Webb9 okt. 2024 · Magnesium is Mg. It forms the ion Mg 2+. Sulfate refers to the sulfate ion, which is a polyatomic ion with formula SO 42-. As their charges have the same absolute value, which is 2, their ratio in an ionic compound is 1:1. Thus Magnesium Sulfate is MgSO 4. (As you see, the 2+ and 2- cancel each other out.) Webb5 juli 2016 · Answer is: formula is Al₂ (CO ₃) ₃. Aluminium carbonate (Al₂ (CO₃)₃) has neutral charge. Because aluminium cation has positive charge 3+ and carbonate anion has negative charge 2-, for right chemical formula, we need two aluminium cations and three carbonate anion: charge of the molecule = 2 · (3+) + 3 · (-2). charge of the molecule = 0. semrush pro account username and password https://cdmestilistas.com
