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).
