If the reaction to HGO equals 28G, plus O2 is endothermic, which bonds are the strongest
If the reaction HgO -> Hg + O2 is endothermic, it means that breaking the bonds in HgO requires more energy than is released when new bonds are formed in Hg and O2. Therefore, the strongest bonds in HgO are the ones that require the most energy to break.
In HgO, the bond between Mercury (Hg) and Oxygen (O) is an ionic bond. Ionic bonds are generally stronger than covalent bonds because they involve the transfer of electrons from one atom to another, resulting in strong electrostatic attractions between oppositely charged ions. Therefore, in this reaction, the Hg-O bond would be the strongest.
