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)
