4Fe + 3O2 --> 2Fe2O3
The balanced equation is 3 Fe3O4 + 8 Al -> 4 Al2O3 + 9 Fe. Therefore, the coefficient of Fe is 9.
The balanced chemical equation for the reaction is: 3FeO4 + 8Al -> 4Al2O3 + 3Fe Therefore, the coefficient of Fe is 3.
One assumes this is a single displacement reaction. 2Au + FeSO4 --> Au2SO4 + Fe
Zn2 + Fe3NO3 -> Zn3NO2 + Fe3
The balanced equation is 2Fe2O3 + 4Al ----> 2Al2O3 + 3Fe. The coefficient of Fe is 3.
The balanced equation is 3 Fe3O4 + 8 Al -> 4 Al2O3 + 9 Fe. Therefore, the coefficient of Fe is 9.
This is a balanced chemical equation.
The balanced chemical equation for the reaction is: 3FeO4 + 8Al -> 4Al2O3 + 3Fe Therefore, the coefficient of Fe is 3.
Yes
One assumes this is a single displacement reaction. 2Au + FeSO4 --> Au2SO4 + Fe
O does not exist by itself. The balanced equation would be 4Fe + 3O2 --> 2Fe2O3
Zn2 + Fe3NO3 -> Zn3NO2 + Fe3
This equation is 2 Fe + 3 Cl2 -> 2 FeCl3.
The balanced equation is 2Fe2O3 + 4Al ----> 2Al2O3 + 3Fe. The coefficient of Fe is 3.
The balanced chemical equation for the reaction of iron (Fe) with copper (Cu) is: Fe(s) + CuSO4(aq) → FeSO4(aq) + Cu(s)
Your unbalanced equation is _Al + _Cr2O3 ----> _Cr + _Al2O3. Multiply aluminum (Al) and chromium (Cr) ratio by 2, so each side has the same amount of each element. As a result, the equation 2Al + Cr2O3 -----> 2Cr + Al2O3 is balanced. This is a single replacement reaction.
The balanced equation for the reaction between iron and ammonium thiocyanate is: Fe + 3NH4SCN -> Fe(SCN)3 + 3NH4
