What is the important component in 1.0 M NaOH? What is the important component in 1.0 M HCl
what is the appropiate mechanism for the radical polymerization of 1-butyne? show the polymerization of three units of 1-butyne.
what Kelvin temperature will the vapor pressure be 3.00 times higher than it was at 329 K?
How much heat is given off when 11.0 grams of manganese is converted to Mn2O3(s) at standard state conditions? Hf of Mn2O3(s) is -962.3 kJ/mol.
External fields (such as those generated by a laser) can couple electronic states together. By a well-chosen laser pulse, an H atom is created in an equal superposition of the 1s and 2p0 states.
The average kinetic energy of the molecules in a gas sample depends only on the temperature, T. But given the same kinetic energies, a lighter molecule will move faster than a heavier molecule.
Use heat of formation data to determine H for the combustion of hydrogen sulfide according to the following reaction: 2 H2S(g) + 3 O2(g) ? 2 SO2(g) + 2 H2O(?) ?H = ? ?Hfo for compounds:
How many grams of sodium fluoride should be added to prepare the buffer solution? Neglect the small volume change that occurs when the sodium fluoride is added.
A researcher conducts an experiment to determine the work function of a palladium surface. She fires a laser with a wavelength of 254 nm at a certain time and observes electrons hitting a detector
At equilibrium, 0.11 mole of CO2 was present. Calculate the equilibrium constant Kc of this reaction.
Assuming that the Pauli exclusion principle remains valid in the distant universe, what is the maximum number of electrons that can populate a given orbital there.
is an important oxidizing agent and a moderately strong acid. in a 0.1M solution ,[H+] = 3.8x10^-2M. Calculate the Ka and the pKa for periodic acid.
