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 ...
Answer:For the rusting of iron, both water and oxygen are necessary. Jar A was filled with tap water which has dissolved oxygen in it, hence, on keeping an iron nail in this water, the nail gets rusted. Jar B contains boiled water, on boiling the dissolved oxygen is removed but as si...
The chemical formula for rust is Fe2O3 and is commonly known as ferric oxide or iron oxide. The final product is a series of chemical reactions simplified below as- The rusting of the iron formula is simply 4Fe + 3O2 + 6H2O→ 4Fe(OH)3.The rusting process requires both the elements ...
