Decomposition heating iron ii sulfate heptahydrate?
Up to cca. 480 0C iron(II) sulfate lost crystallization water; after this temprature the sulfate is decomposed in iron oxide and sulfur oxide.
What is the purpose of phosphoric acid in the synthesis of aspirin?
to serve as a catalyst and speed up the reaction
What 2 elements make up rust?
Iron and oxygen
Why does the surface of mars appear to be red?
Because it's surface is made up of mostly Iron Oxide (rust).
How were the heavy elements from iron to uranium made?
Up to uranium elements are made by stellar nuclear synthesis; after uranium elements are man made.
What is the main compound in rust?
The scientific name for rust is iron oxide. It is made up of the elements iron and oxygen. Turning iron to iron oxide is an example of corrosion.
What elements are in iron oxide?
We know that iron (Fe) and oxygen (O) make up iron oxide. (There is more than one oxide of iron, by the way.)
What makes up the planet Mercury?
It is made of iron oxide. It is made of iron oxide.
What is a product in this reaction Al O2 Al2O3?
It is a synthesis reaction because the two substances are combining to form one.
What is iron oxide made up of?
Iron oxide is made up of iron and oxygen combined together. There are three types of iron oxide viz., Iron(II) oxide (FeO) occasionally referred to as 'greenstone' , because it is slightly green in colour. Iron(III) oxide (Fe2O3) commerically referred to as iron ore. It is the most common and stable of the oxides of iron. Iron(IV)Oxide (Fe3O4) known as magnetite. Because a rod or bar of it will orientate towards the north pole. Historically it was named 'lodestone'.
Why is rust an element?
Rust is not an element. Rust is a compound which is made up of iron oxide.
Is iron oxide an element?
NO!!!! It is a COMPOUND. It is made up of two elements. viz. Iron(Fe) and oxygen(O).
What can you do to speed up the synthesis of iron oxide besides with water?
i dont think you can effect the rate determining step in that reaction. it is a very slow process. however temperature affects the rate of almost every reaction, aswell as concentration just water, perhaps a catalyst? not much else you can do for a solid.
What 2 substances contain iron?
No elements are made up of a compound. I think you mean 'Which elements make up iron oxide?', and the answer to that is iron and oxygen.
Why is iron oxide a catalyst for rocket candy?
Iron Oxide acts as a lower energy path for the reaction to occur. This speeds up the reaction.
Decomposition heating iron ii sulfate heptahydrate?
Up to cca. 480 0C iron(II) sulfate lost crystallization water; after this temprature the sulfate is decomposed in iron oxide and sulfur oxide.
What elements make up latter iron oxide?
Latter is not a specific stage or element name. Bulk or raw iron oxide has iron and oxygen in nonstoikiometric ratios between wustite, magnetite, hematite, and maghemite.
