CO2 + 4H2 O (Naphthalene) Combustion Introduction of the Product: Naphthalene is an organic compound with formula C10H8. It is the simplest polycyclic aromatic hydrocarbon‚ and is a white crystalline solid with a characteristic odor that is detectable at concentrations as low as 0.08 ppm by mass. As an aromatic hydrocarbon‚ naphthalene’s structure consists of a fused pair of benzene rings. It is best known as the main ingredient of traditional mothballs. Explanation: It’s formed

mixture is directed at the rock to release the gas inside. Hydraulic fracturing is the most popular method of exploitation of gas and oil from shale formations. After discovering hydraulic fracturing it has become possible at all production of hydrocarbons from unconventional deposits. Despite the many advantages of hydraulic fracturing raises a lot of controversy among consumes a considerable amount of water needed for the treatment.

cost considerations Jatropha oil‚Karanja oil‚Crude Palm Oil and Palm oil Stearin are being used as raw material to manufacture biodiesel. Biodiesel is safe‚ biodegradable‚ and reduces serious air pollutants such as particulate‚ carbon monoxide‚ hydrocarbons‚ and air toxic. Blends of 20% biodiesel with 80% petroleum diesel (B20) can generally be used in unmodified diesel engines. Biodiesel can also be used in its pure form (B100)‚ but it too may require certain engine modifications to avoid maintenance

A large number of chemicals may interact directly with DNA. However‚ many such as PAHs‚ aromatic amines‚ benzene are not necessarily mutagenic by themselves‚ but through metabolic processes in cells they produce mutagenic compounds. Reactive oxygen species (ROS) - These may be superoxide‚ hydroxyl radicals and hydrogen peroxide‚ and large number

Fracking is a contemporary method of extracting oils and gases that has become quite the vexation for many societies around the world. Fracking is the process in which liquid is injected at a high-pressure rate into different forms of rocks in order to forcefully open exiting fissures in order to extract oils or gases. During this process‚ water‚ sand and chemicals are inserted into the rock at high pressure; this part of the process allows the gas to flow to the head of the well and outward. Geological
