The valve between a ten litre tank containing a gas at a pressure of 1 atm and a three lite tank containing a gas at 0.5 atm is opened. Compute the final pressure in the tank if nothing else is altered in the surroundings. (The two gases do not react)
In the molecular orbital model of the cyclopentadienyl cation, how many pairs of degenerate pi-antibonding molecular orbitals are there
Consider 3 amino acids A, B, and C. How many trimeric isomers would be formed. Show them.
Explain why there is no distinction between low and high-spin arrangements for an octahedral d8 metal ion. (b) Discuss the factors that contribute to the preference for forming either a high- or a low-spin d4 complex
If you didn't wipe away any frost or condensation formed during sublimation, how would your molar mass value be affected? Be specific please.
The work function for mercury is equivalent to 435 kj/mol photons. When light of 205nm strikes a mercury surface,the kinetic energy is 2.47x10^-19 J/photon. What is the velocity of the ejected electrons in m/s?
