Week 2 Lab |Step 1: First Year Costs | | Question 1: What would the first-year costs be to AML if it purchased the 10 used 20-foot containers? How long would it take to recoup the investment‚ assuming that the mushroom traffic continued? Based on 120 container shipments per year with 10% loads return or 12 containers‚ this would generate revenues equal to the associated cost.

elimination reaction on 2-methylalcohol with an acid to produce alkenes as a product. The product formed is separated through distillation. Because more than one alkene product can result from the reaction‚ Gas Chromatography is used to analyze the composition of the product mixture. IR spectrometry is also carried out to confirm the product. Procedure This experiment was carried out as described in Class Pak. The heat source power was set to 3 for fractional distillation and to 2 for simple distillation
