yes
iron reacts with air to form rust
4Fe(s) + 3O2(g) ===> 2Fe2O3(s)
The rusting of iron is given by the balanced equation:4Fe + 3O2 --> 2Fe2O3
4 Fe+ 3O2 + 6 H2O 4 Fe(OH)3 2 Fe2O3 + (x)H2OThis means that water doesn't actually react, but is necessary to perform the reaction and comes out as it is.
Designation of four-iron
Assuming you mean 2FeO3+3C ---> 4Fe+3CO2, yes, it is balanced.
4 Iron atoms + 3* Oxygen molecules + 6 Water molecules *Oxygen is diatonic, i.e. it only hangs around in pairs.
The balance equation would be 4Fe + 3O2 ==> 2Fe2O3, so the coefficients are 4, 3, 2.
yes
4Fe + 3O2 -> 2Fe2O3
4Fe + 3O2 --> 2Fe2O3
2(Fe2O3)+3C ==> 4Fe + 3CO2
4Fe + 3O2 2Fe2O3
No, it is the oxidation of iron (4Fe(s) + 3O2) to form iron oxide(2Fe2O3).
A basic equation for the formation of rust is 4Fe + 3O2 --> 2Fe2O3
Oxygen air. 2Fe + O2 -> 2FeO or 4Fe + 3O2 -> Fe2O3
