WebHBr + NH 3 net ionic equation. Net ionic equation for HBr + NH3 reaction is: NH3(aq) + H+(aq) = NH4+(aq) . A molecular equation must take into account and balance each compound’s phase. HBr (aq) + NH3(aq)= NH4Br (aq) It is necessary to convert the aqueous salts or chemicals in the equation into ions. WebState whether HBr is polar or nonpolar. Electronegativity: Electronegativity is the ability of an atom to attract electrons. On the periodic table, electronegativity increases toward the right and decreases as you move down. Answer and Explanation: 1. HBr is polar because there is an unequal electronegativity between the hydrogen and bromine atoms.
