Introduction Acid rain is a rain that contains a high concentration of pollutants, chiefly sulfur dioxide and nitrogen oxide, released into the atmosphere by the burning of fossil fuels such as coal or oil .It can have harmful effects on plants, aquatic animals and infrastructure, when the sulfur dioxide and nitrogen oxide, react with the water . The chemicals in acid rain can cause paint to peel, corrosion of steel structures such as bridges, and weathering of stone buildings and statues.…

To a small extent calcium carbonate is also formed when calcium silicate and aluminates of the hydrated cement react with carbon dioxide from the atmosphere. Carbonation process in concrete results in two deleterious effects (I) shrinkage may occur (ii) concrete immediately adjacent…

Ocean Acidification, a process where the pH of ocean decreases as Carbon Dioxide (CO2) concentration increases in the water from the atmosphere. Since industrial revolution, the concentration of CO2 has dramatically increased in our atmosphere due to the burnings of fossil fuels, deforestations, and many more actions that humans take to make our lives luxurious. About 30% of CO2 from the atmosphere is absorbed by the oceans, making marine life’s survival uncertain. It has huge impact in the…

Although wastewaters contain elements which are vital for the Spirulina growth, as it contain other unknown substances as well, its influence on the rate of growth of the Spirulina's cannot be unambiguously hypothesized. Since bicarbonate and sodium carbonate were not added to the effluent water but only to the portable water, it is assumed that the higher concentration of the…

The experiment that I will be conducting focuses on how fast one tablet of Alka seltzer can dissolve in various temperatures of water. The core of this procedure is to determine the impact that temperature has on how fast something dissolves. My hypothesis for this experiment would be that the Alka Seltzer that dissolves the fastest would be the one that was placed in the water with the highest temperature. There will be controlled and manipulated variables explained throughout the experiment.…

Thermoregulation is the process of regulating the internal body temperature of animals within a certain range. Endotherms, such as mammals and birds, thermoregulate internally by generating heat from metabolic processes and are able to keep their body temperature high and relatively constant, adapting to the environment to maintain homeostasis. This type of thermoregulation requires a high metabolic rate, that enables organisms to be more physically active without having to rely on the…

Ashley-Ann Burnett October 4, 2015 Lab #3: Acids, Bases & pH SLS43-14/7-8 Pre-Lab Questions: 1) An isotope is an atom with a different atomic weight due to changes in the number of neutrons in the nucleus. Some examples of isotopes are Protium, Deuterium, and Tritium, which are all Hydrogen atoms. Instead of the zero neutrons Hydrogen has in its Protium form, Deuterium and Tritium have two and three neutrons respectively. This change in neutron number and…

The marine environment at Lorde Howe Island was a significant factor for World Heritage Listing in 1982. The island has a combination of temperate and tropical marine species, including coral reef in the near intact condition of the Island waters. During winter, ocean currents at 17 degrees’ surround Lord Howe Island and larvae of many organisms from cool southern parts of Australia are transported to the Island. During summer, the warm East Australian Current sweeps down from the Great Barrier…

Results/Discussion: 2-butanol and Acetic Acid were refluxed together with anti-bumping granules and a catalyst of sulphuric acid for 1 hour and five minutes. Anti-bumping granules are small ceramic granules which have rough edges. They are added within a mixture to encourage smooth boiling. In this experiment by adding the anti-bumping granules we were able to achieve smooth boiling throughout both the reflux process and the distillation process. Without adding these granules, bubbles of vapour…

utilize this compound are, laboratory work, manufacturing, biology research, medical history, photography, and even the art of ceramics. Silver nitrate has been known by scientists worldwide to be very helpful in detecting the presence of Chlorine, Carbonate, Hydroxide, Sulfide, Phosphate, Bromine and Iodine ions. Chlorine will create a white colour after being exposed to silver nitrate. Bromine will create a pale yellow colour, and Iodine will produce a solid yellow colour. Silver Nitrate is…
