Combination reaction in which both the reactants are elements has to be classified as redox, non-redox reactions. Concept Introduction: Redox reactions: It is a type of reaction in which both oxidation and reduction happens simultaneously. One get oxidized and one get reduced. Example: Zn(s)+2H + (aq) → Zn 2+ (aq)+H 2 (g) Oxidation of Zinc increased by two and Hydrogen reduced by one; Zn is oxidized and hydrogen is reduced here. Non Redox reactions: In the reaction in which the oxidation state of both reactants and products remains the same. No reduction and oxidation occurs in this reaction. Example: NaOH+HCl → NaCl+H 2 O Oxidation state of each element remains the same. Combination Reactions: It is a type of chemical reaction in which two or more reactants combine to form a single product It is also known as synthesis reactions. Example: 2Na(s)+Cl 2 (g) → 2NaCl(s)

Solution Summary: The author explains that a combination reaction in which both reactants are elements has to be classified as redox, or non-Redox reactions.
Definition Definition Chemical reactions involving both oxidation and reduction processes. During a redox reaction, electron transfer takes place in such a way that one chemical compound gets reduced and the other gets oxidized.

Interpretation Introduction
Interpretation:
Combination reaction in which both the reactants are elements has to be classified as redox, non-redox reactions.
Concept Introduction:
Redox reactions:
It is a type of reaction in which both oxidation and reduction happens simultaneously. One get oxidized and one get reduced.
Example:
Zn(s)+2H+(aq)→Zn2+(aq)+H2(g)
Oxidation of Zinc increased by two and Hydrogen reduced by one; Zn is oxidized and hydrogen is reduced here.
Non Redox reactions:
In the reaction in which the oxidation state of both reactants and products remains the same. No reduction and oxidation occurs in this reaction.
Example:
NaOH+HCl→NaCl+H2O
Oxidation state of each element remains the same.
Combination Reactions:
It is a type of chemical reaction in which two or more reactants combine to form a single product
It is also known as synthesis reactions.
Example:
2Na(s)+Cl2(g)→2NaCl(s)

Interpretation Introduction
Interpretation:
Combination reaction in which the products are all elements has to be classified as redox or non-redox reactions.
Concept Introduction:
Redox reactions:
It is a type of reaction in which both oxidation and reduction happens simultaneously. One gets oxidized and one gets reduced.
Example:
Zn(s)+2H+(aq)→Zn2+(aq)+H2(g)
Oxidation of Zinc increased by two and Hydrogen reduced by one; Zn is oxidized and hydrogen is reduced here.
Non Redox reactions:
In the reaction in which the oxidation state of both reactants and products remains the same. No reduction and oxidation occurs in this reaction.
Example:
NaOH+HCl→NaCl+H2O
Oxidation state of each element remains the same.
Combination Reactions:
It is a type of chemical reaction in which two or more reactants combine to form a single product
It is also known as synthesis reactions.
Example:
2Na(s)+Cl2(g)→2NaCl(s)

Interpretation Introduction
Interpretation:
A decomposition reaction in which all reactants and products are compounds has to be classified as redox or non-redox reactions.
Concept Introduction:
Redox reactions:
It is a type of reaction in which both oxidation and reduction happens simultaneously. One gets oxidized and one gets reduced.
Example:
Zn(s)+2H+(aq)→Zn2+(aq)+H2(g)
Oxidation of Zinc increased by two and Hydrogen reduced by one; Zn is oxidized and hydrogen is reduced here.
Non Redox reactions:
In the reaction in which the oxidation state of both reactants and products remains the same. No reduction and oxidation occurs in this reaction.
Example:
NaOH+HCl→NaCl+H2O
Oxidation state of each element remains the same.
Decomposition Reactions:
It is a type of chemical reaction in which a single reactant breaks down to give two or more products. This reaction is opposite to Synthesis reaction.
Example:
CaCO3→CaO+CO2
Calcium carbonate is decomposed to give Calcium carbonate and Carbon dioxide.

Interpretation Introduction
Interpretation:
In Combustion reaction CO2 and H2O are the products has to be classified as redox or non-redox reactions.
Concept Introduction:
Combustion Reaction:
It is a type of reaction in which oxygen is one of the reactant. It will involve the evolution of heat and light. A hydrocarbon mainly undergoes combustion reaction. In case of hydrocarbons carbon dioxide and water will be the product.
