Covalent
BeH2 is a covalent compound because beryllium typically forms covalent bonds with hydrogen. HCl is considered an ionic compound because hydrogen chloride typically forms an ionic bond between the hydrogen and chlorine ions.
HCl gas is a covalent molecular compound, HCl in water dissociates to form H+(aq) + Cl-
HCl (Hydrogen Chloride) is a covalent compound and forms a covalent bond. However, if water is added to hydrogen chloride, it forms hydrochloric acid which is an ionic compound that has ionic bonds.
Hydrogen Chloride (the gas) has covalent bonds, but Hydrochloric acid forms ionic bonds. As to why this occurs, I am clueless
H-ClA single covalent bond between the hydrogen and the chlorine
SO3 does not form ionic bonds; it forms covalent bonds. CO2 also forms covalent bonds due to its molecular structure. NaCl and HCl both have ionic bonds because they are formed between a metal (Na) and a nonmetal (Cl) in NaCl, and a metal (H) and a nonmetal (Cl) in HCl.
Hydrochloric acid (HCl) is a covalent compound, not ionic. BTB (bromothymol blue) is a pH indicator that changes color based on the acidity or basicity of a solution.
Hydrogen Chloride (the gas) has covalent bonds, but Hydrochloric acid forms ionic bonds. As to why this occurs, I am clueless
HCl is a polar covalent compound. When it is dissolved in Polar solvent H2O, it is ionized into its constituent ions H+ & Cl-. But when it is present gaseous form then it remains as Covalent compound HCl.
KCl is not a covalent compound; it is an ionic compound. It is made up of a metal (K) and a non-metal (Cl) bonded together through ionic bonds, not sharing electrons like in covalent compounds.
HCL is covalent. This is the type of bond that forms with the combination of Hydrogen and Chloride
I'm assuming you mean hydrochloric acid, HCl? This would be a covalent molecule, because of both atoms being nonmetals.
