21. These modes include stretching and bending motions of the chemical bonds of the molecule. 22. Maximum bond strength results from effective overlap of atomic orbitals in a chemical bond . 23. An oxidizing bleach works by breaking the chemical bonds that make up the chromophore. 24. Attachment is supported by weak chemical bonds between the attachment and the receptor site. 25. Hence energy is required to form chemical bonds via condensation. 26. The states of matter, ions, chemical bonds and chemical reactions. 27. These molecules are held together by chemical bonds that your body has trouble breaking. 28. The energy is then adsorbed as the chemical bonds from the sucrose break down. 29. This arrangement may be the result of chemical bonds within a molecule or otherwise. 30. Partial charges are created due to the asymmetric distribution of electrons in chemical bonds .
