Enthalpy is a measure of the heat of reactions, meaning this {eq}\Delta H {/eq} is actually the difference between the enthalpies of the products and the reactants (in other words, the difference between the energy of bond formation and the energy bond breaking): ...
Heat capacity: 40.26 J/mol °C at 25 °C; Enthalpy of formation: -356.1 kJ/mol at 419.5-907 °C; coefficient of expansion: 4.0X10-6 1/deg C; conductivity: 25.2 W/m K|Zinc oxide, as an amphoteric material, reacts with acids to form zinc salts and with strong alkalies to form zi...

Before the chemists try experimentally the synthesis of new compounds, they calculate theoretically the enthalpy of formation using the heat of combustion of all the reactants involved in the reaction. Example: 1 g of glucose is submitted to combustion in a calorimetry and the temperature increase...
