Although I love science‚ I encountered more problems in this subject than any other. Recently‚ I was assigned a lab. The purpose was to let Copper Sulfate react with Aluminum and obtain Copper. Before the experiment‚ I set up the stoichiometric equation carefully‚ predicting the production of Copper using my assigned mass of Copper Sulfate. Additionally‚ I intentionally made Copper Sulfate an excess in my equation‚ since it would be dissolved in water and I would only have to collect Copper at the

Discuss in detail the Cell Cycle‚ Mitosis and Meiosis. Cells have the ability to grow‚ have particular functions‚ and replicate during their life. Although cell enlargement is part of organismal growth‚ cell replication is also required and allows growth without each cell becoming too large. All of these activities are part of a repeating set of events known as the cell cycle. The major feature in the cell cycle is cellular replication and what enables for cellular replication is the process

Objective: The purpose of the lab is to learn filtering techniques. Specifically‚ to form and filter a calcium carbonate precipitate using a Buchner funnel. Procedure: a.) Prepared a mixture of .5 M calcium nitrate (45 mL) and .01 M sodium carbonate by combining and stirring the two liquids in a beaker. Allow the mixture to stand. b.) Prepare the filtration assembly. The assembly consists of a tapered flask with a buchner funnel inserted in the top. The funnel has a rubber stopper attached

Camille Ray Prof. Huggins ENGL 1120 February 24th‚ 2015 Evaluation of the product Essiac as a cure for cancer(s) Doctors continue to study all types of cancers‚ so they can find a cure. More and more people are diagnosed with cancer each year. In 1995‚ “an estimated 450‚000 people in the United States were diagnosed‚ of which 10% to 15% were already locoregionally advanced” (Ames et al‚ 1996). Cancer has been affecting people for centuries‚ where it was “treated with such methods as amputation or
