nothing it just rusts the metal
Oxidation. Water, oxygen, and metal.
well, when metal rusts, it sort of becomes weaker, and for example, the hinges on your door, it becomes squeaky when you open and close it
Well, when iron rusts, it's oxidizing, which means that it's reacting with the oxygen in the air, which causes it to break down and form rust (Fe2O3).
Metal rust will not harm trees. There are a number of fungus rusts that can harm plants but they are not metal rusts.
The rust is an oxide of the base metal.
Iron rusts in the presence of Oxygen.
When metal rusts by forming a solid metal oxide with oxygen from air, the rusted solid metal weighs more.
Yes it does!
Neither. Only iron rusts. Other metals oxidize.
