25 Σεπ 2022 · The \(\ce{NH4}\) in the formula represents the ammonium ion, \(\ce{NH4^{+}}\), which indicates that this compound is ionic via method 2 \(\ce{NH4Cl}\), ionic d.
The \(\ce{NH4}\) in the formula represents the ammonium ion, \(\ce{NH4^{+}}\), which indicates that this compound is ionic. Both oxygen and fluorine are nonmetals. Therefore, \(\ce{OF2}\) is not ionic.
Define ionic and molecular (covalent) compounds; Predict the type of compound formed from elements based on their location within the periodic table; Determine formulas for simple ionic compounds
Ionic compounds have a [+] cation and a [-] anion. We use the Principle of Charge Neutrality, that is, for an ionic compound to be stable its chemical formula MUST BE NEUTRAL. So you do not need to state the number of cations and anions, you only need to state what they are (and what their charge is).
AMMONIUM SULFIDE, SOLUTION is a strongly alkaline aqueous solution. Reacts with acids to generate toxic and flammable gaseous hydrogen sulfide. Reacts with bases to release gaseous ammonia. May react vigorously with oxidizing agents, including inorganic oxoacids, organic peroxides and epoxides.
The compound’s name is ammonium sulfide. Because the ions have the same magnitude of charge, we need only one of each to balance the charges. The formula is AlPO 4 , and the name of the compound is aluminum phosphate.
