Question

In a combination redox reaction, two or more compounds, at least one of which is a(n) compound, form a(n) products. General Reaction: X YZ → XZ Y. In a decomposition redox reaction, a(n) compounds forms two or more atoms (or ions), at least one of which is a(n) ion. General Reaction: Z → X Y In double-displacement (metathesis) reactions, such as precipitation and acid-base reactions, ____________ of two ____________ exchange places; these reactions ____________ redox processes. General Reaction: AB CD → AD CB In solution, single-displacement reactions occur when a(n) ____________ of one ____________ displaces the ____________ of another. Since one of the ____________ is a(n) ____________ , all single-displacement reactions ____________ redox processes. General Reaction: X Y → Z

Answer 1

Answer :

In double-displacement (metathesis) reactions, such as precipitation and acid-base reactions, the cations of two reactants exchange places; these reactions are not redox processes.

In solution, single-displacement reactions occur when an atom of one element displaces the atom of another. Since one of the reactants is an element, all single-displacement reactions are redox processes.

Explanation :

Double-displacement reaction : It is defined as the reaction in which the cation of two reactants molecule exchange their places to give two different products.

The double-displacement reaction are not a redox reaction.

It is represented as :

$AB+CD\rightarrow AD+CB$

Where A and C are the cations and B and D are the anions.

Single-displacement reaction : It is a type of reaction in which the more reactive metal displaces the least reactive metal from its solution.

It is represented as :

$A+BC\rightarrow AC+B$

Where A is the most reactive metal and BC is the compound in which the B is the least reactive metal which is displaced by the most reactive metal A.

The single-displacement reaction are a redox reaction.

Answer 2

Answer:

Here's what I get  

Explanation:

In double-displacement (metathesis) reactions, such as precipitation and acid-base reactions, the cations of two compounds exchange places; these reactions are not redox processes.

General Reaction: AB + CD → AD + CB  

In solution, single-displacement reactions occur when an atom of one element displaces the atom of another. Since one of the reactants is an element, all single-displacement reactions are redox processes.

General Reaction: X + YZ → XY + Z
