The rate or speed at which the reactants combine is high, in part because of the nature of the chemical reaction itself and in part because more energy is generated than can escape into the surrounding medium, with the result that the temperature of the reactants is raised to accelerate the reaction even more. Look at the chemical make-up of the substances after the change, and compare them with the chemical make-up before the change. Flames have a definable composition and a complex structure; they are said to be multiform and are capable of existing at quite low temperatures, as well as at extremely high temperatures. Answered Is combustion a physical or chemical process ? As has been pointed out, in any oxidation process the oxidizer takes electrons from the oxidizable substance, thereby itself becoming reduced (gaining electrons). Combustion is one of the most important of chemical reactions and may be considered a culminating step in the oxidation of certain kinds of substances.

Combustion or burning is the sequence of exothermic chemical reactions between a fuel and an oxidant accompanied by the production of heat and conversion of chemical species. If you are at an office or shared network, you can ask the network administrator to run a scan across the network looking for misconfigured or infected devices. Properly ignited, the heat from the flame raises the temperature of a nearby layer of the matchstick and of oxygen in the air adjacent to it, and the wood and oxygen react in a combustion reaction.

When equilibrium between the total heat energies of the reactants and the total heat energies of the products (including the actual heat and light emitted) is reached, combustion stops. Combustion is the scientific word for burning. The ability to Your IP: 220.127.116.11 1. Why don't libraries smell like bookstores?
