How many atoms does CA PO4 2?
For example, the chemical formula that represents the compound calcium phosphate is Ca3(PO4)2. This formula shows that in one mole of this compound, there are 3 moles of Ca atoms that combine with 2 moles of the PO4(phosphate) groups, which gives a total of 2 moles of P atoms and 8 moles of 0 atoms.
How many atoms are there in Al2 SO4 3?
Answer: In this case, Al2 means 2 aluminums, (SO4)3 means 3 (SO4)s. The parentheses mean that the 3 has to be multiplied by whatever number of atoms you have of each element inside: 3×1 sulfurs, 3×4 oxygens. Now for the grand tally: 2 aluminum atoms + 3 sulfur atoms + 12 oxygen atoms = 17 atoms total in each molecule.
What is Fe3O4 and Fe2O3?
What is Fe3O4 called? FeO is called ferrous oxide while Fe2O3 is ferric oxide. So the Fe3O4 compound is called ferrous ferric oxide.
What is Fe3O4 10?
Fe3O4 is the chemical formula of Iron (II, III) oxide which has four oxygen atoms, three iron atoms.
Is Fe2O3 ionic or covalent?
It is represented by Fe2O3. The oxidation state of iron oxide is +3 and +2. The bond formed between iron and oxygen is due to the difference in electronegativity between the two atoms. Since iron is metal and oxygen is non-metal therefore the bonding between oxygen and iron is ionic.

What is rust Fe2O3?
Oxide Fe2O3 (high oxygen/low moisture)
Rust from Iron (III) oxides with high oxygen and low moisture results in brown rust. … It can be the result of a contaminate on the metal’s surface often originating from the manufacturing process.
How is Fe3O4 made?
Fe3O4 is formed with the combination of FeO and Fe2O3 i.e. ferrous oxide and ferric oxide.
How is Fe3O4?
How is Fe3O4 formed? – Quora. Using Ferrous Hydroxide(Fe(OH)2), one can synthesize Fe3O4, or magnetite, rather simply. Since magnetite is a well crystallized solid it is thermodynamically more stable than ferrous hydroxide, which can be oxidized by water under anaerobic conditions to make the magnetite.
