Nitrous oxide

Since the water splitting reaction using semiconductor electrode reported by Fujishima et al. in 1972 [1], there is increasing interest in the development of metal oxide photocatalysts for environmentally friendly applications such as air purification [2], hydrogen production via water splitting [3] and the removal of organic molecules from water [4]. Recently, photocatalyst thin film has aroused growing interests instead of a powder type of photocatalyst. Photocatalyst film can be deposited…

Regarding these situations hypo sludge are used as a partial replacement of cement to increases the durability, setting time and strength of the concrete. In hypo sludge the chemical components present like Silicon Dioxide (SiO2), Calcium Oxide (CaO), Magnesium Oxide (MgO), etc...These are helps to increases the physical and chemical properties of concrete. Fig 3.2 Hypo Sludge Physical properties of Hypo Sludge Hypo sludge waste material is soft. From paper industries we get hypo sludge in wet…

Pyrite, also known as fool's gold, is similar in color and shape to gold, and is easily mistaken for gold because it generally occurs naturally with gold. Pyrite, though, can be easily distinguished from gold by running some simple tests and doing some simple observations. Pyrite can form in many areas and shapes, the larger crystals can be perfectly formed into intriguing cubes, penetrating twins, and many other fascinating forms, while the smaller crystals can give of a shimmering or…

where mCO2 is the mass fraction of CO2 in the solution, and MWsolution, MWbrine, and MWCO2 are the molecular weight of the solution, of the brine, and of CO2, respectively. Considering the definition of density as shown on 5.5, equation 5.3 can be modified to equation 5.6. ρ_CO2=MW_CO2/V_CO2 (5.5) "1" /"ρ" _" solution" =("1-" "m" _"CO2" )/"ρ" _" brine" "+" "m" _"CO2" /〖"ρ" _"CO2" 〗_" " (5.6) where ρ solution and ρ brine are density of solution and brine, MW CO2 and ρm CO2 is…

The removal of carbon dioxide in Recirculating Aquaculture Systems (RAS) has been an important topic of research due to the increasing amount of recirculating aquaculture systems being employed in the aquaculture industry. Carbon dioxide, as well as ammonia, are excreted by the fish and can be present in high quantities. Elevated levels of CO2 accumulation within the recirculating water could have toxic effects on fish. The maximum level of CO2 and ammonia that can be present in the tanks…

In Webster’s dictionary the definition of Environmental Science states that, it is “the branch of science concerned with the physical, chemical, and biological conditions of the environment and their effect of organisms”. In the experiment Environmental Science deals with how the human body will be affected in the environment with or without using electrolytes during an exercise. While conducting the experiment Aleckzar used his brother Alekczar to see if there would be a significant difference…

reaction that forms the compound, magnesium oxide. This reaction occurs due to the heat that provides energy to activate the reaction. A blinding white flame will burn as the reaction occurs. In this lab, magnesium is burned in an open crucible over a Bunsen burner several times until the magnesium ceases to burn. This process allows for the magnesium to completely react with the oxygen found in the open air, forming the chemical compound magnesium oxide. However, our lab did not provide us with…

1. Introduction Pre-industrial revolution, humans beings used to live a primitive life whereby they used wood for cooking, warming house; as biofuel. Even later when they lived in houses, they used candles to light up their homes. Post-industrial revolution, human beings discovered new energy resources which have made life much easier to live. And the discovery of these resources (coal and oil), have also supported the advancement of new technologies e.g. automobiles, airplanes, generation of…

Nitrogen and phosphorus are the major limiting nutrient elements in a variety of aquatic ecosystems and are altered by anthropogenic activities; such as row crops, feed lots, and humans (Elser et al. 2007). Larger inputs of nitrogen cause an abundance of phytoplankton and macrophyte production (Ferree and Shannon 2001).The purpose of this study was to examine nitrogen and phosphorus levels at Ada Hayden Lake in the comparative context of their effect on phytoplankton abundance as well as…

substance. This can be seen in reaction #2. In reaction #2, magnesium reacts with oxygen to produce magnesium oxide. Although the students can only see magnesium and magnesium oxide, the students were informed on the lab sheet that oxygen was also one of the reactants. This reaction allowed students to see how two substances, magnesium and oxygen, react to produce one product, magnesium oxide. Students were also able to see evidence of chemical reaction taking place. In reaction #2, when…
