3FeO4 + 8Al --> 3Fe + 4Al2O3
The balanced equation is 3 Fe3O4 + 8 Al -> 4 Al2O3 + 9 Fe. Therefore, the coefficient of Fe is 9.
You need 4Al and 3O2 This will give you 2 Al2O3
This equation is Al2O3 + 6 HCl = 2 AlCl3 + 3 H2O.
The balanced chemical equation is: 2HNO3 + Al2O3 --> 2Al(NO3)3 + 3H2O
The balanced equation should be 2Al + 6HCl -> 2AlCl3 + 3H2. Therefore, the coefficient of HCl is 6.
The balanced equation is 3 Fe3O4 + 8 Al -> 4 Al2O3 + 9 Fe. Therefore, the coefficient of Fe is 9.
You need 4Al and 3O2 This will give you 2 Al2O3
This equation is Al2O3 + 6 HCl = 2 AlCl3 + 3 H2O.
The balanced equation is: C5H12 + 8O2 → 5CO2 + 6H2O. Therefore, the coefficient for oxygen in the balanced equation is 8.
The balanced chemical equation is: 2HNO3 + Al2O3 --> 2Al(NO3)3 + 3H2O
The balanced equation should be 2Al + 6HCl -> 2AlCl3 + 3H2. Therefore, the coefficient of HCl is 6.
Al2O3 + 6HBr = 2Albr3 + 3H2O
The coefficient of HCl in the balanced equation is 2. This is because the balanced equation shows that 1 molecule of CaCl2 reacts with 1 molecule of H2CO3 to form 1 molecule of CaCO3 and 2 molecules of HCl.
2Si +2HF-2siF + 2H
The coefficient of O2 is 5.The chemical equation is:C5H12 + 8 O2 = 5 CO2 + 6 H2O
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.
Cu + 2H2SO4 ==> CuSO4 + SO2 + 2H2OSo coefficient of CuSO4 is 1
