1. What might happen if a student used a pen to mark the baseline on the chromatography paper? The solution will m ove to the top and you would not be able to calculate the Rf value that is com pared to the distance that a com ponent traveled in the stationary phase reached by the solvent. 2. What would happen if the student did not stop the development before the solvent reached the top of the paper? The solvent would wash away the dye. 3. What would happen if the solvent level was abov...

Amino Acids Found in Proteins • Amino acids contain two functional groups, an amino group (-NH2) and a carboxyl group (-COOH) which are formed on a carboxylic acid. o Alpha amino acids are those where both functional groups are attached to the same carbon. o Side chain/R group and hydrogen atom are also attached to alpha carbon.  Side chain determines the properties of amino acids and its functions. Terminology • There are a variety of different types of amino acids, however the MCA...

Unit 14: Assignment 1 - Applications of Organic Chemistry REVISION QUESTIONS WHICH WILL HELP YOU LERAN MORE AND GET TO UNDERSTAND THE TOPIC WELL AS YOU PREPARE FOR YOUR FINAL EXAMS.

MODULE 1 EXAM Question 1 Click this link to access the Periodic Table. This may be helpful throughout the exam. 1. Convert 845.3 to exponential form and explain your answer. 2. Convert 3.21 x 10-5 to ordinary form and explain your answer. 1. Convert 845.3 = larger than 1 = positive exponent, move decimal 2 places = 8.453 x 102 2. Convert 3.21 x 10-5 = negative exponent = smaller than 1, move decimal 5 places = 0. Question 2 Click this link to access the Periodic Table. This ma...
