6M NH3, a basic solution, cannot be found on the reagent shelf, but 6 M NaOH, also a base, is available. What would be observed if the 6 M NaOH is substituted for the 6 M NH3 in testing the reference solution? Explain
A sample of gas is compressed from 13.01 L to 4.27 L using a constant external pressure of 3.63 atm. At the same time, 1,453 J of heat flows into the surroundings. What is the internal energy change for the gas
Explain the order of elution you observed while performing the gas chromatography for this experiment. What property of the product molecules seems to be the most impor- tant in determining relative retention times?
There are very few compounds that contain an element from the noble gas family (elements in column 18, rightmost column). Explain why there are so few noble gas compounds in nature.
What is the number of moles of atoms of oxygen contained in 49 grams of sulfuric acid, H2SO4?
The overall formation constant for Cu(NH3)42+ is 1.1x1013 at 25oC. What is [Cu2+], in moles per litre, at equilibrium when 8.3 g Cu(NO3)2 is dissolved in 0.500 L of 1.00 mol/L NH3(aq)? Assume that there is no volume change when the Cu(NO3)2 is add..
