Q7.The balanced chemical equation for the rusting of iron is: 4Fe (s) + 3O2(g) → 2Fe2O3(s) How many atoms of each of Fe and O are there each on the reactants side and the products side? 4 Fe and 3 O2on the reactants side and 2 Fe and 1 O3on the products side. ...
Over time, iron develops a red, flaky coating called rust. This is anexample of an oxidation reaction. Other everyday examples include the formation of verdigris on copper and the tarnishing of silver. Here is thechemical equationfor the rusting of iron: Fe + O2+ H2O → Fe2O3. XH2O ...
When an iron object is left in damp air (or water) for a considerable time, it gets covered with a red-brown flaky substance called rust. This is called rusting of iron. During the rusting of iron, iron metal combines with the oxygen (of air) in the presence of water (moisture) to ...
