Just as travelogs are not atlases or sociohistorical treatises and raconteurs do not need tape recorders or photographic memories, the philosophy is that chemical understanding normally does not take the form of axioms or even theorems. It is hoped that reading this column will prove as educational...

The standard enthalpies of formation of CO2 (g) and H2O (l) are -393.5 kJ/mol and -285.8 kJ/mol. Given the standard enthalpy change of the following reaction, calculate the standard enthalpy of format Calculate the standard enthalpies of formation ...
A standard enthalpy of formation, ΔHf° (C10H24N6O6Cu(c)) = -639.4 ± 4.0 kJ mol-1, was derived from the experimental data and was used, together with enthalpy of solution data, to derive the enthalpy of formation of the complex ion in aqueous solution. This latter value was in ...
