Chemistry Honors Mrs. Moreno Period 5 INTERPRETING THE PERIODIC TABLE Partner’s name: Faranak Hajikhan, Pablo Moncada, Albina Contreras and Karla Santos Title: Interpreting the Periodic Table Date: 12-18-14 Subject: Honors Chemistry / Period 5 Introduction: The periodic table is a table of the chemical elements in which the elements are arranged by order of a atomic number. The periodic table also has a special name for its vertical columns. Each…

Environment is the totality of all social, biological and physical factors individually as well as collectively that compose the nature and man-made surroundings. Man is a part of environmental system. The environment consists of four components atmosphere, hydrosphere, lithosphere and biosphere. The temperature variation in these components is the basis of heat budget of the earth. While the elements (Carbon, Nitrogen, Phosphorus, Oxygen etc.) and compounds that sustain us cycle endlessly…

The solubility of Barium Sulfate can be also determined by the solubility rules whereby most sulfates are soluble in aqueous solutions except for Calcium Sulfate and Silver Sulfate, which are slightly soluble and Barium Sulfate, Mercury(II) Sulfate and Lead(II) Sulfate are insoluble. The weight of the precipitate measured was 0.1602g. However, when compared with other groups, our group’s yield was…

intact for the species living in the water. When oceans absorb high levels of carbon dioxide, the acidity levels raise and the natural order of the ocean becomes compromised. This is what is known as “ocean acidification” or “OA” for short. Calcium carbonate minerals are building blocks for skeletons and shells of marine organisms.” This causes oceans more dangerous for people to swim at because of the high level of carbon dioxide, as erosion continues it would be more problematic to deal with…

What results would lead you to the conclusion that the material tested has high potential for AMD generation and would indicate that more extensive and intensive tests should be done to confirm the results. When looking at the Paste pH and Electrical Conductivity Tests, we are looking for an acidic environment and an environment with a high concentration of salt. Specifically, if our site sample has a pH of less than 4, then that indicates that the sample is acidic. If our site sample has an…

A.2. Procedures for proper storage of the classroom chemicals General Requirements for Classroom Chemical Storage Store all chemicals inside a locked cabinet with sturdy shelves. Label cabinet with warning label and contents. Secure cabinets and shelving to the wall or floor. Segregate chemical storage away from students in a ventilated, locked storeroom. Chemical Segregation Store acids in a labeled, locked, corrosion resistant cabinet. 1 M hydrochloric acid, HCl acid; storage code: White.…

1. Growth challenges In this chapter, a growth challenges in front of the giant Coca Cola Company would be analyzed as well as their influence on growth processes in the company. The product development in terms of growth would be examined as well. For the purpose of examined issues, it is worth mentioning that Coca Cola was created and developed in response to health issues and concerns. At the very beginning in 1886 a pharmacist, called John Pemberton removed the alcohol from his product…

Biogeochemical cycles are the way in which nutrients move through the earths system. It is a pathway for chemical elements to move through biotic and abiotic factors. The ocean contributes largely to these cycles as it acts as a reservoir or sink for the accumulation of nutrients. Even water itself is recycled through precipitation, evaporation and condensation. This is a typical cycle that can be observed for the vital elements of life such as carbon and nitrogen. Microbes are essential to the…

burrowing worms. Coral reefs are another ecosystem effected by tides and currents within the ocean. They often form in warm, shallow sea waters and rise to or near the surface. Formed from mounds or ridges of living coral, coral skeletons, and calcium carbonate deposits from other organisms such as calcareous algae, mollusks, and protozoa, coral reefs have often been referred to as rainforests of the sea. Coral needs specific, favorable tides to grow and does not typically form where the tide…

Although most of substances dissolve more easily in warm water, some dissolve more easily in cooler water. Unfortunately, some of these substances, such as sulfates and carbonates, are found in seawater. Calcium sulfate (CaSO4) is one of the most important, which begins to leave solution when seawater reaches about 115 °C (203 °F). This material forms a hard scale which coats any surfaces or tubes present. Scale creates mechanical and thermal…
