metals and organic contaminants such as solvents‚ crude oil‚ explosives‚ and other toxic compounds from contaminated environments. Mechanism: Bioremediation works by taking complex organic compounds such as TNT‚ which are made up of carbon‚ nitrogen‚ oxygen‚ and hydrogen. When combined with regular compost ingredients such as manures‚ sawdust‚ straw‚ and fruit and vegetable processing wastes‚ the explosives become broken down into harmless chemical forms.(3) Bioremediation methods are classified

Humankind is largely fed by food grown with synthetic chemical fertilizer and by explosives like Dynamite. Synthetic fertilizer requires a plentiful supply of nitrogen‚ inventing a process to fix it in ammonia was daunting. Attempts were made for over 100 years. Then in 1909 Fritz Haber‚ a German chemist‚ solved the problem in principal. In 1910‚ Carl Bosch‚ pioneering new engineering methods‚ commercialized the process. Known as the Haber-Bosch Process‚ it is now responsible for growing about half

Experiment B10- Photocromism and Piezochromism Reece Harms 4320288 Introduction This experiment investigates an oxidative coupling reaction in an to synthesise triphenylimidazole dimer from 2‚4‚5-triphenyl-1H-imidazole. The resulting compound was investigated for both photochromic and piezochromic properties by way of formation of a stable radical‚ utilizing visual observations and UV-Vis as a means of distinction. Both the oxidative coupling reaction and the dimers interaction with light

one of the causes that can increase the effect of global warming. Air pollution is caused by certain gases which pollute the air such as carbon dioxide (CO2)‚ sulfur dioxide‚ methane‚ CFC (chlorofluorocarbons)‚ carbon monoxide (CO)‚ aerosol‚ and nitrogen dioxide. Some of these gases are already in the atmosphere; some are produced by human activities. To prevent the condition of the air from getting worse‚ there are some solutions we can do from now; small steps for a bigger change. This essay will

The Effects of Herbicides on Aquatic Organisms Anthony Cerda John Jay Science and Engineering Academy Abstract In this experiment different herbicides were added to aquatic organisms. The organisms used were protists and bacteria which are microscopic organisms (Microorganisms). Herbicides are chemicals used to control certain plants such as weeds. Two hypotheses were tested in the experiment.H₁) The herbicides will affect the population growth rate of the microorganisms and H₂) The adding

In order to release the nitrogen into soil‚ this polymer coating will be very effective. This product will send nitrogen for defined time and they use this product in manner so that‚ crops will intake particular amount of nitrogen at each stage of its growth. In more detail‚ this product is mainly designed to reduce the release of nutrient for the one month period after the single application in order to use the nitrogen supply effectively. The application of this product

Determine the empirical formula of the compound. (Ans: CH2) 6. A fuel mixture used in the early days of rocketry is composed of two liquids‚ hydrazine‚ N2H4‚ and dinitrogen tetraoxide‚ N2O4‚ which ignite on contact to form nitrogen gas and water vapor. Calculate the mass of nitrogen gas formed when 100 g of N2H4 and 200 g of N2O4 are mixed. (Ans: 131.148
