1.	Account for the following :(a) H3PO4 is preferred to H2SO4 in preparation of H2O2 from BaO2.8H2O (b) Water is responsible for moderation of the climate and the body temperature of living beings (c) Melting point of D2O is higher than normal water .
Answer» a) Because H₃PO₄ act as negative catalyst and prevent the decomposition of H₂O₂ b) Water has high heat of vapourisation and freezing due to hydrogen bond c) Deuterium is larger than hydrogen and hence strong hydrogen bonding
