Is rusting a chemical process?
The equation when iron rusts is: 4Fe + 3O2 + 6H2O ---> 4Fe(OH)3 Explanation: Iron and oxygen and water react to form iron hydroxide. It can be more complicated with less pure substances but this is the general equation for rusting.

What rusts in water?

How long does it take for acid to rust metal?
It takes about 4-5 days. Iron rusts because it meets with oxygen ,It rusts faster in water than in acid because water has more oxygen.

When iron rusts is that a chemical or physical change?
It is a chemical change, the iron is being oxidized and forming rust. A good way to think about it is if you can undo it then it is a physical change. For example if you put salt in water, that is a physical change because you can boil off the water and get the salt back. Source: AP Chemistry
