Where is the thermit reaction used?
The thermite reaction usually has two reactants: Iron III oxide (Fe2O3, rust) and aluminum. Both reactants are in powdered form. The reaction is exothermic (heat is given out) The reaction equation is: Fe2O3 + 2Al --> Al2O3 + 2Fe The products are aluminum oxide (corundum) and molten iron.
What are examples of common everyday use of displacement reactions?
A double displacement reaction is one in which two reactants produce react to form two or more new products. Some examples of these reactions are the reaction of hydrochloric acid and sodium hydroxide, or of copper sulfate and barium chloride. Another double displacement reaction is the mixture of baking soda and acetic acid that give the products sodium acetate and carbonic acid.
What substance can be used to stop enzyme reaction?
prohibitors are used to enzyme reaction
What is wolfkrishner reduction reaction?
Wolff-Kishner reaction is used in order to reduce a ketone to an alkane. NH2NH2 (hydrozine) and KOH are used in the reaction.
What are the various reagents which can be used for Sandmeyer's reaction?
Sandmeyer's reaction is used to create aryl halides from dazonium salts. Any of the various copper salts are able to be used for this reaction.
What is the thermit reaction and how is it used to end broken railway lines?
No, she is 13 years old. Her birthday is August 25,1998.
What type of steel is used in the making of railway lines?
C-Mn steel
Why is iron used for railway lines?
Iron is rarely used anymore in railway lines. Steel is used mostly now because it is very flexible and is less vulnerable to cracking and chipping.
Why are solids used for railway lines?
They are used so that the railway track doesn't compress or move, and stay's the same so the train doesn't squash the track.
Which metal is used to mend railway tracks?
The key element in railway lines depending on the railway line is, occasionally copper, magnesium and stainless steel.

Are railway tracks and railway lines the same?
No. Railway tracks are only the rails and ties/sleepers and hardware used to hold the track in place. A railway line is a set of tracks designed to move a train between at least 2 points. A railway line can consist of many tracks.
When aluminium and iron oxide react together one of product is iron what is the formula?
You are looking at the thermite reaction, often used to weld into place railway lines (or if you are in america railroad tracks), which is the reduction of Iron (Fe) oxide with aluminium (Al) powder. The formula for the reaction is;2 Al + Fe2O3 -->2 Al2O3 + 2 Fe
What iron is used in making railway lines?
Iron is iron . . . but rails are made of high-strength steel. (Which is made from iron.)
Can i take railway service from Mexico city to Tennessee in the usa?
No. Most rail lines in Mexico are used for cargo movement (no passengers).
How is aluminium metal extracted by thermite process?
the reaction of iron(iii)oxide (Fe2O3) with alumimium is used to join the railway tracks or cracked machine parts. the reaction is known as ALUMINO THERMIT PROCESS. REACTION :- Fe2o3(s)+2Al(s) --> 2Fe(l)+Al2O3(s)+Heat -by kartikcool.cool@gmail.com
