1. Can you give me the details of all oxides of iron - its colour,formation,chemical equation,etc?

2. Can there be two or more products in a combination reaction? Give examples.

Expert Answer:

     Oxides of IRON:
     Fe(II) oxides
1) FeO
2) FeO2
    Fe(III) oxides:

Colour ranges from reddish to brown.



2. Yes, there is only one product is formed at the end of combination reactions.

Combination Reaction :

A chemical reaction in which two or more substances combine to form a single product is called a combination reaction or synthesis.

 When iron and sulphur are heated together, they combine to form a single product, iron sulphide.

                                   2Fe(s)     +     S(s)    →              FeS (s)

                                       Iron         Sulphur                Iron sulphide
