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 Reactions. A combustion reaction is when a substance reacts with oxygen and releases a huge amount of energy in the form of light and heat. A combustion reaction always has oxygen as one reactant. The second reactant is always a hydrocarbon, which is a compound made up of carbon and hydrogen. combustion reaction always includes a hydrocarbon and oxygen as the reactants and always produces carbon dioxide and water as products. Balancing combustion reactions is similar to balancing other types of reactions. First, balance the carbon and hydrogen atoms on both sides of the equation.
