4,06 g Fe2O3 contain 2,842 g iron.
No. Only oxygen must be present. The process of rusting is the reaction of iron metal (Fe) combining with oxygen gas (O2) to form iron oxide (FeO or Fe2O3). Water (and salt) speed up this reaction a great deal, but oxygen is the only one that is necessary.
It depends upon the nature and element (Other than oxygen) of oxide.
if a 50 g of iron gets melted how much liquid does it produce
Much higher. Water melts around 1 0C. At this temperature and much higher, sodium oxide is a solid.
4,06 g Fe2O3 contain 2,842 g iron.
The oxide Fe2O3 has: 70 % iron and 30 % oxygen.
its an iron catalyst (iron oxide)
too much oxygen combines with the raw iron and forms iron oxide or rust. this weakens the iron and thus damages it.
Roughly $3 a pound It is a 1:3 ratio of aluminum oxide and black iron oxide (respectively, and is the best mix)
If it is pure iron then by definition there is no carbon or anything else present in it, just iron.
Pure iron oxide is a compound, but if there is something else mixed in with it, then of course it will become a mixture. There is more than one oxide of iron, though. Here are 2 types of iron oxide: Iron (II) Oxide is a black powder with a formula of FeO Iron (III) Oxide, also rust, is a brownish-red powder with a formula of Fe2O3
Nothing spectacular happens-- this is a chemical change. The useful properties of iron are destroyed when it rusts, so much is usually done to prevent rusting -- i.e painting. other coatings that prevent rust. If you can keep the oxygen away from the iron, it will not rust.Isn't it that it makes iron oxide? or is rust really iron oxide?--different person
Lead won't rust in the same way as iron, a white oxide layer will appear overtime, but it won't break away as much as rust on iron.
If reaction is 100% completed then 16g Calcium produces 22.4g Calcium oxide.
Because of the pressure that is on the the hot iron the cold iron doesn't have as much force as the hot one so that's why!
No, iron is naturally rusting under normal conditions, it isn't a noble metal. Iron differs from aluminum, for instance. The layer of aluminum oxide that forms on aluminum protects the underlying metal from further oxidation; rust does not have the same effect.
