Explain what is the entropy of a mixture made up of 2.4 moles of O2 as well as 9.2 moles of N2 at the same temperature and pressure? The absolute molar entropies of O2 and N2 are 205 J/K.mol as well as 192 J/K.mol respectively at 25 C
a truck driver used sand to soak up a 1 g spill of lindanec6h6cl6. he placed the contaminate soil in an open drum which
Consider a particle of mass m in a uniform gravitational field. Its potential energy is E(h) = mgh,where h is the height above sea level and g is the earth's gravitational constant, g = 9:8 m/s2.
An Al strip is placed in CuSO4 solution. Would you expect a spontaneous reaction to occur,based on the net potential
Copper (II) Iodate precipitates from iodate solution. The formula of the precipitate is Cu(IO3)2. A saturated solution of this substance was made in 0.01 M KlO3. The copper concentration was found to be 0.0012M

The chemical 5-amino-2,3-dihydro-1,4-phthalazinedione... better known as luminol, is used by forensic scientists in analyzing crime scenes for the presence of washed-away blood.
For the next three problems, consider 1.0 L of a solution which is 0.3 M HC2H3O2 and 0.2 M NaC2H3O2 (Ka for HC2H3O2 = 1.8 x 10-5). Assume 2 significant figures in all of the given concentrations so that you should calculate all of the following pH..
