Does rusting of iron require the presence of oxygen and water for it to occur?
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.
How much does oxide cost per gram?
It depends upon the nature and element (Other than oxygen) of oxide.
If 50g iron gets melted how much liquid iron gets produced?
if a 50 g of iron gets melted how much liquid does it produce
Sodium oxide melting point higher or lower than water?
Much higher. Water melts around 1 0C. At this temperature and much higher, sodium oxide is a solid.
What happens when Ag2CO3 is heated?
When burning the chemical, the powder darkens itself. At some point, during the reaction, some whitish smoke comes out. We could also notice a specific smell was given off during the reaction. CO2 is given off.
How much does each molecule of iron oxide contain?
The oxide Fe2O3 has: 70 % iron and 30 % oxygen.
What is the catalyst used in haber?
its an iron catalyst (iron oxide)
How can too much rust damage an object?
too much oxygen combines with the raw iron and forms iron oxide or rust. this weakens the iron and thus damages it.
How much does thermite cost?
Roughly $3 a pound It is a 1:3 ratio of aluminum oxide and black iron oxide (respectively, and is the best mix)
How much carbon is in pure iron?
If it is pure iron then by definition there is no carbon or anything else present in it, just iron.
Is iron oxide a mixture or a compound?
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
What happens when iron and oxygen combine to form rust?
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
Will a lead pipe rust?
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 calcium oxide can be present by heating calcium metal in oxygen How much calcium would be needed to make 15.0 g of calcium oxide?
If reaction is 100% completed then 16g Calcium produces 22.4g Calcium oxide.
Why does burnt iron weigh more than unburnt iron?
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!
Is it true that when iron react with oxygen it creates corrosion?
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.
Does iron react with potassium hydroxide?
no but you may find that an irish leprechaun will jump into your window to try and make it react with his pot of gold
