Parts of a car start to go rusty because of irons reaction with oxygen to form iron oxide. This reaction is helped along by water and road salts.
That depends on what effect is desired; If you like to breathe, it is a useful gas; If you prefer that your car (or whatever) not be rusty (oxidized), then it is a harmful gas.
Rusting is oxidation, a chemical reaction.
Yes. The rust on the penny indicates that a reaction between the penny and its environment has occurred. Since a new material was formed from this reaction (the rust) the reaction must be a chemical reaction.
If you expose iron to air then it gets rusty but it sure does take ime to get rusty.
perhaps your washing machine is slightly rusty. the water shouldn't be rusty. hope this helps x
