Determine the delta G associated with the dissociation of 5.0g of C76H52O46 at room temperature in 50mL of pH=7.55 buffered solution that has already had 2.5g C76H52O46 dissolved into it.
Calculate the gas NH3 in ppm over NH4OH solution.The density of the solution is 0.9g/ml and the Commercial concentrated aqueous ammonia is 29%.
olutions of sucrose (table sugar, C12H22O11) are used in high speed centrifuges to separate the parts of a biological cell. How many liters of 3.53 M sucrose contain 111 g of solute
Use the van der Waals equation of state to plot the compressibility factor, Z, against P for methane at 180K and 250K. Hint: calculate Z as a function of V/n and P as a function of V/n, and then plot Z Vs. P.
Explain how and why Carbon can experience, sp, sp2, and sp3 via hybridization and what role this plays in the geometry of the molecule.
The oxygen atom (with its 2s orbital) forms a s bond with one of the three sp2 hybrid orbitals of the carbon atom; the two hydrogen atoms (with their 1s orbitals) each form a s bond with one of the three sp2 hybrid orbitals of the carbon atom.
