If you are not a welder or fabricator or have a good friend who is one then yes get rid of it before it falls apart at a really bad moment. It can be mended however depanding on the severity and the extent of the rust problem by a qualified tech.
iron bending different from iron rusting
Physical Changes in metal are: melting bending and rusting
yes. rust is a chemical change that occurs when you mix iron, air, and water. it reacts with the iron and actually erodes it. a n example of a physical change would be the bending or cutting of iron.
because it compromises the integrity of the structure that is rusting...
Rusting is a chemical property because it is irreversible. It changes the identity of the substance.
rusting and transmutation are the same because they are both dense. Therefore the attractive forces are determined by the air around it affects its rusting and transmutation.
rusting of iron is faster in rainy days because water is responsible for the rusting of iron i.e the presence of oxygen
Because the rusting of iron is based on a chemical change, a reaction of oxydation.
Because there is no water
O2 is necessary for the rusting because the iron forms an iron oxide complex with the oxygen. Fe (s) + O2 (g) --> Fe2O3 (s)
It creates microscopic 'cracks' in the surface - allowing moisture to penetrate deeper than it would normally. Therefore the metal rusts from the inside out.
Rusting is a chemical change because the metal is reacting with air and changing into a new substance.
