Explain the relevance of numbers of molecules to volume, density and relative molecular mass.
In detail please
(a) Explain the difference between solubility and solubility product constant. Write the expression for the solubility-product constant for each of the following ionic compounds:MnCO3, Hg(OH)2, and Cu3(PO4)2.
If a process is carried out at constant pressure P and the volume V of the system decreases, then is delta V negative or positive and is the work w negative, positive, or zero
Problem- A solution of H2SO4 with a molal concentration of 1.94m has a density of 1.119g/mL. What is the molar concentration of this solution
the rate of bimolecular reaction is affected by concentrations of reactants presence of a catalyst and temperature, Concentration of a pure solid and a liquid can be ommitted from the equilibrium equation as the concentration ratio of these equal to..
Calculate the equilibrium constant KP if the total pressure is 2.6 atm at that temperature.
You dilute 1g of the soap 1:106 and plate it on standard plate count agar. After 24 hours of incubation, there are 168 colonies. How many bacteria were on the soap? How did they get there?
An alkyne of six carbon atoms gives the same single product in its reaction either with BH3 in THF followed by H2O2 /OH-, or with H2O/Hg2 /H3O . Draw the structure of the alkyne (containing only carbon and hydrogen atoms).
Balance the subsequent redox equation, using half-reactions. Presume that the reaction occurs in an aqueous solution.
How many pi bonds and sigma bonds does the chemical compound caffeine has, and where can one get some information on hybrid orbitals on aromatic compounds like benzene and caffeine
Find the pH of the equivalence point and the volume (mL) of 0.0740 M KOH needed to reach the equivalence point in the titration
Consider an experimental run at 273 rm K where the initial number of moles (n_1) is actually 1.00 rm mol, and the final number of moles (n_2) is 2.00 rm mol.
1. during the titration several milliliters of deionized water are added to the erlenmeyer flask containing the khp
