Cars: past‚ present & future Throughout the history of the automobile‚ there has been one factor that has determined its evolution. That factor‚ quite simply‚ is innovation. Every once in a while‚ there comes along a car that is so revolutionary‚ and has features so unique that the entire industry soon follows. This paper will help u understand how this process works‚ but to help you understand better ill take u back to when cars came from thought to reality ‚ then I’ll show u how far we have

module‚ xxxx. 2. Body 2.1 What melamine is and its uses According to World Health Organisation (WHO)‚ melamine is an organic base compound that is mostly found in the form of white crystals. With high nitrogen content‚ melamine has more than 5 times nitrogen compared to proline‚ a type of amino acid commonly found in milk. Being a relatively cheap industrial material that is durable‚ relatively non-toxic and water-soluble‚ melamine is used to make utensils‚ dishware and resins

nitrified into nitrite (NO2-) or nitrate (NO3-) by nitrifying bacteria‚ releasing H+ ions into the soil (3‚ 4). If not taken up by biomass and converted to methane‚ the surplus H+ ions eventually lead to the formation of an acidic soil environment. The nitrogen left over in the soil will either be taken up by plants‚ stored in the soil‚ returned to the atmosphere‚ or will be removed from the soil in runoff or leaching (3).

to positive metal ions because it loses electrons. But nitrate ions are also easily reduced to products like nitrogen monoxide and nitrogen dioxide. So metals reacting with nitric acid tend to give oxides of nitrogen rather than hydrogen. If the acid is relatively dilute‚ you tend to get nitrogen monoxide‚ although this immediately reacts with oxygen in the air to make brown nitrogen dioxide. Concentrated nitric acid gives

10−4 to 10−6). This basicity is due to the unshared electron pair on the nitrogen atom. Classification and nomenclature of amines Amines are classified as primary‚ secondary‚ or tertiary based upon the number of carbon-containing groups that are attached to the nitrogen atom. Those amine compounds that have only one group attached to the nitrogen atom are primary‚ while those with two or three groups attached to the nitrogen atom are secondary and tertiary‚ respectively. In the common

this process‚ he converted nitrogen of the air into potassium nitrate. Then‚ he removed the oxygen excess‚ but there still remained a small amount of gas‚ no larger than 1/120 of the original volume of air. He considered that this difference had been caused by experimental errors. About 100 years later‚ Lord Rayleigh and Sir William Ramsey discover Argon in 1894. For Ramsey‚ it is was as early as 1885-1890 when he published several notable papers on the oxides of nitrogen and followed those up with
