Phosphoric acid can be prepared by the reaction of P4O10 with water as given by the following balanced chemical equation. P4O10(s) + 6H2O(l) → 4H3PO4(aq) When 25.8 g of H3PO4 (98.0 g/mol) is produced, 10.9 kJ of heat is evolved. Calculate ΔH for the overall reaction.

How do cfcs cause ozone depletion? how do cfcs cause ozone depletion? ultraviolet radiation breaks down cfcs, molecules containing chlorine. chlorine then breaks one oxygen atom away from ozone, leaving behind a paired oxygen molecule. ultraviolet radiation breaks down cfcs, molecules containing chlorine. chlorine then breaks two oxygen atoms away from ozone, leaving behind a paired oxygen molecule. ultraviolet radiation creates cfcs, molecules containing chlorine. chlorine then breaks two oxygen atoms away from ozone, leaving behind a paired oxygen molecule. ultraviolet radiation creates cfcs, molecules containing chlorine. chlorine then breaks one oxygen atom away from ozone, leaving behind a paired oxygen molecule.
