fe+3=..............* .9 =fe+2
Ag+
The chemical reaction is:Fe2O3 + 3 Zn → 2 Fe + 3 ZnO
The reaction is:4 Fe + 3 O2= 2 Fe2O3
Formula = Fe(ClO4)2Formula: Fe(ClO4)2
There are similar number of protons in the ion and the atom. Fe+3 ion contains 26 protons.
Fe 2+ is Ferrous Fe 3+ is Ferric
A. Fe^2+ ==> Fe^3+ + e- is an oxidation reactionB. Fe^3+ +e- ==> Fe^2+ is a reduction reactionC. Fe(s) ==> Fe(l) is neither an oxidation nor a reduction reaction. It is a phase change.D. Fe + 2e- ==> Fe^2+ is not a possible reaction.
2 Fe2O3 + 12 HNO3 -> 4 Fe(NO3)3 + 6 H2O
Iron (Fe)
This is the ion Fe(3+).
Yes
When iron (Fe) reacts with chlorine gas (Cl2), they form iron (III) chloride (FeCl3) according to the equation: 2 Fe + 3 Cl2 → 2 FeCl3. This reaction is a redox reaction where iron is oxidized and chlorine is reduced.
Ag+
The chemical reaction is:Fe2O3 + 3 Zn → 2 Fe + 3 ZnO
Use Avogadro's number. 2 mole Fe(3+) ( 6.022 X 10^23/1 mole Fe(3+) ) = 1.20 X 10^24 ions of Fe(3+)
Fe + 3AgNO3 ==> Fe(NO3)3 plus 3Ag The oxidation number of Ag in AgNO3 (on the left side) is 1+ and in Ag (on the right side), it is zero. Thus, in this reaction, silver (Ag) has been reduced.
The reaction is:4 Fe + 3 O2= 2 Fe2O3
