Explain what happens during the separation process when two molecules pass through a column or up a TLC plate.
In detail, explain what happens to water when it is continuously flowed through a packed column. Please talk about what is going on with the water at a molecular scale. You can use diagrams and equations to make it as easy to understand.
Describe what happens to when Snicker bars and Twizzlers, both physically and chemically, once they pass through your lips. In other words, trace the main ingredients (from a complex food source completely through molecular and submolecular levels) from the moment you start eating them until they are completely broken down into building blocks and cellular energy. Focus your answer on what happens to the key molecules in the food, and on the cellular aspect of these conversions. Also, describe how...
1. Explain how a fractionating column increases the separation of two liquids. 2. What is an azeotrope? Do you think the mixture used in the lab is an example of an azeotrope? Explain. 3. Explain how the boiling point of a liquid is affected by the addition of a non-volatile solute (hint: it is a colligative property). Is the temperature above such solution lower, higher or the same as the pure liquid? Explain why. 4. You were asked to record...

When you move a rope up and down, waves are created. If the waves pass through a slot, they will be affected differently, depending on the orientation of the slot. Using the rope waves and the slot as a model, explain how polarizing glasses affect light waves.' a. If the wave (electric field) is vertical and slit (polarizing molecules in the glass is horizontal), the wave will pass. b. If the wave is vertical and slit is vertical, the wave...
When a molecule of ethylenediamine (en) replaces two molecules of NH3 in Co(NH3)63+, what happens to the entropy of the system? A. It increases. B. It remains the same. C. It decreases.
(3) During the separation of two steroids by HPLC on a C18 column, a student reported the following elution times with a certain % acetonitrile/water mobile phase (uracil was added to the steroid mixture) tm (uracil) 1.2 min t, (steroid1) 4.55 min t, (steroid2) 6.55 min base width, w (steroid 1) 0.56 min base width, w (steroid 2) 0.79 min a. Sketch the chromatogram to illustrate the above separation. Label the peaks and the x- and y-axis. Calculate the resolution...

Explain why people who are adrift in a lifeboat without a supply of fresh water are advised not to drink ocean water. note - Ocean water is saltier than body fluids like blood plasma. 4. In terms of osmosis, what happens when fresh water is inhaled into a person's lungs? (Lung tissue is a semipermeable membrane.)
