compounds can be classified as hydrocarbons and hydrocarbon derivatives on the basis of their hydrogen replacements by other elements or by other group of elements (functional group).All hydrocarbons are insoluble in water because of their relatively non-polarity and easily distribute. When hydrocarbons burn using oxygen‚ C02 and H20 are the sole products. There are 2 large classes of Hydrocarbon namely: unsaturated and saturated hydrocarbons.Unsaturated hydrocarbons contains one or more carbon-carbon

response - Clinically‚ epinephrine plays a lifesaving role in countering the effects of anaphylactic shock. It relaxes smooth muscle‚ though at different receptors. Physical Properties: - high boiling points and melting points compared to hydrocarbons of similar size -water soluble as it is small in size - the above characteristics can be explained by two types of polar bonds in all amines ‚ the N—C bons and any N—H bonds. Due to these bonds‚ the intermolecular

cracking process requires detailed qualitative and quantitative analysis of the hydrocarbon composition of its oil and fraction. In this analysis‚ their fractional composition‚ saturated vapor pressure‚ density and antiknock rating will be investigated. By knowing the qualitative and quantitative composition of the gasolines‚ the content of n-paraffin‚ isoparaffin‚ aromatic‚ naphthene‚ and olefin (PIANO) groups of hydrocarbons as well as of oxyorganic compounds (alcohols and ethers) used to raise the

temperatures‚ so their macromolecular structures are broken down into smaller molecules and a wide range of hydrocarbons are formed. These pyrolytic products can be divided into a gas fraction‚ a liquid fraction consisting of paraffins‚ olefins‚ naphthenes and aromatics‚ and solid residues. Pyrolysis appears to be a technique that is able to convert waste plastics into gasoline-range hydrocarbons [1]. There are four major methods for conversion of organic wastes to synthetic fuels: (1) hydrogenation

Unlocking the Secrets of the Universe Increasing our knowledge of Physics‚ using the scientific method to make observations and test hypotheses is essential to unlocking the secrets of the universe. Energy is one of the most fundamental elements of the universe. Throughout history‚ man has endeavored to expose‚ understand‚ and explain how and why things work. This drive to expand our understanding eventually led to the development of the scientific method and what is commonly considered
