WebFeb 2, 2024 · The standard enthalpy of formation of any element in its standard state is zero by definition. For example, although oxygen can exist as ozone (O 3 ), atomic oxygen (O), and molecular oxygen (O 2 ), O 2 is the most stable form at 1 atm pressure and 25°C. Similarly, hydrogen is H 2 (g), not atomic hydrogen (H). WebThe standard enthalpies of formation of ions in aqueous solutions are obtained by arbitrarily assigning a value of zero to H+\mathrm{H^+}H+ions; that is, ΔHf°[H+(aq)]=0\Delta … 富士通 bios パスワード 初期化 https://stampbythelightofthemoon.com

Standard enthalpy of formation - Wikipedia

WebThe definition of standard enthalpy of formation is the change in enthalpy when one mole of a substance is formed in its standard state from its constituent elements in their standard state at 298k and 1 atm. Since elements like Oxygen are in their standard state, there is no standard enthalpy of formation to talk about here.
