Combustion
Combustion is a chemical process where a substance quickly reacts with a oxidant
Oxidant is a substance that accepts electrons from other substances
Combustion mostly occurs with oxygen as it is highly electronegative, to produce heat and light
The process in which a substance reacts with oxygen is basically combustion, this process is a exothermic reaction because energy is released when a bond is made due to low activation energy
Example Of Combustion
Burning wood in a fire place is a example
C6H12O6 + 6O2 = 6CO2 + 6 H2O
Oxidation And Reduction
Oxidation is a process where a substance releases electrons
Reduction is quite opposite to oxidation as it gains electrons
Electron Transfer: Redox reactions are fundamentally about the transfer of electrons between atoms, ions, or molecules.
Oxidation (Loss of Electrons): When an atom loses electrons, it's undergoing oxidation. This often results in an increase in its oxidation number (or a decrease in its negative charge).
Reduction (Gain of Electrons): When an atom gains electrons, it's undergoing reduction, leading to a decrease in its oxidation number (or an increase in its negative charge).
