Show, with the aid of a form of the Nernst equation that when using a pH sensitive glass electrode and reference electrode that the measured potential is proportional to pH.
What is the pH of a 0.30 M pyridine solution that has Kb=1.9x10^-9? the equation for the dissociation of pyridine is C5H5N5(aq)+H2O(l) >>> C5H5NH(aq)+OH-(aq).
what is the ph after 45.0ml of .1M HCl is added during the titration of 30.0ml of 0.1 Mweak base that has a (kb=5.2 *10^-4)

How many grams of methane must be combusted to heat 1.15 of water from 26.0 to 87.0, assuming as a product and 100% efficiency in heat transfer?
Why is it more difficult to identify all of the components of a mixture than it is to identify the cation and anion that make up a simple salt
Describe two independent methods for determining the atomic mass of an element. Explain how these method are truly independent.
Illustrate this by showing the reaction of trans-p-anisalacetophenone with bromine and 2,4-dinitrophenylhydrazine to give the corresponding products
Three isotopes of silicon occur in nature: 28Si (92.21 %) which has a mass of 27.97693 amu; 29Si (4.70 %) which has a mass of 28.97659 amu; and 30Si (3.09 %) which has a mass of 29.97376 amu. Calculate the average atomic mass for silicon atom.
Assuming constant pressure, rank these reactions from most energy released by the system to most energy absorbed by the system, based on the following descriptions
