) The dissociation energy (from the zero-point level) of ground-state O2 is 5.09 eV. There exists an electronically excited state of O2 whose zero-point level lies 6.21 eV above the zero-point level of the ground state. The ground-state molecule dissociates into two ground state O atoms, while the excited state of O2 dissociates into one O and one O* (electronically excited) atom. O* lies 1.97 eV above O. Sketch the potential energy curves and calculate the dissoc

Hbr dissociates to form h+ and br-ca(oh)2 dissociates to form ca2+ and 2oh-the h+ and oh- react to form waterassuming the reactants are dissolved in water, the net reaction is h+ + oh- —> h2oif you’re asked to show all components of the reaction, the complete reaction is 2hbr + ca(oh)2 —> cabr2 + 2h2o

Mg-26 and mg-24 are pair of isotopes. isotopes are defined as atoms of the same element having same atomic number but different mass number. i hope that was .
