In chemical equations, the number written before an element symbol represents the coefficient, which indicates the number of atoms or molecules involved. Thus, "3Fe" indicates 3 iron atoms, while "Fe3" would suggest an iron molecule containing 3 atoms. To properly balance an equation, coefficients are used to ensure the number of each type of atom is the same on both sides.
The balanced chemical equation for the reaction is: 3FeO4 + 8Al -> 4Al2O3 + 3Fe Therefore, the coefficient of Fe is 3.
The balanced equation is 2Fe2O3 + 4Al ----> 2Al2O3 + 3Fe. The coefficient of Fe is 3.
Fe3(PO4)2(aq) + 3AgNO3(aq) --> Fe(NO3)2(aq) + Ag3PO4(s)
Zn2 + Fe3NO3 -> Zn3NO2 + Fe3
The reaction between Fe3+ and NaOH results in the formation of iron(III) hydroxide, Fe(OH)3, and sodium ions. The balanced chemical equation for this reaction is 2 Fe3+ + 6 OH- → 2 Fe(OH)3. This precipitation reaction forms a brownish precipitate of iron(III) hydroxide.
The balanced chemical equation for the reaction is: 3FeO4 + 8Al -> 4Al2O3 + 3Fe Therefore, the coefficient of Fe is 3.
iron(II) hydroxide + phosphoric acid 3Fe(OH)2 + 2H3PO4 => Fe3(PO4)2 + 6H2O
3Fe (s) + Al2(SO4)3 (aq) → 3Fe(SO4) (aq) + 2Al (s)
The balanced equation is 2Fe2O3 + 4Al ----> 2Al2O3 + 3Fe. The coefficient of Fe is 3.
Ferric acetate is the name of (CH3COO)3Fe.
Fe3O4 is the mineral magnetite, with aproper chemical name of Fe(II, III) oxide. it exhibits ferrimagnetism. It has iron atoms as FeII and FeIII. An old way of writing it was FeO.Fe2O3 The balanced equation for production from the elements is :- 3Fe + 2O2 -> Fe3O4 Commercially it is made by for example redung Fe2O3 with CO 3Fe2O3 + CO = 2Fe3O4 +CO2
Fe3(PO4)2(aq) + 3AgNO3(aq) --> Fe(NO3)2(aq) + Ag3PO4(s)
Zn2 + Fe3NO3 -> Zn3NO2 + Fe3
The reaction between sodium thiosulfate (Na2S2O3) and iron(III) nitrate (Fe(NO3)3) results in the formation of iron(III) thiosulfate and sodium nitrate. The balanced chemical equation for the reaction is: 2Na2S2O3 + 3Fe(NO3)3 → 3Fe(S2O3)2 + 4NaNO3
The reaction between Fe3+ and NaOH results in the formation of iron(III) hydroxide, Fe(OH)3, and sodium ions. The balanced chemical equation for this reaction is 2 Fe3+ + 6 OH- → 2 Fe(OH)3. This precipitation reaction forms a brownish precipitate of iron(III) hydroxide.
Ferric = Iron(III) = Fe3+
The molar mass of Fe3 is 167.5356 ± 0.0003 g/mol
