Use the chemical equation and the bond diagram to answer the question. H2 + O2 → H2O2

H–H + O=O → H–O–O–H

The energy of the H–H bond is 432 kJ/mol. The energy of the O=O bond is 495 kJ/mol. The energy of the O–H bond is 467 kJ/mol. The energy of the O–O bond is 146 kJ/mol.

Which bond is the strongest?

O=O

O–H

H–H

O–O

Darla claims that the first periodic table developed by mendeleev was not completely accurate, so it is not useful at all. harmony argues that it establish the periodic table we use today, making it more credible. who is correct and why? darla is correct, because a model that has any mistakes should be thrown out. darla is correct, because a good model would not need to change. harmony is correct, because mendeleev’s model had all of the information correct in the first version. harmony is correct, because mendeleev’s model made predictions that came true.
