4Fe + 3O2 --------> 2Fe2O3 so there are 3 oxygen molecule reacatnts and thus 6 oxygen atoms in the reactants.
There are two compounds present on the reactant side of the chemical equation: iron (Fe) and oxygen (O2).
The balanced chemical equation for the formation of Fe2O3 from Fe and O is: 4Fe + 3O2 -> 2Fe2O3
The chemical reaction for rusting steel is: 4Fe (s) + 3O2 (g) -> 2Fe2O3 (s). This equation shows that iron reacts with oxygen in the presence of water to form iron oxide (rust).
4Fe + 3O2 --> 2Fe2O3
The balance equation would be 4Fe + 3O2 ==> 2Fe2O3, so the coefficients are 4, 3, 2.
There are two compounds present on the reactant side of the chemical equation: iron (Fe) and oxygen (O2).
The balanced chemical equation for the formation of Fe2O3 from Fe and O is: 4Fe + 3O2 -> 2Fe2O3
No, the chemical equation is not balanced. It should be: 2Fe2O3 + 3C -> 4Fe + 3CO2.
The chemical reaction for rusting steel is: 4Fe (s) + 3O2 (g) -> 2Fe2O3 (s). This equation shows that iron reacts with oxygen in the presence of water to form iron oxide (rust).
The formula for iron (III) oxide is FeCl3, whether the formula is in a balanced equation or anywhere else where the formula is properly used.
4Fe + 3O2 --> 2Fe2O3
The rusting of iron is a chemical change, where iron and oxygen are the reactants and rust is the product. The basic equation for this reaction is: 4Fe + 3O2 --> 2Fe2O3
The balance equation would be 4Fe + 3O2 ==> 2Fe2O3, so the coefficients are 4, 3, 2.
The chemical equation for the reaction of iron with oxygen to form rust is 4Fe + 3O2 -> 2Fe2O3.
The chemical symbol for iron is Fe and for oxygen is O.
Isn't moisture also involved in it? so shouldn't H2O be a reactant also? EDIT: Yes, water (H2O) is required, but since the amount of H2O is the same on each side of the equation, it is not included in the chemically balanced equation. (Dr.J.)
The equation 2H2 + O2 -> 2H2O obeys the law of conservation of mass. This balanced chemical equation shows that the total mass of the reactants (hydrogen and oxygen) equals the total mass of the products (water).
