derivation of ideal gas equation for a monatomic gas
Derive the ideal gas equation for a monatomic gas.
why do some elements exist as molecules
Read the following taken from a chemistry book: Scientists analysing tables of gases containing following headings /name of gas / formula / ram / average speed at 25 deg celsius / realised that the particles in a sample of hydrogen gas do not move fast enough to be single individual atoms these atoms are combined to form mole ...continues
Standard Enthalpies of Reaction
50 g of C16H34 are burned with insufficient oxygen for complete combustion to CO2. C16H34(s) + 16.5 O2(g) -> 16 CO(g) + 17 H2O(l) and some of the reaction forms CO2 and H2O(l) in the reaction C16H34(s) + 24.5 O2(g) -> 19CO2(g) + 17H2O(l) (P=1 bar, T=298.15K, heat change = -1945.2 kJ) 1. Compute percent C16H34 that reacted ...continues
Calculate the ratio of HCL molecules in the first excited rotational state to those in the ground state @ 25 C. Assume an equilibrium bond distance of 1.275 angstroms. the angstrom part of the problem throws me off, I usually start these out by solving Change in E = ( h ) ( c )(Wo), but this is a q (rot) prob, not a q (el ...continues

Use a Slater determinant to derive the ground-state wave function for Lithium (Li).
Use of a trial function to calculate ground state energy
Attached is problem, not familiar with trial functions for physical chemistry (attachment includes complete equations). --- Use a trial function of the form = e to calculate the ground state energy of a quartic oscillator, whose potential is V(x) = cx ^ 4 . ---
Derive the expression for the entroy change, delta S, for a reversible, isothermal expansion of a van der waals gas from volume 1 to volume 2.
