Decomposition

QUESTION Explain the significance and optimum value of the following parameter i. pH ii. DO iii. TDS iv. COD v. BOD ANSWER pH ph is the concentration of hydronium ion. It represents the ratio of hydronium ions (H3O + ) to Hydroxide ion (OH- ). It is numeric scale which decides the basic and alkalinity of water. If the ph of the solution is less than 7 than then the solution is said to alkaline and if the ph is greater then 7 then the solution is said to be basic. The ph of pure water at 25o C is…

Describe the importance of fungi to the forest ecosystem. Decomposition: Without microbes, organic matter on the forest floor and in the soil would never decompose. The rate at which these microorganisms decompose dead material is directly responsible for the availability of nutrients for plants. As the humidity and temperatures in rainforests are high, conditions are ideal for rapid microbial decomposition. However, the rates of decomposition will differ according to which microorganisms are…

Solution growth deposition This technique consists essentially of inserting the substrate into a solution containing hydrolysable metal compounds and pulling it out at a constant speed into an atmosphere containing water vapour. In this atmosphere, hydrolysis and condensation takes place. Finally the films are hardened by a high temperature cycle to form transparent metal oxides. Any hydrolysable compound including halides or nitrates but preferably metallo-organics are suitable…

atmosphere by plant respiration. Dead plant materials are decomposed by microorganisms to provide energy and, at the same time, CO2 is released back to the atmosphere by microbial respiration. This microbial respiration also takes place during the decomposition of soil organic matter (SOM), which is a mixture of live microbial biomass and organic residuals of dead plants and dead microbes. (Lou & Zhou 2006, 17-18). Therefore, through the ecosystem cycle, CO2 is produced by plant respiration…

Tony Kosgei Hour 5 Section #3 Hazardous Chamber Terrestrial Chamber To begin building our terrestrial chamber, was like a job for my group (which it wasn’t supposed to be) because my group were busy talking when I was busy building the terrestrial chamber (I was the terrestrial chamber captain). In order to build a terrestrial chamber you need fertilizer, grass seeds and most important of all is a consumer to main the gasses’ length. To begin with, on day 1 (8/26) we mixed stay…

sources and building off them, often quoting them wholesale as to remove any ideas about “fictional” vampires as opposed to the “folkloric” vampires found in the sources. He argues that the vampire of folklore are simply describing the natural decomposition process, but came to embody the fears the people of Eastern Europe had about death, calamity and disease. He shares the same status as Calmet, Summers, and Perkowski in that his work is sourced in almost all scholarship after him. There…

AC conductivity: Figure 4.19(a) shows the frequency dependent electrical conductivity of PCL5 electrolyte. The result shows that AC conductivity changes with temperature. The AC conductivity of the PEO/CoCl2 electrolyte increases with temperature is given in Table 4.4, which is the common characteristic of disordered materials. An increase in ac conductivity with frequency and temperature indicates charge transported by hopping through the defect sites along the polymer chain [70]. Also the…

Chemical reactions are a process that involves, rearranging the molecular structure of substances to create new ones. There are 3 types of chemical reactions, firstly there's synthesis, (e.g. 2Na + Cl2 → 2NaCl); then, the other type of reaction is decomposition (CaCO3 → CaO + CO2); and finally there is combustion. Combustion is a rapid chemical combination of a substance (fuel) with oxygen, including the production of heat and light (e.g. CH4 + 2O2 → CO2 + 2H2O). In these types of reactions,…

Introduction The seven soil formation factors have created unique soils throughout Saskatchewan. Through time soil processes such as additions, losses, translocation, and transformations have continued to form soils and make different horizons. Two catena's in Saskatchewan, one in the prairie and another in the boreal forest, were examined and classified into taxonomic group. The objective was to identify, compare, and contrast the major soil formation factors, morphological features, and…

Cooking food always involves a chemical reaction. It could be from baking a cake by mixing the ingredients and making a new substance to something as big as a nuclear explosion. There are five types of chemical reactions; they 're Synthesis, Decomposition, Single Replacement, Double Replacement, and Combustion. These are the main reactants in chemical reactions overall. Note that not all reactions fit in uniquely into only one category. Wilbraham, Stanley, Matta, Waterman 2015, “Every…
