Types of Chemical Reactions and the Given Transformations

Chemical reactions involve the transformation of reactants into products. There are several types of chemical reactions, including synthesis, decomposition, single displacement, double displacement, combustion, and redox reactions. Let's analyze the given transformations and identify the types of chemical reactions involved.

1. H2O → O2: This transformation involves the breakdown of water (H2O) into oxygen gas (O2). It can be classified as a decomposition reaction, where a compound breaks down into simpler substances. The reaction can be represented as:

   2H2O → 2H2 + O2
   

The decomposition of water is an example of an endothermic reaction, as it requires energy input to break the bonds within the water molecule.

2. O2 → FeO: This transformation involves the formation of iron(II) oxide (FeO) from oxygen gas (O2). It can be classified as a synthesis reaction, where two or more substances combine to form a single compound. The reaction can be represented as:

   2Fe + O2 → 2FeO
   

The synthesis of iron(II) oxide is an example of an exothermic reaction, as it releases energy during the formation of the compound.

3. FeO: The given transformation only mentions FeO, which is iron(II) oxide. However, it does not specify any reaction or transformation involving FeO. If you provide more information or context, I can help you further.

In summary, the given transformations involve a decomposition reaction (H2O → O2) and a synthesis reaction (O2 → FeO).
