Vedclass · Answer

(A) The statement '$CO$ is used in the manufacture of Urea' is incorrect. In the industrial production of urea,$NH_3$ and $CO_2$ are used as raw materials,not $CO$. The reaction is: $2NH_3 + CO_2 \rightarrow NH_2CONH_2 + H_2O$. Quartz is indeed a piezoelectric material. Silicones are synthetic polymers used as electrical insulators due to their high thermal stability and water-repellent nature. $ZSM-5$ is a type of zeolite catalyst used in the petrochemical industry to convert alcohols directly into gasoline.
