This is a balanced chemical equation.
fe+3=..............* .9 =fe+2
In the balanced chemical equation 4Fe + 3O2 -> 2Fe2O3, the coefficient in front of iron (Fe) is 4.
Ag+
Yes, the reaction 4Fe + 3O2 -> 2Fe2O3 is a combination reaction. In this reaction, iron (Fe) reacts with oxygen (O2) to form iron(III) oxide (Fe2O3).
If Fe becomes Fe^2+ it has lost 2 electrons, and so the Fe has been OXIDIZED.
Fe
Any reaction occur.
combination
fe+3=..............* .9 =fe+2
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.
Yes, Fe (iron) plus S (sulfur) equals FeS (iron sulfide). If the iron ion is iron(ll) then it is iron(ll) sulfide; if it is iron(lll), then it iron(lll) sulfide.
It would be: 4Fe + 3O2 2Fe2O3
Ag+
In the balanced chemical equation 4Fe + 3O2 -> 2Fe2O3, the coefficient in front of iron (Fe) is 4.
The balanced equation for this reaction is Fe2O3 + 3 H2O = 2 Fe(OH)3.
This is the ion Fe(3+).
