How do you calculate percentage in iron oxide?
The percentage of iron oxide in iron oxide is ... yep, you guessed ... 100%!
What are two basic composition of laser toner and give their function?
Iron Oxide
What is a wüstite?
A wüstite is a grey mineral form of iron(II) oxide with a greenish tint.
Why does exposed surface of a cut brinjal become black?
because of d corrosion.....the constituent of the pulp(probably iron) reacts wid air to form iron oxide.....and the pulp turns black
1 kilogram of water is heated together with 1 kilogram of iron.Which would require greater amount of heat and why?
Iron would require a higher amount of heat due to the fact that it is a metal and has stronger bonds than water does. Water is made up of hydrogen bonds which allow it to heat up quickly.
Is it possible to use hydrogen as a reducing agent for ion oxide to get the metal iron?
No. On the contrary - iron will reduce hydrogen oxide to hydrogen
Iron oxide plus hydroflouric acid equals?
Iron Oxide+Hydrofluoric Acid --> Iron Fluoride + water For Iron II oxide: FeO+ 2HF --> FeF2 + H2O For iron III oxide Fe2O3 + 6 HF --> 2 FeF3+ 3 H2O Iron II,III oxide Fe3O4 + 8HF --> FeF2 + 2FeF3+ 4 H2O
Iron III oxide will decompose in the presence of hydrogen gas and heat to produce free iron and water?
Fe2O3 + 3H2 -----> 2Fe + 3H2O
What is the structure for iron oxide?
carbon,hydrogen,and oxgen
What happens when iron oxide is mixed with water?
Iron oxide (Fe2O3) in insoluble in water.
What happens to iron oxide when it is dissolved?
Iron oxide (Fe2O3) in insoluble in water.
Do iron oxide dissolve in water?
No- if it did, water would wash away rust (rust is iron oxide)
What does iron and water make?
Iron oxide or rust
What chemical combination of a substance with oxygen is?
This is called oxidation, i.e. when iron reacts with oxygen iron oxide is formed. Also, combustion could be included: methane + oxygen -> carbon dioxide + water
Can hydrogen and iron form rust?
No.It is oxygen that is the gas needed to turn metallic iron into iron oxide (otherwise known as rust). Water and some form of electrolyte are also required to perform the electrochemical reaction.
Is Iron III oxide soluble?
In water, no.
Word equation for rusting iron?
The word equation for the rusting of iron is: Iron+oxegen+water→hydrated iron oxide (rust)
