Want this question answered?
The reaction is:4 Fe + 3 O2= 2 Fe2O3
iron reacts with air to form rust
No, there is no change in any oxidation states.
The coefficient of Fe2O3 is 1
2 Fe + 3 CuO -> Fe2O3 + 3 Cu
81.93%
Carbon
The balanced equation for this reaction is Fe2O3 + 3 H2O = 2 Fe(OH)3.
Fe2O3 + 3CO -----> 2Fe + 3CO2
The reaction is:4 Fe + 3 O2= 2 Fe2O3
That is an oxidation reaction (I am translating the numbers into subscripts) which in this case is also called rusting.
Fe2O3 + 2Al ===> Al2O3 + 2FeIn this reaction the number of moles of Al2O3 produced is dependent on the number of moles of Fe2O3 and Al that one starts with. For every 1 mole Fe2O3 and 2 moles Al, one gets 1 moles of Al2O3.
displacement reaction............ u people have to find the answers instead asking others without shame..............
Fe2O3 + H2SO4
iron reacts with air to form rust
No, there is no change in any oxidation states.
2 Fe2O3 + 12 HNO3 -> 4 Fe(NO3)3 + 6 H2O
