2(aq) + H2O(l) + CO2(g)
HgCl2 - mercury(II) chloride. Hg2Cl2 is mercury(I) chloride
2 hydrogen atom and 2 oxygen atom
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.
Sulfuric acid, hydrochloric acid, citric acid ...
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.
Product will be metal salt and hydrogen Ex.) Hydrochloric acid and zinc ---> zinc chloride and hydrogen 2HCl + Zn ---> ZnCl2 + H2 Sulphuric acid + magnesium ---> magnesium sulphate and hydrogen H2SO4 + Mg ---> MgSO4 + H2 Ethanoic acid and calcium ---> calcium ethanoate and hydrogen (Acetic acid and calcium ---> calcium acetate and hydrogen , using the older names) 2CH3COOH + Ca---> Ca(OOCCH3)2 + H2

hydrogen, deuterium, and tritium.
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.
Calcium chloride can be made from limestone and hydrochloric acid, and if you do it that way you want concentrated acid to make the process run faster.
