Question

Complete the given reaction.
$KN{O}_3\left(s\right)\underset{}{\overset{\Delta }{\to }}KN{O}_2\left(s\right)+$$\left(g\right)$

• A. $O_2$
• B. $NO$
• C. $N{O}_2$
• D. $\left[O\right]$

Answer 1

The correct option is A $O_2$

$KN{O}_3$ under thermal decomposition produces $KN{O}_2$ and $O_2$ gas.
$2KN{O}_3\left(s\right)\underset{}{\overset{\Delta }{\to }}2KN{O}_2\left(s\right)+O_2\left(g\right)$
