2. If two different compounds have the same Rr value, how might they be identified using paper chromatography? 3. Why is it important to keep the spots on the paper as small as possible? 4. If the solvent pool at the bottom of the beaker touched the spots on the 1.5cm line, what would happen to the spots? How would you address this error? 5. If you were teaching a student how to do paper chromatography, what three pieces of...

Chromatography: Separating Mixtures Introduction: Magic marker inks are often mixtures of several compounds. Paper chromatography is a common method of separating various components of a mixture. After separation, you can observe the different colors that make up a particular color of magic marker ink. You can also calculate a ratio Rf, which compares how far each compound traveled to how far each solvent (substance that dissolves another substance) traveled during the experiment. Rf = Ds/Df Ds = Distance traveled by...
Part B (20 marks) Figure 2 shows a three phase 22kV, 50Hz radial system, which is to be protected by two inverse- time over-current relays B1 and B2. The maximum loads for this system are L 6 MVA, and L2- 5 MVA. The maximum fault currents at bus 1 and bus 2 are 1500A and 1000A respectively. The minimum fault currents at bus 1 and bus 2 are 900A and 650A respectively The line currents are measured using current transformers...

when will temerature changes occur in the first part of the experiment? EXPERIMENT 4: POSTLAB EXERCISE Name Assume vou have a mixture of two types of plastic and need to separate them You know that plastic A and B are both white in color, plastic A will dissolve in toluene and plastic B will not; plastic A has a density of 0.57 g/cm' and plastic B has a density of 1.08 g/em Oh, by the way, your boss, wants all...
