Hydrochloric acid has the chemical formula HCl. It is a compound.
There is no chemical reaction between sod chloride solution and water, it would just dilute the sod chloride solution.
The chemical formula for hydrochloric acid is HCl.
No, "H2Cl" is not the chemical formula for hydrochloric acid. The chemical formula for hydrochloric acid is "HCl," which represents a molecule consisting of one hydrogen atom (H) and one chlorine atom (Cl) bonded together. "H2Cl" would not be a valid chemical formula for any known chemical compound
Be careful with your terminology.Mixing aluminum and hydrochloric acid is not a chemical change.The resulting reaction, however, is a chemical change.
