Thanks for coming to the meeting everyone!
Today Marcus talked about basic oxidation. He showed a video about oxygen, which you can view here.
He used Potassium Chlorate (KClO3), which is a strong oxidizing agent, to oxidize sugar. This reaction is extremely exothermic, which resulted in the glowing light and intense heat produced.
During the meeting, Kunal said that this reaction is a combustion reaction. Although it is exothermic and produces carbon dioxide and water, it is not a combustion reaction in the strictest sense. Combustion reactions involve elemental oxygen as a reactant; this reaction did not.
On a side note, the other reaction mentioned, the rusting of iron in the presence of oxygen, is considered a combustion reaction, as it involves pure oxygen as a reactant.
4Fe + 3O2 -> 2Fe2O3
