Discussion of Results and Scientific Explanation To achieve the goal of determining an unknown acid or base, anion and cation test were performed. These tests allowed for the components of the solutions to be identified, therefore, achieve the second goal. The pH was also used in to help find the identity of the unknown solutions and it was used to draw conclusions about the solutions. Dilutions were used to help understand the different behaviors of different concentrations. Household items…

[2] They contain many hazardous, if not radioactive, materials such as: Mercury (found in batteries), lead, chromium, barium, and other heavy metals (found in cathode ray tubes in TVs and monitors) which cause renal toxicity and in some cases mental retardation. On the other hand, cell phones contain large amounts of gold and silver; it is estimated that America ditches about $60 million worth of gold in silver…

1. Introduction Fossil fuels are used to satisfy a very significant fraction of the world energy demands. The use of fossil fuels comes with some adverse effects, prominent among which is the emission of CO2. Carbon dioxide significantly contributes to global warming and, consequently, causes climate change. This has called for international policies like the Kyoto protocol and Copenhagen summit that set limit on greenhouse gases (GHG) emission [1]. Renewable energy sources are carbon neutral…

Multimedia Definition: Multimedia is a file format in computer include a lot of forms like sound, videos, images, graphics, and text that we use in our daily life.

History of Communication The communication methods employed by human dates back from a very early stages of civilization. In the primitive ages, communication were based on human voice. But it had a limitation, the distance. As distance grew between two people, messages got hard to convey due to the limitation of vocal cord. Next big step taken by human civilization was the invention of fire. He soon realized that this fire could be used for communication. During the attack in China, soldiers…

James Apostolico November 6, 2014 The Chemistry of Natural Waters Chemistry 111 Section: 005 Kareem Ali, Dima Alfawaz Stephanie Le Clair Introduction Water hardness is a way of defining the quality of water based upon the amount of Ca2+ and Mg2+ions that the sample contains.1 Water mostly becomes hard by flowing over weathering rocks which release these ions into the water. These released ions dissolve in water and then react with various elements, ions and compounds that…
