Calculate the work in kilojoules done during a synthesis of ammonia in which the volume contracts from 7.6 L to 4.6 Lat a constant external pressure of 41atm.
(a) Can you suggest a reason that accounts for this unusual behavior? (b) Suggest an experiment with labeled compounds that would confirm this mode of attack.
Container A holds 727 mL of ideal gas at 2.20 atm. Container B holds 134 mL of ideal gas at 4.20 atm. If the gases are allowed to mix together
A gaseous compound containing carbon and hydrogen was analyzed and found to consist of 83.65% carbon by mass. What is the empirical formula of this compound
what pressure would it exert? (b) What pressure would it exert if it behaved as a van der Waals gas?
What is the optical purity, or enantiomeric excess, of the 2-octanol produced in this reaction? 10% S. What is the ratio of enantiomers of 2-octanol in the product mixture
write the skeleton equation representing the heating of magnesium carbonate to produce solid mangnesium oxide and carbon dioxide gas.
What is the molarity of the HCl solution if 270 mL of the HCl solution reacts with magnesium to produce 7.40 L of H_{2} gas measured at STP.
Use the Boltzmann equation to calculate the excited-state and ground-state population ratio for HCl (g*/g0=1) at room temperature (25 oC). The frequency of the absorption from the ground to the excited state is 2885 cm-1. What is the population ra..
