What are the possible values of n and ml (the principal and angular momentum quantum numbers) for an electron in a 5d orbital?
A solution contains 0.010 M silver ion and 0.0010 M lead(II). Sodium sulfate is dissolved to give a nominal concentration of 0.0010 M sulfate. Does a precipitate form?
Enzyme X is a highly pigmented protein that imparts the characteristic color to certain blue-green algae. It also facilitates a reaction necessary to the survival of this species; we can follow the kinetics of this reaction by measuring the conver..
a solution of water kb0.512 c and glucose freezes at 4.15. what is the molal concentration of glucose in this solution?
the temperature of the solution increases to 26.5 C. Calculate the enthalpy change, Delta H, for this reaction per mole of X. Assume that the specific heat and density of the resulting solution are equal to those of water
If you were to repeat the experiment at the elevation of 7700 ft, what change, if any, would there be in the amount of boiling ethanol needed to dissolve the impure naphthalene
which of the solutions included in this experiment could be used to distinguish between the pairs of solutions. In each case, describe the observations you would make and write a net ionic equation for any reaction that would occur.
Calculate the molar concentration of HCl in a solution that has a specific gravity 1.185 and is 36.5% (w/w). Prepare from this bottle 1 L of 0.1 HCl solution. 25 mL of this solution titrated with 30 mL of NaOH.
The normal boiling point for acetone is 56.6 degrees Celsius. At an elevation of 5300 ft the atmospheric pressure is 630 torr. What would be the boiling point of acetone (enthalpy of vaporization=32.0 kj/mol) at this elevation? What would be the v..
The rate of bacterial hydrolysis of fish muscle is twice as great at 2.2 degrees C as at -1.1 degrees C. Determine the activation energy for this reaction.
