Determine How many grams of Oxygen are needed to combine with 7.70 moles of Ammonia?
An optimization from a particular starting structure of a compound C5H10O2 leads to an energy of 25.12 KJ/mol.
Sodium atoms emit light with a wavelength of 330 nm when an electron moves from a 4 p orbital to a 3 s orbital. What is the energy difference between the orbitals in kilojoules per mole?
Some species with two oxygen atoms only are the oxygen molecule, O2, the peroxide ion, O2-2 , the superoxide ion, O2-1 , and the dioxygenyl ion, O2+1 . Draw an MO diagram for each, rank them in order of increasing bong length, and find the number ..
If 10.0 mL of 0.00200 M KNCS is mixed with a very large excess of Fe(NO3)3, how many moles of FeNCS2+ product should form
Kp for this reaction is 5.1 x 10-2 atm-1. Initially, 1.00 g each of SO2 and Cl2 are placed in a 1.00 L reaction vessel. After 15 minutes, the concentration of SO2Cl2 is 45.5 μg/mL.
why during a GC is the boiling point for some samples higher than the final temperature used during the run yet these samples still run
Write the net ionic reaction from the following balanced reactions: 1. FeCl3 (aq) + K3PO4 (aq) = FePO4 (s) + 3 KCI (aq) 2. Ba(NO3)2 (aq) + Ag2SO4 (aq) = 2 AgNO3(aq) + BaSO4 (s)
Calculate the percentage of acetic acid that exists in ionized form when dissolved in water at 0.5 M total concentration.
The pressure of the gas remaining in the vessel of unknown volume was 0.882 atm. All the measurements were done at the same temperature. What is the volume of the vessel?
five times in the course of parts a-d of this experiment you were able to dissolve an "insoluble" compound, something that seems like a contradiction in terms, identify each of the 5 compounds and briefly explain what made each of these dissolutio..
