Almost everything in our world has some of their origins from chemicals‚ scientists in the chemical industries are always working to find ways to make these chemicals useful to us‚ they bring improvements into daily use substances like paints‚ medicines‚ cosmetics and plastics‚ so that they are more environmentally sustainable‚ and efficient. Scientists employed in the chemical industry trained and specialising in chemistry are called chemists. A chemist can gain expertise in a range of chemistry

plants that require fertilizers for the development of their roots‚ and Phosphorus fertilizers are the ones who have this ability. On the other hand‚ Nitrates or Nitrogen fertilizers in an excessive concentration would give an excessive amount of proteins to the duckweeds which would not be needed by them and hence concentrated nitrogen won ’t be that helpful for their growth. Tap Water would also be a good fertilizer for the duckweeds since it contains sufficient nutrients and hence would help in

The author of the advertisement‚ which is an environmentalist‚ is stating that trees are irreplaceable in our environment. They filter the air by capturing airborne pollutants‚ condensing heat‚ and absorbing contaminants such as carbon dioxide‚ nitrogen dioxide‚ and sulfur dioxide. Tress help regulate the ecosystem. When there are fewer trees‚ there are fewer chances for rain. As a result‚ there will be less water for providing irrigation for harvesting food. Once that occurs‚ there is famine‚ which

Introduction: The Eighth Grade of the Franklin School of Innovation studied the various parameters of Hominy Creek. These parameters were Nitrates (No3)‚ Dissolved Oxygen (DO)‚ pH‚ Phosphates (Po4)‚ Turbidity‚ Temperature (Temp) and the Flow Rate‚ contrasted to the weather for the day. Macroinvertebrates were collected and identified before being released. E. Coli tests were taken and analyzed during this period. Data was collected for 14 days‚ from March 22nd to April 19th. Tests were collected

studied. A significant diel flux change in nitrous oxide emission was observed. Dissolved nitrous oxide concentration averaged 0.149 nmole.cm-3 (SD = 0.09‚ n = 54) with a range from 0.096 to 0.574 nmole.cm-3. Dissolved and exchangeable inorganic nitrogen was present mostly in the form of ammonium (from 199 to 272 nmole.cm-3) with lesser amounts of nitrate (overall mean = 29.0 nmole.cm-3). Redox potentials in the sediments generally decreased with depth‚ with a mean value of 377 mV at the sediment

produces many commercially valuable compounds. The reaction itself involves the use of diazocarbonyl compounds which contain an N2 ligand on a carbon alpha to a carbonyl. The reaction is thermodynamically favourable as it involves the release of nitrogen gas. The carbon hydrogen bond is extremely strong and is difficult to break down; hence a catalyst‚ a substance which lowers the energy required for a reaction to occur‚ is required in order for the reaction to go to completion.
