of an Organic Solid A. What needs to be done: In this lab‚ one will identify the identity of a colorless organic solid by experimentally finding the physical properties of the solid. Such properties include melting point‚ mixed melting point‚ and IR spectrum. With these properties‚ one will be able to compare their results of the organic solid to see if any other classmates have the same unknown sample. B. Timeline: Step one: Obtain a sample of the unknown colorless organic solid. (make sure

Before this fieldtrip to Lee County Solid Waste Facility‚ I lacked knowledge regarding the fate of our trash. My idea of a waste facility went along the lines of a big dump site or landfill; contrarily‚ I am familiar with what items are deemed recyclable in Lee County. My experience at the Lee County Solid Waste Facility‚ operated by Covanta‚ showed me how garbage has the potential to provide electrical power to over 250‚000 homes. Waste to Energy is a primary example of how America can become more
