question_answer 1)

Knowing the properties of \[{{H}_{2}}O\] and \[{{D}_{2}}O\], do you think that \[{{D}_{2}}O\] can be used for drinking purposes?  

Answer:

Heavy water, i.e., \[{{D}_{2}}O\] does not support life and is injurious to human beings, animals and plants as the chemical reactions are slow in heavy water. Metabolism disorders may occur, thus heavy water is not fit for drinking.
