Sometimes, as during oxidation reactions oxygen is either added or hydrogen is removed from that particular element or compound undergoing the reaction. Combustion is burning taking place in the presence of oxygen so when the certain substance burns it is having oxygen added to it.
Eg. 2Mg + O2 gives 2MgO
Here Mg is getting oxidised and combustion is taking place as Mg is being heated in the presence of Oxygen.

∙ 14y agoNo! They are any type of reaction besides double-replacement. This includes:
Single-replacement, synthesis, decomposition, and combustion.
Wiki User
∙ 13y agoYes, all combustion reactions are redox reactions because elemental oxygen is a reactant.

∙ 12y agoyes.
ex:- C + O2 ----->CO2.
here oxidation state of C changes from +0 to +4, and that of O changes from +0 to -2.

∙ 8y agoNo, it is an oxidative breakdown reaction

Do all oxidation-reduction reactions have in common?
They both occur simultaneously in a redox reaction.
When an acid and an alkali react it is called combustion?
No. Acid + alkali reactions are neutralisation reactions. Combustion is a reaction with oxygen.
Why are combustion reactions considered exceptions to the rules of chemical reactions?
Combustion Reactions are always reacted with Oxygen gas in this case if you had C3H8+O2 you will ALWAYS get H2O+CO2 it does not matter if you have C100H54+O2 you will still get H2O+CO2 this is why combustion reactions are considered exceptions to the rules of a product or chemical reaction.
Is 2SO2 plus O2 equals 2SO3 a combustion reaction Why or why not?
Not a combustion reaction. Combustion reactions produce CO2 and H2O.
What is the overall voltage for a redox reaction with the half reactions Ag e Ag and Cu2 2e?
0.80-0.34
Which two reactions are also redox reactions combustion and single-replacement combustion and synthesis synthesis and decomposition single-replacement and double-replacement?
All of them can be redox reactions.
What two reactions are also redox reaction?
combustion and single-replacement
Is oxidation endothermic?
An oxidation reaction is also known as a redox reaction. Not all redox reactions give off heat. Some redox reactions give off heat and some require heat from an outside source for the reaction to be completed.
Where does Redox occur in bacteria?
The Redox 'Battlefield' is the Redox reactions mediated by bacteria.
Where does combustion happen in your body?
Everywhere if you refer to redox chemical reaction. Every organ uses redox reactions to transform something into something else. Brain for instance transforms glucose.
Is a combustion of coal an endothermic reaction?
NO ... all burning/combustion reactions are exothermic.
Are combustion reactions exothermic or endothermic?
All combustion is exothermic. ( i love pie)
The reactions taking place inside a lead accumulator are said to be redox reactions describe the chemical reaction and justify the statement?
redox reactions means which involves both oxidation and reduction reactions reactions.
In the redox reactions of cellular respiration a cell uses?
A cell uses both glucose and oxygen in the redox reactions of cellular respiration.
Do all oxidation-reduction reactions have in common?
They both occur simultaneously in a redox reaction.
Are single displacement and double displacement reactions always redox reactions?
A single displacement reaction is always a redox reaction, buta double displacement reaction is not a redox reaction.
What is the reactant compound in all combustion reactions?
For any combustion reaction O2 is required .
