Iron is an element on the periodic table of elements. This means that iron is not made up by other atoms, but is a kind of atom itself.
A change of one substance in a material to a different substance is a?
You're thinking of a chemical change, a process by which you get a form of matter that you didn't have before. It's not really accurate to think of it as changing one substance into another. That sounds too much like alchemy, which is a pseudo-science. Rather, you simply rearrange the matter you had before into a new form, kind of like disassembling a Lego sculpture and reassembling a new one using the same old pieces.
What is the purpose of blowing oxygen into molten iron?
Blowing into molten cast iron causes the oxygen(02) to react with the carbon thus forming carbon dioxide. This is then bubbled away as the temperature is close to 20000 Celsius, this energizes the the gas which causes it to rise.
Why don't coins rust?
In common terminology rust is a form of iron oxide and occurs only when a ferrous metal such as iron or steel is exposed to air and moisture. The majority of coins issued around the world are instead made of metals that aren't subject to rusting; e.g. nickel, copper, aluminium, etc. Some countries, though, make coins from ferrous metals because they're less expensive than non-rusting alternatives. In these cases the steel is plated or bonded with some kind of non-ferrous metal (usually nickel or copper) to prevent direct air contact.
What kind of chemical reaction is waterfall?
A waterfall is not a chemical reaction.
What kind of change of rusting of iron?
Iron rusting is a chemical change in which iron reacts with moist air to form fe2o3 commonly known as rust, a brown coloured coating.
What kind of change iron to rust?
Iron rusting is a chemical change in which iron reacts with moist air to form fe2o3 commonly known as rust, a brown coloured coating.
What kind of change happen to a rusting of iron?
A chemical change, redox reaction: 2Fe(s) + O2(g) --> 2FeO(s)
Why is rusting a chemical change?
Rusting is a reaction which combines molecules to form other molecules: metal + oxygen -> rust. The definition of a chemical reaction is molecules turning into other molecules, so rusting is a chemical reaction.
What is one kind of an atom used to protect iron atoms from rusting?
Cobalt and Thorium
Why do you apply paint to iron articles?
Paint can protect iron from rusting, especially if it is the right kind of paint - you would not want to use a water based acrylic paint, since the water in the paint would promote rusting, rather than preventing it.
What kind of weathering causes iron?
physical weathering
What kind of changes causes iron to rust?
