Describe how red blood cells are produced and based on their structure, how they transport gases in the blood. Explain how oxygen and carbon dioxide are transported in the blood. How does the means of transport relate to then solubility and chemical reac...
Describe in detail what you know about the enthalpy, entropy, and free energy changes when a sample of gas condenses to a liquid. How does temperature affect these changes? The entropy of formation of Mg2+ (aq) is -138.1 J/mol K. Explain why from a molecular...
What would you expect for the changes in enthalpy, entropy, and free energy when a sample of liquid evaporates. How does temperature affect these changes? Explain the relationship between entropy and the number of microstates. How do you predict the sign of the entrop...
How does the body carry cholesterol in circulation in the bloodstream? In a few words, describe how a junction potential arises at a membrane/solution How can one demonstrate that a reaction is diffusion controlled, verses one that is simply very rapid? Give a brief example to your explana...
How do intermolecular interactions affect the glass transition temperature? Why is heat absorbed in glass transition? Why are tetrahedral complexes always high spin? Why are intermolecular interactions minimized when temperature goes up or when molecule speed increases? Why are metamorphic rocks that are...
Solubility of slats : Solubility is the capability of a certain amount of solute to dissolve in 100ml of water at a specific temperature. It also gives concepts on the separation of salt mixtures in relation to their solubilities. Answer and Explanation:1 ...
How do impurities affect the boiling point of a liquid? Explain why hydrogen fluoride (HF) has a higher boiling temperature than hydrogen chloride. Define briefly: a) boiling point. b) melting point. What is the theoretical explanation for the difference between the boiling point of propane and...
Blood is a fluid present in most animals, humans included. Blood has various functions such as the transport of nutrients and the regulation of body temperature. Blood has many types of cells like plasmas and white blood cells which ...
SiH_4 molecules are heavier than CH_4 molecules, yet, according to kinetic-molecular theory, the average kinetic energies of the two gases at the same temperature are equal. How can this be possible? Which of the following are postulates of the kinetic-molecular theory of gases? 1. The d...
Can CH3CH2COOCH3 form hydrogen bonds with water molecules? Explain. Describe the bonding in SO2 and SO3 using the localized electron model (hybrid orbital theory). How would the molecular orbital model describe the [{MathJax fullWidth='false' \pi }] bonding in...
