When the formula equation #Fe_3O_4 + Al -> Al_2O_3 + Fe# is correctly balanced what is the coefficient of #Fe#?
1 Answer
Well...
Explanation:
And so the oxides are reduced to iron...
And aluminim metal is oxidized to alumina...
And we add
And now we cancel common reagents...
And finally....
And this looks balanced to me... but please check my 'rithmetic; all care taken but no responsibility admitted. And this is an important reaction practically. Where there is a join in the track of a railway line, they fill it with the iron oxide and alumina, and have at it with a blow torch. The aluminum oxidizes to alumina (and is expelled from the join), and the molten iron welds the track together....
