NTA AbhyasNTA Abhyas 2022
Solution:
(i) Ice formed by heavy water sinks in normal water due to higher density of $D_{2}O$ than normal water
(ii) $6CO_{2}+6H_{2}O\xrightarrow{hv \text{chlorophyll}}C_{6}H_{12}O_{6}+6O_{2}$
(iii) Water can show amphiprotic nature and hence water can act both as an acid a base
(iv) There is extensive intermolecular hydrogen bonding in the condensed phase instead of intramolecular H-bonding
