  • Phosphates In Water Pollution

    1063 words, 5 pages

    Phosphates may be created by substituting some or all of the hydrogen of a phosphoric acid by metals. Depending on the number of hydrogen atoms that are replaced, the resulting compound is described as a primary, secondary or tertiary phosphate. Primary and secondary phosphates contain hydrogen and are acid salts. Secondary and tertiary phosphates, with the exception of those of sodium, potassium and ammonium are insoluble in water. Tertiary sodium phosphate is valuable as a detergent and water softener. The primary phosphates t

    Wide World of Fibers Abstract The whole aim of this experiment was to identify and analyzes fibers in a forensic laboratory, and to see their reactions in different conductions. The main purpose is to try to find what the unknown fiber was among different fibers. The fibers which were used in this lab were acetate, cotton, nylon 6.6, silk viscose and wool. Many of these fibers are from natural fibers. Natural fibers are from living things like the cotton plant, silk worm, goats, and sheep, these animals contribute in producing cotton, linen, and nylon 6.6 and silk. Many others fi

    Colour provides us with the ability to differentiate many things. The value of colour is so extensive. It ranges from the use of language to artists and designing. There are a variety of examples that require the existence of colour and without it, these things will just be boring. Television has moved from black and white to coloured. Without us realizing, black and white are also colours. They are just duller version of colours and are often not considered as colours. In my argument, I will be discussing about the various uses of colour in everyday life from the simplest objects to different

    Amino Acids

    1006 words, 5 pages

    Amino Acids Introduction: Amino acids are monomers of the macromolecule protein. Amino acids are composed of: a Carboxyl group (COOH), Amine group (NH2) and a variable “R” group all of which connect to a central carbon (which is also bonded to hydrogen). There are twenty standard amino acids. The variable “R” group dictates what the amino acid will be; hence changing the R group changes the amino acid and its chemical properties. Amino acids bond via peptide bond. Peptide bonds are formed from the dehydration synthesis of amino acids to form a covalent bond between the Carboxyl carbon

    The Origins of Life Before any inquiry can be made into biological evolution, the question of the origins of life must have an answer. For without first having an answer, evolution is deprived of its starting point. (Mader 2006) thus the origins of life have become one of the most significant questions in modern day biology, signifying an extensive hole in human’s knowledge of life and the development of life. Throughout history there have been many attempts in explaining the origins of life, it has now been segregated into 4 stages of chemical evolution and there are hypothesis on how each

    Carbon is known unto man as one of the greatest elements due to the vast varieties of its uses and responsibilities. It is known to be the sixth most abundant element in the entire universe. Here on Earth, carbon gives the framework of all the tissues of plants and animals. Everything that you would see on a normal day-to-day basis is built up on the roots of carbon. All proteins that are in the world such as hair, meat, and silk contain carbon. People even in the ancient times knew about carbon. So carbon is not just some new element that we ahs humans have just recently learned about.

    Photosynthesis uses light energy and carbon dioxide to make triose phospates (G3P). G3P is generally considered the prime end-product of photosynthesis. It can be used as an immediate food nutrient, or combined and rearranged to form disaccharide sugars, such as sucrose and fructose, which can be transported to other cells, or packaged for storage as insoluble polysaccharides such as starch. A commonly used but slightly simplified equation for photosynthesis is: 6 CO2(gas) + 12 H2O(liquid) + photons ? C6H12O6(aqueous) + 6 O2(gas) + 6 H2O(liquid) carbon dioxide +

The gel used was a mini-protean PGX precast gel 7.5% with tris/glycine buffers. The gel was packed inside a bag; it contained a comb, which was placed in the wells of the gel. The 7.5% gel means that the pores are larger than the 12% that some other students had. The 7.5% gel has 10 wells. It has numbered, marked well outlines on the cassette to ease the loading and the identification of the sample. It is an inexpensive buffer system, which means low running costs.

    Phenylketonuria is a rare congenital genetic disease in which a baby is born and lacks the ability to break down the certain amino acid phenylalanine. These few babies do not possess the gene that allows them to produce the enzyme called phenylalanine hydroxylase which is needed to break down the essential amino acid called phenylalanine. Phenylalanine is found in foods that contain protein, which most people do consume throughout their life, so this ability to process it would be extremely necessary, as it is hard to avoid a diet that contains some sort of protein.

The anhydrous form is a pale green/gray-white powder, whereas the pentahydrate (CuSO4•5H2O), the most commonly encountered salt and the salt that was used in this lab, is bright blue. A pentahydrate means that five water molecules attached copper (II) sulfate within a hydrate.

    Fire retarding properties PVC has inherently superior fire retarding properties due to its chlorine content, even in the absence of fire retardants. For example, the ignition temperature of PVC is as high as 455°C, and is a material with less risk for fire incidents since it is not ignited easily.Furthermore, the heat released in burning is considerably lower with PVC, when compared with those for PE and PP. PVC therefore contributes much less to spreading fire to nearby materials even while burning.Therefore, PVC is very suitable for safety reasons in products close to people’s daily lives.
