Is HBR an ionic or covalent compound?

It is best to think of all hydrogen halides as covalent polar molecules, with the polarity increasing in the order HI < HBr < HCl < HF, as suggested by the electronegativity differences. If every ionic compound is solid at 298K, the first answer is right. I mean, those molecules you mention would not be ionic bonded.
A.

Is nh3 an ionic compound?

NH3, also known as ammonia is a covalent compound. Reason being: Hydrogen and Nitrogen are both non metals and do not have the tendency to donate their electrons, which is a necessary condition for ionic bonds, as a result ionic compund is not possible.
  • Is Ki an ionic compound?

    Potassium iodide
  • Is KCL an ionic compound?

    Potassium chloride naturally occurs as a white or colorless solid that has a powdery, crystalline appearance. Its chemical formula is KCl, consists of one potassium (K) atom and one chlorine (Cl) atom. An ionic compound is made of a metal element and a nonmetal element.
  • Is nh4+ ionic or covalent?

    When the ammonium ion, NH4+, is formed, the fourth hydrogen is attached by a dative covalent bond, because only the hydrogen's nucleus is transferred from the chlorine to the nitrogen. The hydrogen's electron is left behind on the chlorine to form a negative chloride ion.
B.

Is iron oxide a molecular or ionic compound?

Iron as an ion can have +2 or +3 as its oxidation state. When forming compounds with oxygen (almost always with an oxidation state of -2), the compounds formed could be FeO, Fe2O3, or Fe3O4. So iron oxide is a polar covalent compound with ionic character.
  • Is Iron Oxide an ionic compound?

    Fe loses three electrons**. Oxygen gains two electrons to have an octet. The ionic bond between ions results from the electrostatic attraction of opposite charges. The final formula of iron oxide is Fe2O3.
  • Is iron Ionic?

    Like many elements, iron (chemical symbol Fe) can exist in more than one chemical form, or "oxidation state." The two most common forms for iron are Fe(II), in which the iron ion shares two of its electrons, and Fe(III), in which it shares three electrons. As a result, iron was most often found in the Fe(II) state.
  • Is silicon dioxide a covalent or ionic bond?

    Silicon dioxide has a giant covalent structure. Part of this structure is shown in the diagram - oxygen atoms are shown as red, silicon atoms shown as brown: Each silicon atom is covalently bonded to four oxygen atoms. Each oxygen atom is covalently bonded to two silicon atoms.
