4 Iron atoms + 3* Oxygen molecules + 6 Water molecules
*Oxygen is diatonic, i.e. it only hangs around in pairs.
4Fe + 3O2 --> 2Fe2O3
The balanced chemical equation for the rusting of iron is: 4Fe + 6H2O + 3O2 -> 4Fe(OH)3
C2H5OH + 3O2 --> 2CO2 + 3H2O Ethanol + Oxygen --> Carbon Dioxide + Water
The chemical name for 3O2 is oxygen gas.
This is a balanced chemical equation for the combustion of ethanol (C2H5OH) in the presence of oxygen (O2) to form carbon dioxide (CO2) and water (H2O): C2H5OH + 3O2 → 2CO2 + 3H2O
4Fe + 3O2 --> 2Fe2O3
Hydrated Iron (III) oxide: 2Fe + 1.5O2 + xH2O -> Fe2O3·xH2O where x is the number of H2O molecules present.
...+13o2
The balanced chemical equation for the rusting of iron is: 4Fe + 6H2O + 3O2 -> 4Fe(OH)3
endothermic
No, the balanced equation is 6Ca + 3O2 ---> 6CaO. The product, calcium oxide, is CaO and not CaO2.
This is an oxidation-reduction reaction.
2Ca + 3O2 + 2C -> 2CaCO3
C2H5OH + 3O2 --> 2CO2 + 3H2O Ethanol + Oxygen --> Carbon Dioxide + Water
No. If you mean 4Al3O2. And If you mean 4Al + 3O2 ------> AL2O, it is still not balance.
Combustion of Ethane: 2C2H6+7O2-->4CO2+6H2O Combustion of Ethanol: C2H5OH+3O2-->2CO2+3H2O
The reaction 2KClO3 --> 2KCl + 3O2 is a decomposition reaction, where a single compound breaks down into two or more simpler substances.
