Explain how turbulence enhances convection heat transfer 4. Describe the significance of the Reynold's number, Nusselt number, and the Prandtl number 5. List common situations where external convection occurs 6. Explain the importance of the film temperature and use it to specify thermophysical properties of a fluid 7. Explain the significance of boundary layer...
1. Flammable substances will burn more rapidly in pure oxygen than in air. Explain why this happens 2. in terms of energy and bonds, explain what causes a reaction to be exothermic or endothermic. Do not simply tell what it means for a reaction to be exothermic or endothermic.
Explain in detail why does bromination of ethoxy benzene occur more rapidly than phenyl benzoate? Please illustrate also.
3. Explain why, in a chemical reaction, the concentration of a reactant decreases more rapidly at a lower time t than at a higher t.
Explain why the most polar compound layer stays in the organic layer, while the less polar compounds go into the aqueous phase. (This is for a liquid-liquid extraction) The most polar compund is caffeine and the solvent is ethyl acetate. I know it has to do with the caffeine not being able to deprotonate but I’m still confused and would like more information on why is can’t deprotonate.
Provide a resonance structures which explain why ortho and para nitrophenol are much more acidic than phenol
Clearly explain why health outcome is so much more than a combination of health care, individual behaviors, and/or genetics?
Why potassium permanganate and methylene blue dyes diffuse more rapidly through water than agar gel?
Explain why, in a market with negative externality, too much output (more than the efficient amount) is produced and sold and positive externality, too little output (less than the efficient amount) is produced and sold. If you use a diagram in your answer, make that diagram large and label all axes, curves, and points.
