The repeating unit in silicone is

Which gas is used in aerated water?

Consider the following reactions:
$Me_3SiCl \xrightarrow{H_2O} A$
$Me_2SiCl_2 \xrightarrow{H_2O} B$
$MeSiCl_3 \xrightarrow{H_2O} C$
$A$,$B$,and $C$ are known as . . . . . . , . . . . . . ,and . . . . . . respectively in silicones formation.

$P_4O_{10}$ is not used to dry $NH_3$ gas because:

In the following reaction,assign the nature of the product formed by the complete hydrolysis of the underlined atom at $R.T.$: $\underline{C}O + H_2O \longrightarrow \text{No reaction}$

Identify $X, Y$ and $Z$ in the following reaction: $2 CH_3Cl + X \xrightarrow[570 \ K]{Y} Z$
