Question

Написать формулы карбонатов и гидрокарбонатов: K, Ba, Ca, Mg, Al, Cr, Fe,Ni, Zn, Ag, Hg, Cu, Pb.

Answer 1

Не скажу что у меня правильно но вот несколько вариантов. Минусы (цифры с минусами)с верху ставить в конце квадрытных скобок.  [Ag(NH3)2]- , [HgBr4]2-,  [Fe(CN)6]3-, [Zn(OH)4]2-, [Ni(CN)4]3-.
