Why is Fe the correct chemical formula for iron oxide?
It isn't Fe is simply iron There are three common oxides of iron. Iron II oxide, FeO (Fe2+ ion and O2- ion) Iron III oxide Fe2O3 (2 Fe3+ ions, 3 O2- ions) Iron II, III oxide Fe3O4 (2Fe 3+ ions, 1 Fe2+ ion, 4O2- ions) The formula are such that the overall charge of each oxide balances out to zero.
What is the chemical symbol for oxide ion?
FeO (iron oxide . it's another name) The correct answer is Iron(III)oxide which is Fe2O3
Does the electron configuration denote the ratio of ions in the compound?
No. The formula unit for an ionic compound denotes the ratio of ions in the compound. For example, the formula unit NaCl indicates a ratio of 1 sodium ion to 1 chloride ion, CaCl2 indicates a ratio of 1 calcium ion to 2 chloride ions, and Fe2O3 indicates a ratio of 2 iron ions to 3 oxide ions.
What elements make up iron carbonate?
Iron carbonate is formed from iron, carbon, and oxygen, where carbon and oxygen are in a carbonate ion (-2) form.Iron II carbonate (known as siderite) has the formula FeCO3, where iron has a valence of 2 and the carbonate ion has a valence of -2.Iron III carbonate (ferric carbonate) has the formula Fe2(CO3)2 where iron has a valence of 3.
Molar mass of Iron 3 carbonate?
I'm sure that you cannot have the formation of Iron (iii) carbonate due to it's strong acidic nature, however when we have iron(iii)hexa-aqua ions and add some carbonate, which acts as a base, we form iron(II) carbonate. FeCO3. This is just what I have learnt feel free to challenge or correct me anyone.
The charge on the iron ion in the salt Fe2O3 is?
+3
What is the difference between FeO and Fe2O3?
FeO is iron II oxide or ferrous oxide. In this compound iron forms a 2+ ion which combines with oxygen(which forms a 2- ion) in a 1:1 ratio Fe2O3 is iron III oxide or ferric oxide. In this compound iron forms a 3+ ion which combine with oxygen (again a 2- ion) in a 2:3 ratio. In Fe2O3 iron is in its highest oxidation state. FeO is black, Fe2O3 is red. Fe2O3 is more common. FeO is a better conductor than Fe2O3.
What is the chemical formula for iron 2 and oxygen?
Fe3O2. But it's not right! Oxygen forms a 2- ion and iron can be 2+ or 3+. So the formulae of iron oxide can be FeO or Fe2O3.
Is Fe2O3 an acid?
Fe2O3 is a base but it is not an alkaline. Its name is iron oxide, where the ion for Fe is 3+ and the ion for O is 2-. That's why it becomes Fe2O3. It is in solid condition, just like rust
What is pyrite's formula?
Pyrite is an iron ore, which has the chemical formula FeS2 (Iron (II) Sulfide) The sulfide ion present is S22-
Fe2O3 is named iron oxide because it contains which type of iron ions?
Fe2O3 is named iron oxide because it contains Fe+ ions.
What is Fe and Fe2o3 in terms of chemistry?
The first Fe represents an iron atom in the 0 oxidation state while the Fe in Fe2O3 represents iron ion in the +2 oxidation state
Why is Fe2O3 named iron III oxide?
Iron exists in two oxidation states: Fe2+ and Fe3+. To distinguish between these two oxidation states and to specify which kind of ion will form on dissociation, they are named as Iron II and Iron III. Now, Fe2O3 contains the Fe3+ ion. That is why, it is called iron III oxide.
Why is Fe the correct chemical formula for iron oxide?
It isn't Fe is simply iron There are three common oxides of iron. Iron II oxide, FeO (Fe2+ ion and O2- ion) Iron III oxide Fe2O3 (2 Fe3+ ions, 3 O2- ions) Iron II, III oxide Fe3O4 (2Fe 3+ ions, 1 Fe2+ ion, 4O2- ions) The formula are such that the overall charge of each oxide balances out to zero.
What is theCorrect Formula For the iron III ion?
The iron III ion is Fe3+
How do you find the chemical formula for iron III oxide?
The name iron III oxide shows that you have two types of ion in the compound, the iron III ion (Fe3+) and the oxide ion (O2-). What you need to do is find what ratio to combine the ions in so that the positive and negative charges cancel out to zero. One way of doing this is to switch the numbers of each ion's charge, and assign it to the opposite ion, so in this case you get 2 Fe3+ ions and 3 O2- ions. So the formula is Fe2O3
What is iron iii?
Iron(III) oxide or ferric oxide has the chemical formula Fe2O3. It is considered as one of the three main oxides of the element iron.
