The NH3 compound name is ammonia or nitrogen trihydride.Actually,the common name of NH3 is ammonia and the systematic or IUPAC name for NH3 is nitrogen  trihydride . Also,the IUPAC name of NH3 is ammonia.The IUPAC has recognized the common name of NH3 as systematic name. Explanation: In NH3 compound,both nitrogen and hydrogen are nonmetals,so to name NH3 compound we will apply the rules for binary compounds with two non metals. Rules:  1. Firstly,write the name for the first element using a prefix if there is more than one atom.   2. Then,write the stem of the second element and add the suffix -ide. Use a prefix to indicate the number of atoms for the second element. ●Remember that two nonmetals form a covalent compound.  ●Notice that The name of the second element retains the -ide ending as though it were an anion. Now for NH3 compound,we get nitrogen trihydride.

To name  NaCO3 compound,at first write the name of sodium ion,then write the name of carbonate ion. NaCO3 =Sodium carbonate 【 Rules: 1)Write the name of the cation 2)Write the name of the anion】 This is an ionic compound. Next

  P2O5 Compound Name Answer: The IUPAC or systematic name for the compound P2O5 is phosphorus (V) oxide.Here the roman numeral  (V) indicates the oxidation number of phosphorus that is +5. Here is the alternative name of P2O5.P2O5 is called diphosphorus pentoxide.Sometimes,we leave the prefix di- and we call P2O5 as phosphorus pentoxide. Look, Penta + Oxide ---a-->Pentoxide. So, we  are getting three name for P2O5 compound.These are: ● P hosphorus pentoxide ●Di phosphorus pentoxide ●P hosphorus (V) oxide
