All combustion reactions are redox reactions.
true or false

false

Explanation:

A combustion reaction is a burning process that occurs in the presence of an oxidant and a fuel. It is usually an energy releasing procedure in which the temperature of the environment is greater than that of the reactants.

Not all combustion reactions are redox reactions

In a redox reaction, one specie is oxidized and the other becomes reduced simultaneously.

Redox reactions are usually facilitated by the transfer of electron. One specie loses electrons to be gained by another specie.

Certain atoms in a combustion reaction will have to change their oxidation state.

During combustion, during combustion reaction, there is no transfer of electrons between reactants . None of the molecules changes oxidation state. For example;

   CH₄   +   2O₂       →    CO₂  +    2H₂O

The algebraic sum of all oxidation number of all atoms in a neutral compound is zero.

In the reaction above, all the atoms in going from reactants to products have a net oxidation number of zero.

carbon on both sides is 0

oxygen is 0

Hydrogen is 0

So there is no transfer electrons
