3. When a solution of sodium hydroxide is mixed with iron (II) chloride, a green precipitate is formed. What is the balanced equation for that reaction? O Fe2Cl(aq) + NaOH(aq) → Fe2OH(aq) + NaCl(a)
O Fe2 C (mg) + NaOH(aq) → Fe2OH(aq) + NaCl(aq)
O FeCl2(98) + NaOH(aq) → Fe(OH)2() + NaCl(ed)
O FeCl2(aq) + 2 NaOH(aq) → Fe(OH)2(8) + 2 NaCl(a)

the correct name for the n3 ion is azide. azide is a polyatomic anion with a -1 charge and is written as n3 -1. it consists of three nitrogen atoms bonded together. hope i . let me know if you need anything else.

the electrical  conductivity  of asolution  of an electrolyte is measured by determining the resistance of thesolution  between two flat or cylindrical electrodes separated by a fixed distance.
