Organic Chemistry Laboratory Work
Preparation of Acetylsalicylic Acid (ASPIRIN)
We used Sulfuric Acid for Quesiton 1.

Esterification reactions are commonly used in the chemistry world. What are esters? Using generic organic acid R-COOH and generic alcohol R'-OH, provide a quick sketch of what happens during an esterification reaction. Provide a reference for your source. 1. State Dalton's Law of Partial Pressures. 2. Use your text or other reference to find the partial pressure of water at 25, 26, and 27°C and record those values. 3. A gas sample was collected over water at 25°C. The total...

#1. To reduce nitrogen oxide emissions from a diesel engine, one commonly used strategy is exhaust gas recirculation (EGR). In a stack-type EGR cooler, exhaust gases flow through tubes with a rectangular cross-section (4 mm x 6 mm). In each tube, the mass flow rate of exhaust gases is 0.0001 kg/s; the gases enter at 140°C while the inner surface of each tube is maintained at 80°C due to water being circulated as a coolant. The length of the tube...
