Calcium carbonate

sample. Generally, to test the property change in the polymer by the influence of a filler/additive is done by processing several batches with different but gradual loading of the filler/additive. Here, we have to test the properties of nano Calcium Carbonate in the polymer matrix of polypropylene. For this, 12 batches are prepared by using the different size of filler by loading it at 5%, 10%, 15% and 20% by ratio in the polymer matrix. Ideally a 5kg of composite is compounded to test and…

The many aspects of power within a novel effectively shape how readers interpret the composer’s distinctive message. A close study of Weapon’s Training by Bruce Dawe, Mother Who Gave Me Life by Glen Hardwood and Brave New World by Aldous Huxley would enable readers to understand how effectively the writer has conveyed aspects of power. Knowledge is a form of power that can lead in many paths and at times, control those who desire it. Similarly, the power to dehumanise an individual can result in…

Until recently it was believed that the earth had only experienced 4 to 5 glacial periods, all of which occurred in the past 2 million years. (Louis Agassiz, 1837) However, globally conducted research has revealed that countless glacial advances have appeared over 200 million years ago, thus broadening our insight of the history of the earth system by 100 times. These astonishing advances have witnessed the introduction of a new sub-discipline—palaeoclimatology, which specialises in the study of…

Daguerreotype to Digital Introduction In the 21st century, photos have been the core of people 's emotions as it shows the best and the funniest moments of our life. The images that we capture in our everyday life are the images that we look back to and smile. The word photography comes from the Greek word "light" and "drawing".photography is a process which takes fixed images using the light on a chemical surface. (Dorling Kindersley. 2007). In this report, I will be exploring the…

The initial hypothesis that was made regarding the strength of the solid compounds was supported with this experiment. The hypothesis stated that potassium hydroxide would have the greatest effect on the acidic solution. This was supported here as it had the highest average change in pH by far. On average, the pH value of the acidic solution increased by 12.5. This is significantly higher than the increase of the other solutions, which only increased around a pH of 4. The reason why potassium…

Based on its performance, the high ranking draw solutes are calcium chloride (CaCl2), potassium hydrogen carbonate (KHCO3), magnesium chloride (MgCl2), and sodium hydrogen carbonate (NaHCO3), while based on cost replenishment, they can be ranked as KHCO3, magnesium sulfate (MgSO4), sodium chloride (NaCl), NaHCO3, and sodium sulfate (Na2SO4) [66]. Although, NaHCO3, KHCO3…

a)The five most important biogeochemical cycles are the oxygen cycle, nitrogen cycle, carbon cycle, sulphur cycle and the sedentary cycle. These five cycles can be classified into pools. Active pools are free flowing cycles controlled by life processes such as photosynthesis. Storage pools are segregated bodies controlled by physical processes such as, volcanic eruptions or earthquakes. Oxygen cycles through the environment in three major forms; gaseous atomic oxygen, and the…

quickly distributes to all organs and tissues. After about a month, our body eliminates it. The health hazard of the radiation causing cancer is about 0.004 percent. In 1.28 billion years, 89 percent of the time, half of the potassium 40 decays to calcium-40 by emitting a beta particle, while 11% of the time it decays to the gas, Argon-40, by electron capture. Besides radiometric dating, there are no specific commercial or medical uses associated with the radioactive properties of potassium-40.…

The objective for this report is to explain all the failures that might occur while making Pyrex and what are the cure that will help to prevent all of the causes and failures. Corning Inc. introduced Pyrex cookware in the market. Later, Pyrex was expanded to make clear and opal ware objects. Pyrex has a unique property that is Lower thermal expansion. Pyrex cookware is mostly made of borosilicate but it was later replaced by soda lime glass because that has a strong mechanical strength. Another…

What is acid rain? Acid rain is a form of deposition in which chemicals with an acidic pH level are taken out of the atmosphere through precipitation. When we pollute the air by burning fossil fuels, we create different chemicals that end up in our atmosphere. A few of these have chemical reactions with the water in clouds, and form (depending on the chemical) sulfurous and nitrous acids. When it rains, this acid is taken back to the ground. While pure water has a neutral pH level of 7,…
