Ammonium (NH₄⁺), carbonate (CO₃²⁻). Name: Ammonium Carbonate.

Step14: Analyze NaBrO₃

Sodium (Na⁺), bromate (BrO₃⁻). Name: Sodium Bromate.

Step15: Analyze Fe₂O₃

Iron (Fe): O is -2, so 2Fe³⁺ (2(+3) + 3(-2) = 0). Name: Iron(III) Oxide.

Step16: Analyze Fe(IO₃)₂

Iron (Fe²⁺), iodate (IO₃⁻). Name: Iron(II) Iodate.

Step17: Analyze beryllium nitride (73)

Be²⁺, N³⁻. Formula: Be₃N₂ (3(+2) + 2(-3) = 0).

Step18: Analyze nickel(II) chloride (74)

Ni²⁺, Cl⁻. Formula: NiCl₂ (1(+2) + 2(-1) = 0).
