2.6.6. Levels of total ammonia nitrogen‚ nitrite‚ nitrate and phosphate in the water samples The mean TAN levels in the present study in all the sampling stations were below the recommended level of 0.1 to 1.0 mg/L prescribed by Boyd (1990). However‚ when the level recommended (< 0.2 mg/L) by Chavez (2009) is taken as a standard‚ it was found to that 35% of the study period‚ TAN levels were above the acceptable limit in the feeder canal and the pond 3. Ferreira et al. (2011) has recommended 0

an acid formed from reaction of ammonia and oxygen. Nitric acid is a colourless acid when it’s pure‚ or can be found yellow or red. This acid can be very corrosive to eyes and skin and can cause severe burns to human skin and tissues. It is miscible to water‚ and has a very pungent smell. Nitric acid is very reactive and can is able to melt many metals‚ and non metals. As a solution‚ nitric acid is known as a good conductor of electricity. When combining ammonia and oxygen‚ water and nitrogen‚

surroundings. It also releases gases. An exothermic reaction is a reaction that releases energy as heat. Since the energy is released‚ the exothermic reactions feel hot. Methods/Materials I did three experiments. I mixed lemon juice and baking soda‚ammonia and vinegar‚ and finally‚ hydrochloric acid and sodium hydroxide. I did each experiment when the acid was 0‚ 20‚ 40‚ 60‚ and 80;all in degrees Celsius. Therefore‚ I could compare the exothermic reaction with the endothermic reaction at each temperature

relatively constant pH in blood. Cells of the transport epithelium secrete hydrogen ion into the lumen of the tubule but also synthesize and secrete ammonia. Ammonia is a buffer that trap hydrogen ion in the form of ammonium ions. The more ammonia secrete‚ the more acidic the filtrate and the blood will be less acidic. That is why mostly urine contains ammonia. The proximal tubule also reabsorb the buffer of bicarbonate from filtrate due to pH balance in blood. The filtrate will continue to descending

constant (L) and is equal to 6.02 x 1023. 1 mole of carbon-12 contains 6.02 x 1023 atoms. Therefore‚ 1 mole of any substance contains 6.02 x 1023 atoms/molecules/ions. For example‚ 1 mole of aluminium contains 6.02 x 1023 Al atoms 1 mole of ammonia contains 6.02 x 1023 NH3 molecules 1 mole of iron ions contains 6.02 x 1023 Fe ions Atoms Calculate the number of atoms in 2 moles of silicon.

Samples of salt complexes of cobalt‚ zinc‚ copper and manganese were prepared in agar medium forming a gel and then were left to react with ammonia (ligand) for a period of four days and the data was recorded. After analyzing the data in Logger Pro Software and plotting the graph of the dependent variables and the change observed‚ it was concluded that the crystal growth is affected by magnetic

the nitrogen‚ the amino group has to be removed (deamination)‚ to form ammonia and a keto acid. The keto acid can be used in respiration‚ or converted to lipids or cholesterol and stored. Fish can directly excrete ammonia. Ammonia is highly toxic and soluble in water‚ it takes a lot of water to flush out ammonia‚ but as fish have a plentiful supply‚ they can simply diffuse the ammonia out through cells. Birds convert ammonia into uric acid. They do this as they cannot carry as much water as humans
