Arguments advanced for this lack of concern are that the average person with cardiac problems is too old to be concerned with sexual activity, or that persons with disabilities can not engage in secual intercourse or are not inclined to do so (Sidman, 1977).
When forest fuels burn, there is a chemical combination of the oxygen in the air with woody material, pitch and other burnable elements found in the forest environment. This process in known as Combustion. Combustion is a chain reaction chemically similar to photosynthesis in reverse. Photosynthesis requires a large amount of heat which is furnished by the sun. The Combustion process releases this heat.
COMBUSTION REACTION: Combustion of methane is an exothermic reaction in which a large amount of energy is liberated. Due to this property, methane is used as a domestic and industrial fuel. CH4 + 2O2 CO2 + 2H2O HALOGENATION: Replacement of halogen atom with H-atom of an organic compound is called Halogenation.It is a substitution reaction.This reaction occurs in the presence of sun light. It is a free radical mechanism eaction.ue to this property, methane is used as a domestic and industrial fuel.
