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.
What is the coordination geometry about the vanadium ion incrystals of the alum? Write balanced equations for each reduction step. Assuming an average current of 1.75amps is passed during theelectrolysis, calculate how long it would take to reduce ..
Suppose you inserted a piece of copper into a solution of nickel chloride and observed no reaction. Then if you inserted a piece of iron into the solution of nickel chloride a nickel deposit formed on the bottom of the well in the well plate.
How many grams of butane must be burned to provide the heat needed to melt a 85.0-g piece of ice (at its melting point) and bring the resulting water to a boil (with no vapourization)? Assume a constant pressure of 1 bar and use the following data
How many electrons are transferred between the cation and anion to form the ionic bond in one formula unit of each compound? (1 electrons, 2 electrons, 3 electrons, 4 electrons)
1.00 mol Zn reacts with excess hydrochloric acid, 1.00 mol H2 gas is produced. At 25ºC and 1.00 atm= 101,325 Pa, this amount of H2 occupies 24.5 L (= 24.5 x10-3 m3). How much work is done by the chemical system.
A given mass of air occupies 900 ml at one atmosphere (760 mm) of pressure. What pressure must be applied to reduce the volume to 700 ml at constant temperature
How many milliliters of a 0.150 M magnesium hydroxide solution are needed to neutralize 1.985 L of a hydrochloric acid solution that is 0.5408 M
A 500 L tank contains 525 moles of propane at 100°C. The critical point for propane is 369.9K and 42.0 atm. Calculate the tank pressure (absolute) using the Virial Equation (1st order). Note: ? = 0.152 for propane.
