What is the metal element which is used to coat the outside of food cans?
The metal element used to coat the outside of food cans is typically tin. This coating is applied to prevent the metal of the can from interacting with the food inside, which can affect the taste and safety of the food.
Why do cans rust over time?
because cans are made out metal. metal has a chemical reaction to oxygen. [water has oxygen in it so thats why water rusts when with water] the property of chemical property this is is called reactivity.
Soda cans are made with this metal?
Aluminum is the metal commonly used to make soda cans because it is lightweight, durable, and easily recyclable.
What makes cans rust?
Cans rust when the metal coating on the surface of the can is damaged, allowing oxygen and moisture to come into contact with the metal. This leads to a chemical reaction where the metal (typically steel) oxidizes, forming iron oxide, which is commonly known as rust.
How could a recycling center separate a mixture of metal cans?
A recycling center can separate a mixture of metal cans using a magnetic separator. This machine uses magnets to attract and separate the metal cans from other materials in the mixture, such as plastic or paper. The metal cans are then further processed for recycling.
Why do tin openers have magnets if tin is non-magnetic?
Because it is a TIN coating on the inside of cans of food {today replaced by teflon/plastic} with the majority of metal comprising of steel.
What is the metal element which is used to coat the outside of food cans?
The metal element used to coat the outside of food cans is typically tin. This coating is applied to prevent the metal of the can from interacting with the food inside, which can affect the taste and safety of the food.
Why doesn't acidic food corrode a metal can before it's opened?
The inside of the cans have a protective coating that prevents or slows deterioration of the metal can by the acids in the food.
What metal used in drink cans that is often recycled?
copper because it isn't a very reactive metal ...... however gold is very least reactive but is is very expensive to buy so go with copper !fruit juice cans are either steel or aluminum, like any other can, but are coated on the inside surface with a thin layer of plastic to keep the metal from reacting to the juice.copper would be very bad as its reaction products are toxic!
Why do cans rust over time?

Why aren't cans made of pure tin?
Food cans are coated with tin instead of zinc because zinc is more reactive than tin. Tin is only reactive to powerful acids such as tri-sodium phosphate while zinc can be reactive to something like tomatoes.
Can zinc make cans?
Yes, zinc is commonly used to make cans because of its corrosion-resistant properties. The zinc is applied as a thin coating to protect the metal can from rusting and reacting with the contents inside. This process is known as galvanization and helps to prolong the life of the can.
Why does a aluminum drinks can not react with the contents?
Most soft drinks are slightly acidic, and aluminium is a very reactive metal -- E0 is -1.7 volt. Why, then, does the can not react with the contents?There are two reasons. Firstly, although aluminium is potentially very reactive, its first reaction is usually to form an impervious layer of aluminium oxide over the whole of its surface, and this ensures its inability to react further. Secondly, just to make sure, most aluminium drink cans are coated on the inside with a thin film of unreactive plastic.
Why is aluminium a good metal to use for drinks cans?
Aluminum is a good metal for drinking cans because it is light, easily obtained, non-toxic and it can be handled roughly.
Soda cans are made with this metal?
Aluminum is the metal commonly used to make soda cans because it is lightweight, durable, and easily recyclable.
What causes rust on cans of food?
Rust on cans of food is typically caused by the reaction of iron in the metal can with oxygen and moisture in the air. Damage to the lacquer coating or enamel lining of the can can accelerate the formation of rust. Ingesting rust from a can can be harmful, so it's important to discard any cans with rust on them.
What makes cans rust?
