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.
No! They are any type of reaction besides double-replacement. This includes:
Single-replacement, synthesis, decomposition, and combustion.
Yes, all combustion reactions are redox reactions because elemental oxygen is a reactant.
(Silberberg, "Chemistry The Molecular Nature of Matter and Change" Fifth edition)
yes.
ex:- C + O2 ----->CO2.
here oxidation state of C changes from +0 to +4, and that of O changes from +0 to -2.
No, not necessarily, eg. rusting of iron is oxidation without fire
No, it is an oxidative breakdown reaction
Yes it is
They both occur simultaneously in a redox reaction.
No. Acid + alkali reactions are neutralisation reactions. Combustion is a reaction with oxygen.
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.
Not a combustion reaction. Combustion reactions produce CO2 and H2O.
0.80-0.34
All of them can be redox reactions.
combustion and single-replacement
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.
The Redox 'Battlefield' is the Redox reactions mediated by bacteria.
Everywhere if you refer to redox chemical reaction. Every organ uses redox reactions to transform something into something else. Brain for instance transforms glucose.
NO ... all burning/combustion reactions are exothermic.
All combustion is exothermic. ( i love pie)
redox reactions means which involves both oxidation and reduction reactions reactions.
A cell uses both glucose and oxygen in the redox reactions of cellular respiration.
They both occur simultaneously in a redox reaction.
A single displacement reaction is always a redox reaction, buta double displacement reaction is not a redox reaction.
For any combustion reaction O2 is required .
