it is caused by a chemical reaction with metal and water
yes
Yes, if the dog tag metal is exposed to water for a prolonged period of time, it can rust. Rust forms on metal when it comes in contact with water and oxygen, causing corrosion over time. It is best to keep dog tags dry to prevent rusting.
Metal turns into rust when exposed to oxygen and moisture over time, a process known as oxidation. The oxygen in the air reacts with the metal's atoms to form a new compound, which appears as reddish-brown iron oxide, or rust. This process can be sped up by increasing the metal's exposure to water and oxygen.
Iron corrodes to form an iron oxide. This oxide is commonly called rust. The reaction involves a transfer of electrons from iron to oxygen. Water is commonly slightly acidic due to the carbon dioxide in the atmosphere. The acid brings hydrogen ions in contact with the iron which allows the formation of an iron hydroxide intermediary compound which hastens the formation of iron oxide, rust. Ships at the bottom of the ocean rust more slowly as there is less oxygen and the water is less acidic. The only way to prevent rust forming is to prevent oxygen coming in contact with the iron through the application of paint, oil, plastic or another metal.
Boiling water helps to remove dissolved oxygen which is necessary for the oxidation process that causes metal to rust. Without oxygen, the metal is less likely to react and form rust even when in contact with water.
Boiling water will not cause metal to rust. Rusting is a chemical reaction that occurs when metal is exposed to oxygen and moisture for an extended period of time, leading to the formation of iron oxide. Boiling water can, in fact, help remove rust from metal surfaces.
The oxygen in the water reacts with the metal in the nail - forming metal oxide (rust)
warm water will rust metal faster
Yes, it does.
Salt water does make nails rust faster than non-salted water, because when salt is added to water, it will rust the top layer of the nail, and then make the nail basically shed its top layer. Then the salt will rust that layer, and this process continues until the whole nail is rusted. Normal water can only really rust the top layer, and can't get to the rest of the nail.
Metal can start to rust in one day under the right conditions, such as high humidity or exposure to water. The speed of rust formation can vary depending on factors like the type of metal and the environment it is in.

Yes
yes
it is caused by a chemical reaction with metal and water
metal has a tendency to oxidize and water oxidizes the metal . oxidation leads to rust formation
