Answer: a) [tex]FeO[/tex] and [tex]Fe_2O_3[/tex].
b) [tex]FeCl_2[/tex] and [tex]FeCl_3[/tex].
Explanation:
For formation of a neutral ionic compound, the charges on cation and anion must be balanced. The cation is formed by loss of electrons by metals and anions are formed by gain of electrons by non metals.
a) For [tex]Fe^{2+}[/tex] having an oxidation state of +2 and oxide anion with oxidation state of -2. They combine and their oxidation states are exchanged and written in simplest whole number ratios to give neutral [tex]FeO[/tex]. For [tex]Fe^{3+}[/tex] having an oxidation state of +3 and oxide anion with oxidation state of -2. They combine and their oxidation states are exchanged and written in simplest whole number ratios to give neutral [tex]Fe_2O_3[/tex].
b) For [tex]Fe^{2+}[/tex] having an oxidation state of +2 and chloride anion with oxidation state of -1. They combine and their oxidation states are exchanged and written in simplest whole number ratios to give neutral [tex]FeCl_2[/tex]. For [tex]Fe^{3+}[/tex] having an oxidation state of +3 and chloride anion with oxidation state of -1. They combine and their oxidation states are exchanged and written in simplest whole number ratios to give neutral [tex]FeCl_3[/tex].
a) The formulas for the compound two iron ions can form with oxide ions are [tex]\bold{FeO\; and\; Fe_2O_3}[/tex] Ferrous oxide and ferric oxide, respectively.
(b) The formulas for the compounds the two iron ions can form with the chloride ion [tex]\bold{FeCl_3\; and \; FeCl_2}[/tex] Ferric chloride and ferrous chloride, respectively.
Iron is a chemical element with atomic number 26 founds in the first transition series. Its symbol is Fe.
Ferrous oxide is a greenish to black powder that is mostly utilized as a glass color.
It can be made by heating a ferrous compound in the absence of oxygen or passing hydrogen over ferric oxide.
The mineral hematite contains ferric oxide, which is a reddish-brown to black powder.
It can be made synthetically by burning almost any ferrous compound in the presence of air.
Reacting ferrous chloride with chloride or nitric acid is a common way to make ferric chloride.
It's a chlorinating agent for silver, copper, and some organic compounds, as well as a precursor to a variety of ferric compounds.
By passing dry hydrogen chloride gas over red-hot iron, ferrous chloride is formed as yellow-green deliquescent (moisture-absorbing) crystals.
Ferrous chloride can also be made in a hydrated form.
Thus, these are the compound formed with the given two forms of iron.
