The correct formula for gallium oxide is Ga2O3.
Nitrogen(IV) oxide is N2O4.
Yes, the correct formula for calcium oxide is CaO.
The correct balanced formula for cesium oxide is Cs2O.
The correct formula for aluminum oxide is Al2O3.
Formula: FeBr3
The correct chemical formula for copper oxide is Cu2O for copper(I) oxide (cuprous oxide) and CuO for copper(II) oxide (cupric oxide).
The balanced equation for the thermite reaction is: 2Al + Fe2O3 -> Al2O3 + 2Fe. This means that 2 moles of aluminum react with 1 mole of ironIII oxide. Therefore, if 5.591 moles of aluminum are used, 2.7955 moles of ironIII oxide will react. Since 4.821 moles of ironIII oxide are provided, the excess reagent is aluminum. The amount of excess aluminum left over is 5.591 moles - 2.7955 moles = 2.7955 moles.
The chemical formula for aluminum oxide is Al2O3.
This formula is MgO.
the correct formula unit for the ionic compound barium oxide is BaO.
