The types of reaction that commonly produce more than one compound is to be determined. Concept introduction: A redox reaction is a type of reaction that involves the change in oxidation number of a molecule, atom or ion changes due to the transfer of an electron from one species to another. The redox reaction can be classified into three types depending upon the number of reactants and products as follows: 1. Combination redox reaction 2. Decomposition redox reaction 3. Displacement redox reactions Combination redox reactions are the reactions in which two or more reactants combine to form a single product. In displacement redox reactions, substances on both sides of the equation remain the same but the atoms exchange places in order to form the product while in decomposition reaction, one compound decomposes to form one or more product. A combustion reaction is a reaction in which reactant is reacted with molecular oxygen to form the product. Heat is released and the energy is produced in the reaction. Molecular oxygen is employed as an oxidizing agent in these reactions.

Interpretation Introduction
Interpretation:
The types of reaction that commonly produce more than one compound is to be determined.
Concept introduction:
A redox reaction is a type of reaction that involves the change in oxidation number of a molecule, atom or ion changes due to the transfer of an electron from one species to another.
The redox reaction can be classified into three types depending upon the number of reactants and products as follows:
1. Combination redox reaction
2. Decomposition redox reaction
3. Displacement redox reactions
Combination redox reactions are the reactions in which two or more reactants combine to form a single product. In displacement redox reactions, substances on both sides of the equation remain the same but the atoms exchange places in order to form the product while in decomposition reaction, one compound decomposes to form one or more product.
A combustion reaction is a reaction in which reactant is reacted with molecular oxygen to form the product. Heat is released and the energy is produced in the reaction. Molecular oxygen is employed as an oxidizing agent in these reactions.
