WebSep 15, 2024 · The oxygen atom has a 2− charge as an ion. To balance the positive and negative charges, we look to the least common multiple—6: two iron 3+ ions will give 6+, while three 2− oxygen ions will give 6−, thereby balancing the overall positive and negative charges. Thus, the formula for this ionic compound is \ce {Fe2O3}. WebQuestion 1. A mixture of 20.2 g of P and 79.0 g of Cl2 reacts completely to form PCl3 and PCl5 as the only products. Find the mass of PCl3 that forms. Question 2. A solution contains Cr3+ ion and Mg2+ ion. The addition of 1.00 L of 1.52 M NaF solution is required to cause the complete precipitation of these ions as CrF3 ( s) and MgF2 ( s ).
WebIn this work, we demonstrate that concept in the phosphor LaScO3:Cr3+ by co-doping with various lanthanide ions that partially substitute the La3+ ions of the host. It is demonstrated that the incorporated lanthanide ions affect the bond lengths of the [CrO6]9- octahedra in the structure and thus, have a subtle impact on the local crystal field ...
