Use Delta_fus H = 6.01 kJ/mol at 0 degree C for the sold rightarrow liquid phase transition of water to calculate Delta_fus S. The Calculated answer is J/mol K (1 decimal place.) The solubility of thallium chloride (TlCl) in water is 0.29 g in 100. mL of solution at 15.6 degree C. The molar concentration of Ti^+ is M (4 dec places). The molar concentration of Cl^- is M(1 dec places). The K_sp for TlCl at this temperature is (1...

Given rms speed, c = (3 RT/M)^1/2 Determine the temperature and pressure of 3.01 times 10^23 gas molecules, each with a mass of 6.64 times 10^-26 kg, in a 5 times 10^-3 m^3 container if the rms speed is 560 m/s. These molecules are distributed in 2 states with energies of 0 and 5 epsilon (epsilon =1.381 times 10^-21 J). There is no degeneracy for the first level. The second level is doubly degenerated. Calculate number of molecules in each...
