randk the following solutions in order of increasing pH of their 0.1M aqueous solutions - KNO3, K2SO3, K2S
The energy for the process (H)+(energy) yields (H+)-(e-) is called the ionization energy of hydrogen. The experimentally determined value for the ionization energy of hydrogen is 1310 kJ/mol. How does this compare to your calculation
A gas mixture composed of helium and argon has a density of 0.719g/l at a 743mmHg and 298k . What is composition of mixture by volume?
Assuming an Sn1 reaction mechanism, predict the major organic product(s) of (s)-3,3-dimethy-2-butanol reacted with HCl.
Concentrated aqueous HClO4 has a concentration of 14.8 M. Calculate the concentrations of all ions present in a solution prepared by pipetting 4.19 mL of concentrated HClO4 into a 1000. mL volumetric flask and filling to the mark.
60.0 mL portion of of 1.70 M solution is diluted to a volume of 288 mili litres. A 144-mili litres portion of that solution is diluted using 115 mLili litres of H2O. Determine the final concentration.
What are the relative populations of these levels at the boiling if the degeneracy level is 2j+ 1? Is the ground state most highly populated level?
The pH of 0.750 M sodium hypochlorite, NaClO, is 10.72. What is the pKb for this base?
What percentage error would be introduced in a 35.0 mL sample of liquid if the air bubble comes out of the tip of the buret while the liquid sample is being transferred?
calculate the pKa value of the acid and determine the number of moles of acid initially present.b) when the reaction is complete, what is the concentration ratio of conjugate base to acid?
Lysine is an amino acid that is an essential part of nutrition but which is not synthesized by the human body.
Propose a step-by-step microscale extraction procedure that could be used to separate a mixture nitrobenzene, 4-methoxybenzoic acid, and benzylamine into the pure compounds using extraction technique.
Calibration and collection of equilibrium data are different experiment. Why could you use the calibration curve for getting equilibrium data?
