Fe + O2 .............. Fe2O3.. We can see that iron reacts with atmospheric air to form iron oxide, called rust. hence weight is increase

Due to rusting there will be formation of iron oxide on the surface of iron nail and it will desentigrate so weight should be loss.

Rust is nothing but hydrated ferric oxide.fe react with atmospheric air and moisture to form fe2o3 thus it increase its weight

Rusting is the phenomenon of the continuous disintegration of the surface layer of the metal. ? means weight loss!

Iron is in its purest form is of a certain weight, but when oxygen gets added in it, iron gets additional weight.

When iron nail is rusted then it should be decrease his wright by decreasing there density. I think so.

When oxygen reacts with iron then form iron oxide and weight increase by adding of oxygen with Fe.

Because during the formation of rust iron reacts with oxygen&hence the weight increases.

Rust composed of iron and oxygen, that's why its weight is increased as compared to iron.
