Draw two molecules that are diastereomers and calculate the energy of each.Then draw two molecules that are enantiomers and calculate the energy of each. (You may use the same molecule twice). Comment on how the results agree or do not agree with theory.
Determine what amount of heat is required to increase the temperature of sixty grams of ethylene glycol from 15.1 degree Celsius to 40.3 degree Celsius?
Calculate the cell potential for the following reaction as written at 61 °C, given that [Mg2 ] = 0.854 M and [Ni2 ] = 0.0100 M. If Mg(s)+Ni^2+ Mg^2+ + Ni(s). E^o for Mg half-cell is -2.38 and for Ni -0.26
Draw resonanc contributors for the following species. Indicate which are major contributors and which are minor contributors to the resonance hybrid:
How is it possible for temperatures below the ice to be actually warmer than surface temperatures
The contents of the tank are transferred without loss to an evacuated 55 L tank in scold room where the temperature is 4 degree C . What is the pressure in the tank ?
Three manufacturers are producing carbonated bottled water. One company introduces carbonate by bubbling carbon dioxide into water until CT=10-3 M (equivalent to adding "H2CO3*" until CT = 1 x 10-3 M), a second adds sodium bicarbonate (NaHCO3) unt..
For each of the five principles of biochemistry give an example(step or series) from a biochemical pathway that satisfies each principle
Liquid helium at 4.2 K has a density of 0.147 g/mL. Suppose that a 1.00-L metal bottle that contains air at 98K and 2.0 atm pressure is sealed off. If we inject 60.0 mL of liquid helium and allow the entire system to warm to room temperature
what is the minimum number of moles of sodium hydroxide required of this hydrolysis reaction to go to completion and what is the limiting reagent in this experiment?
Originally, 1.0 mL Hydrochloric acid is added to 1.0g of an unknown amine and 28 mL water in the first step of the Synthesis of Acetamides. If we added 3X the amount of hydrochloric acid instead, why would there be no product?
what is the volume in milliliters of 20.0 g of acetone if the density of acetone is .791 g/ml?
At 40°C, the vapor pressure of heptane is 92 torr. If a solution is made of naphthalene in heptane and has a vapor pressure of 82 torr, what is the mole fraction of naphthalene? Assume ideal solution behavior.
