Freshwater Treatment for Amoebic Gill Disease Freshwater treatment for AGD requires checking for few things before and during the treatment to carry out a successful and effective treatment. 1. Freshwater Source: The freshwater source should be checked for temperature, total ammonia nitrogen and ammonia percentage, pH, hardness, salinity and any harmful plankton. Temperature: Freshwater with temperature closer to the temperature that treating fish are being reared in is best choice. Colder…

In this study, multiwalled carbon nanotubes@poly(p-phenylenediamine)-prussian blue (MWCNTs@PpPD-PB) nanocomposites were synthesized and used for the nonenzymatic electrochemical detection of hydrogen peroxide (H2O2). The PpPD layer also helps the MWCNTs to be dispersed in the water together with the PB formation and fixing on the surface of the MWCNTs. Moreover, PpPD, a conductive polymer, increases the electronic conductivity and stability of MWCNTs. By combining the selectivity and catalytic…

human error when the solid contents when transferred to the filter paper because perhaps not all of the contents were completely transferred. In addition, the measurements of how much liquid was poured into the beaker may be off. Post Lab Questions 1. The moles of CaCO3 is 0.01828 because the mass of CaCO3 is 1.830 grams, therefore in order to get the moles of CaCO3, we must divide 1.830 by the molar mass of CaCO3, which is 100.1. This yields 0.01828 moles. 2. Dividing the mass of the unknown…

2.8.4 Properties The application of carrageenan as food additive depends on its performance such as forming thick solution or gels. For example, κ− carrageenan forms strong and rigid gels with potassium salts, forms brittle gels with calcium salts, clears gel with sugar addition, and exhibits syneresis. On the other hand, ι− carrageenan forms elastic gels with calcium salts, clears gel with no syneresis, and creates a gel that is freeze/thaw stable, while λ− carrageenan is not gel-forming but…

cells There are 3 main types of commercially available cells: 3.1.1Mono crystalline Silicon PV& Polycrystalline Silicon PV The occupational health issues are associated to chemical burns and inhalation of fumes from hydro fluoric acid (HF) and other solutions of acids (e.g., HNO3) and alkalis (e.g., NaOH) used for cleaning wafers ,removing complete oxide layer, and cleaning the reactor. Performing the slicing of wafers also results in solid waste for example (e.g., small pieces of…

because the final velocity is slower than the initial velocity. In figure two all deceleration curves are acceptable because the range of r2 is 0.89-0.99 representing a good fit; therefore, there is no possible errors to explain. In comparison to figure 1, beetroots that were pretreated with low concentration of salts had a faster diffusion rate than beetroots that were pretreated with a high concentration had a slower diffusion rate. In the time interval of 3-9 minutes, the sodium chloride…

Pale yellow precipitate appears the fastest, following with pale cream precipitate and white precipitate takes the longest time to appear. This shows that 1-iodobutane is most reactive whereas 1-chlorobutane is least reactive. The order of reactivity reflects the strengths of the carbon-halogen bonds. The carbon-iodine bond is the weakest and the carbon-chlorine the strongest of the three bonds. In order for a halide ion to…

buffer solutions to sustain the structure and activity of biological components such as DNA, RNA, proteins, carbohydrates, and lipids. Buffer solutions are remarkably resistant to pH changes and generally consist of a weak acid and its conjugate base or a weak base and its conjugate acid. In the laboratory, artificially made buffers are often used to help maintain a biological system at the proper pH. A laboratory buffer should be inert in the system being studied. For example, Tris buffer is…

seawater that was collected all around Galveston Bay and allowed an understanding of the composition of saltwater. The students were separated into four groups, each received a sample of seawater from a different location, such as Buoy 21, Day Mark 1, Pelican Island Cut, and the Coast Guard Station. The main ingredient in saltwater is water. Water is composed of two hydrogen atoms and one oxygen atom that are covalently bonded and forms a polar molecule because the electrons are shared…

For much of human history, salt has been mined from the areas around dry lake beds and in deposits left after ancient seas dried up. These bodies of water all evaporated, leaving their crystallized salt deposits behind. Mined salt is sourced from these deposits. It differs from sea salt in that sea salt is taken from living oceans. While it is usually ground finely for sprinkling onto food as table salt, some of it is kept in a coarse and chunky form that is referred to as rock salt. Rock salt…
