Of the volcanoes that are located in the United States there are two which are world renowned for their activity and their power to change the region surrounding them. The two volcanoes would be Mount Saint Helens and Mount Kilauea. In order to get a better understanding of these volcanoes we will be comparing and…

The chemical evolution theory, proposed by A.I. Oparin in 1923 and later supported by J.B.S. Haldane in 1928, explains the origins of life on Earth. According to this theory, the early Earth was very different from how it is today. To effectively understand this theory, we can explore it through the following categories: Biogeny Chemogeny…

Introduction The purpose of this lab is to create two material samples through the process of powder metallurgy. After these samples have been manufactured completely through this process then they are evaluated under a microscope. One sample was sintered, and the other one was in its original compacted state for a comparison of how sintering…

Determination of the Waters of Crystallisation/ Water of Hydration, In Hydrated copper (II) Sulphate Introduction In nature there are some salts that will have water in their crystalline structure. These salts are commonly known as hydrated salts. Hydrated Copper (II) sulphate is one of these, as suggested by the use of the word hydrated in…

The top five manufacturers and users of ethyl alcohol in 2005 were Brazil bring forthing 4.35 billion gallons per twelvemonth, The United States bring forthing 4.3 one million millions gallons per twelvemonth, China bring forthing 530 million gallons per twelvemonth, The European Union bring forthing 250 1000000s gallons per twelvemonth and India bring forthing 80…

Objective: Separate and purify acetanilide from a mixture by recrystallization. Compare the melting points of crude and recrystallized acetanilide. Introduction : The most common method of purifying solid organic compounds is by recrystallization. In this technique, an impure solid compound is dissolved in a solvent and then allowed to slowly crystallize out as the solution…

My hypothesis is that dissolved Phosphate will change for the total phosphorus when left under a light. I believe that suspended phosphorus has the biggest impact on the eutrophication of lakes. When there is an increase of phosphorus in lakes, this leads to and increase in phytoplankton. This then leads to a decrease in water…

The carbon cycle is the biogeochemical cycle by which carbon is exchanged among the biosphere, pedosphere, geosphere, hydrosphere, and atmosphere of the Earth. Along with the nitrogen cycle and the water cycle, the carbon cycle comprises a sequence of events that are key to making the Earth capable of sustaining life; it describes the movement of carbon as it is recycled and reused throughout the biosphere. The global carbon…

Cloud Formation Cloud A cloud is a visible mass of condensation droplets. Water moves into the atmosphere through the process of evaporation and transpiration. Water vapors join the dust particles in the atmosphere to form clouds.  Finally, water returns to Earth as precipitation in the form of rain, snow, and hail. Clouds cannot be formed…
