Vedclass · Answer

(A) Statement $1$ is correct because heavy water $(D_2O)$ slows down metabolic rates and is harmful to living organisms.Statement $2$ is incorrect because the reaction of aluminum carbide with heavy water produces deuterated methane $(CD_4)$,not acetylene: $Al_4C_3 + 12D_2O \rightarrow 4Al(OD)_3 + 3CD_4$.Statement $3$ is correct as $BaCl_2 \cdot 2D_2O$ is a known example of an interstitial deuterate where $D_2O$ molecules occupy interstitial sites in the crystal lattice.Therefore,the correct statements are $1$ and $3$.

Observe the following statements:
$1.$ Heavy water is harmful for the growth of animals.
$2.$ Heavy water reacts with $Al_4C_3$ and forms deuterated acetylene.
$3.$ $BaCl_2 \cdot 2D_2O$ is an example of interstitial deuterate.
The correct statements are:
