What is the correct net ionic equation, including all coefficients, charges, and phases, for the following set of reactants? Assume that the contribution of protons from H2SO4 is near 100
Draw all possible stereoisomers for each of the following compounds. If no stereoisomers are possible, only draw one structure. (All hydrogen atoms are implied. If a chiral carbon atom is attached to a hydrogen atom
Write the structure for the pyrrolidine enamine and for the imine of cyclohexane. Write a balanced equation for the acid-catalyzed hydrolysis of each of these compounds.
the volume of a sample of oxygen gas collected over water is 258 mL at 27 degrees C and 620.0 torr. Calculate the volume in milliliters of dry oxygen gas at STP. (the vapor pressure of water at 27 degrees C is 26.7 torr.)
At a certain temperature and pressure 2.8 L of N2 reacts with 4.2 L of O2. If all the N2 and O2 are consumed, what volume of N2O3, at the same temperature and pressure, will be produced
