if I will react Iron Oxide and Aluminum, an exothermic reaction will happen and from that iron will melt. But a question, where the energy is coming from? Is something vanishing from there?

[Borek]

As in every exothermic reaction, you replace a weak bond with a much stronger one.

[Burner]

Is something vanishing from there?

No. Mass is conserved in chemical reactions, except in radioactive decays.

[rohit sharma]

What is ratio of the matter is required to do it perfectly or you could say that means that no Iron oxide or Aluminum left?  

[Burner]

Write a balanced equation of thermite reaction first.

Its been a long time - so I do not remember exactly....  but can't you look up the bond energies of the products and of the reactants and the difference is the dH?

Possible to do a thermite reaction with indian coin made of Ferritic Stainless Steel?

Thermite requires iron OXIDE.

I think indian coins chromium. How do I convert it chromium oxide to react for thermite.

You've got three words right there. They are chromium in the coins, and chromium, and oxide that you need.  Can you guess what else you need?  Can you guess where to get it?

Hey sorry, I repeat. How do I convert chromium to chromium oxide.

Hey sorry, I repeat. How do I convert chromium to chromium oxide.

An Indian coin is not made just of chromium. It is an alloy which depends on the denomination. There are other substances added to it too. The reaction proceeds in powder form, therefore it is upto you- how you are going to powder a coin, separate the various metals and alloys from it while leaving the iron behind, and react it to produce iron oxide.(XD) You can't just make thermite at home with an "Indian Coin" and aluminium. You need iron oxide powder, mix it thoroughly with alumimium powder that you can buy. Insert a burning magnesium fuse in it to set off the reaction. The law of conservation of matter/energy says that matter/energy can neither be created nor destroyed. You need to look up or form a reaction on paper so that you can know the ratio in which things react. I advise you to learn more about reactions, chemistry, experiments,etc.
