WebbQ.20 At what temperature will R.M.S speed of the molecules of the second member of the homologous. series CnH2n+2 be the same as that of oxygen at 527°C. (A) 750°C (B) 477°C (C) 580.3°C (D) 1227°C. Q.21 The volume of two gases X and Y (having different molecular masses) are the same under identical. WebbSo to figure how iron's charge it would be: (1)x + (1)-2 = 0, or x = 2, the 1's in parentheses being the number of iron and oxygen atoms. So iron has a +2 charge. Naming it would look like Iron (II) oxide, with the roman numeral 2 showing iron's oxidation state.

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
