How many mole...

Question

How many moles of $C O_{2}$ will be produced when $10 m o l$ $N a H C O_{3}$ is decomposed?
$2 N a H C O_{3}$ $\to$ $N a_{2} C O_{3}$ + $H_{2} O$ + $C O_{2}$

Solution

The correct option is A 5
$2 N a H C O_{3}$ $\to$ $N a_{2} C O_{3}$ + $H_{2} O$ + $C O_{2}$
From the balanced equation above, we see that 2 moles of $N a H C O_{3}$ produces $1 m o l$ of $C O_{2}$ .
When 10 moles of $N a H C O_{3}$ decomposes, $5 m o l$ $C O_{2}$ will be formed.
