Calculate DG for the reaction CS2 +3 CL2 -> S2CL2 + CCL4 given DH =-231.1 kJ and DS= -287.6 J/k - The answer is -145.3 Kj please show work as to how they got this answer.
Is the skeleton of caffeine flat. How might the structure of caffeine account for the fact that it sublimes at atmospheric pressure instead of melting
Give the structure for an isomer of compound A that has a melting point that is appreciably different from that of A yet NMR spectra that are almost identical to those of A. Include wedge/dash bonds.
What subatomic particles contribute to the atomic mass of an atom?
