WebbA uni-univalent electrolyte is one that dissociates into two univalent ions. Molar enthalpy of solution is the enthalpy change when 1 mol of solute in its standard state is dissolved in … WebbThere are two kinds of enthalpy of combustion, called high (er) and low (er) heat (ing) value, depending on how much the products are allowed to cool and whether compounds like H 2O are allowed to condense. The high heat values are conventionally measured with a bomb calorimeter. Low heat values are calculated from high heat value test data.

For example, the standard enthalpy of combustion of ethane gas refers to the reaction C2H6 (g) + (7/2) O2 (g) → 2 CO2 (g) + 3 H2O (l). polisimia
