FeO or Fe2O3
No, metalloids are elements, Fe2O3 is a compound known as iron III Oxide
The thermite doesn't exactly make its own oxygen, it's already there in the iron oxide (Fe2O3), and simply get's "transferred" in the reaction: Fe2O3 + 2Al --> 2Fe + Al2O3
No, Fe2O3 is ionic
Hematite is an oxide of iron in its "raw" or "natural" form. It's a mineral, and it's iron(III) oxide. Its formula is Fe2O3.Hematite is Fe2O3.
15 Fe2O3 has 2 + 3 atoms = 5 atoms Multiply the whole thing by 3 and you end up with 15 atoms.
Fe2O3
in one molecule of Fe2O3 there would be 3 oxygen atoms
Hematite is rust or Fe2O3 a.k.a. Iron(III)oxide but if you want to make crystal hematite that's used for jewellery than you have to heat up rust ABOVE 950 degrees celsius
Fe2O3 (diiron trioxide) is a chemical compound not am element.
To calculate the weight of Fe3O4 needed to furnish 0.5430g of Fe2O3, you need to consider the molar masses of Fe3O4 and Fe2O3. The molar mass of Fe3O4 is 231.535 g/mol, and of Fe2O3 is 159.69 g/mol. By using the molar ratios between Fe3O4 and Fe2O3, you can determine that 0.5430g of Fe2O3 would require 0.7799g of Fe3O4.
The oxide Fe2O3 has 3 oxygen atoms in the molecule.
