Write the balanced chemical equation for the reaction of solid tetraphosphorus hexoxide with water. I know the answer (because of the book) is P4O6(s) + 6 H2O(l) --> 4H3PO3(aq). What I don't understand is how they got it. I know that tetraphosphorus hexoxide is P4O6 and water is H2O. What I don't understand it how it becomes 4H3PO3.
