Derive the general expression for the work per kilomole of a van der waals gas in expanding reversibly and at a constant temperature, T, from a specific volume V1 to a specific volume V2.
one day you notice that the outside temperature increase by 16 degrees Fahrenheit between your early morning jog and your lunch at noon. what is the corresponding change in temperature in the Celsius and Kelvin scales?
what are the hydrolysis by-products? What limits the reaction? What determines whether the hydrolysis reaction proceeds from cellulose to sugar (e.g. glucose) or continues on to convert the sugars to alcohol?
The relationship (if any) of the lattice energy of compounds such as ZnO vs. H3BO3 vs. their respective solubilities. For instance, at neutral pH and standard conditions
