Question

Consider the following equation of the chemical reaction of a metal M:

\[\ce{4M + 3O2 -> 2M2O3}\]

This equation represents:

पर्याय

• combination reaction as well as reduction reaction.

• decomposition reaction as well as oxidation reaction.

• oxidation reaction as well as displacement reaction.

• combination reaction as well as oxidation reaction.

Answer 1

Combination reaction as well as oxidation reaction.

Explanation:

This is a combination reaction because two distinct reactants (metal M and oxygen O₂) fuse together to form a single product (M₂O₃). It is simultaneously an oxidation reaction because the metal M gains oxygen atoms (and loses electrons) to form its oxide.
