Experiment 3: The preparation of acetaminophen (paracetamol) with thin layer chromatography (TLC) to monitor the reaction. Abstract: This experiment is to demonstrate the preparation of paracetamol and its properties. Reflux and filtration of 4-aminophenol and acetic anhydride formed the crude sample. Further analysis of dry white crystals were used to give quantitative measurements and a percentage yield of 46% was obtained. The overall conclusion is that the acetic anhydride reacted with the

Crust is the first and upper most layer of the Earth. There is Continental Crust which sits on top of Oceanic Crust. This layer is made frequently from granite rocks and is solid. Continental Crust is approximately 32km. Below the Continental Crust is Oceanic Crust. It is about 8km. This part of the Crust is made from basalt rocks. The Crust is most of lithosphere and is the coolest layer by far. Mantle is like silly putty consistency. It is the largest layer of Earth sitting under the Crust.

instantly made me realize what concept I was observing. The concept I began to observe was the social penetration theory. This means that the self has many layers and people learn more and more layers of a person based on the breadth and depth they are allowing to go with you. Breadth is the different perspective one may reveal in each layer and depth is to what extent they reveal something and how informative it is about the subject. This idea was able to relate to this situation because they seemed

There are many different layers within the Earth. The core is at center of the Earth. The Earth’s core takes up sixteen percent of Earth’s volume‚ containing thirty-three percent of its Mass ..Pressure rises steadily inside the earth because of the weight of overlying rock. Therefore ‚the Pressure at the outer boundary of the core reaches 1.37 million atmospheres‚ 3.7 million Atmospheres. The core is made mostly of iron and nickel and possibly smaller amounts of lighter elements including sulfur
