For this reaction to proceed, the following bond breaking should occur: *one C-O bond* one H-Cl bond After, the following bond formations should occur:*one C-Cl bond*one O-H bond Now, add the bond energies for the respective bond energies which can be found in the attached picture. For bond formations, energy is negative. For bond breaking, energy is positive. ΔHrxn = (1)(358) + (1)(431) + 1(-328) + 1(-463) =<em> -2 kJ</em>
A solar eclipse occurs when a portion of the Earth is engulfed in a shadow cast by the Moon which fully or partially blocks sunlight. This occurs when the Sun, Moon and Earth are aligned. Such alignment coincides with a new moon indicating the Moon
