How does [HCl] Affect the Change in Temperature at Constant Volume in NaOH Solution? What kind of relationship? Linear or power or exponential etc.
Discuss the two main mechanisms in nucleophilic substitution reactions. Provide examples, show reaction diagrams, discuss controls of reaction rates, stereochemistry
In which state is the average distance between molecules the greatest?, Explain the difference in densities at the two temps in terms of the kinetic molecular theory.
Calculate the work done (in J) on the surrounding atmosphere (1atm pressure, 25.5 oC ) by the evolution of hydrogen in the subsequent reaction. State any assumptions you have made.
The % ionization of a weak acid always declines in a solution that contains the salt of the anion relative to a solution of the acid alone. For example the % dissociation of the acetic acid is less in a solution that contains sodium acetate than i..
