Question

$Si{F}_4+H_{2}O\to A\stackrel{{1000}^{o}C}{\to }B\stackrel{N{a}_{2}C{O}_3}{\to }C$

In the above reaction, identify B and C respectively :

• A. $H_{4}Si{O}_4$ and $N{a}_{2}Si{O}_3$
• B. $Si{O}_2$ and $N{a}_{2}S$
• C. $Si{O}_2$ and $N{a}_{2}C{O}_2$
• D. $Si{O}_2$ and $N{a}_{2}Si{O}_3$

Answer 1

The correct option is D $Si{O}_2$ and $N{a}_{2}Si{O}_3$

The reactions are as follows:
$Si{F}_4+H_{2}O\to Si(OH{)}_4\stackrel{{1000}^{o}C}{\to }Si{O}_2\stackrel{N{a}_{2}C{O}_3}{\to }N{a}_{2}Si{O}_3$

Hence, option D is the correct one.
