Question

so2+pcl5

Answer 1

$\text{SO}_2 + \text{PCl}_5 \rightarrow \text{SOCl}_2 + \text{POCl}_3$

Answer 2

We write the reaction between sulfur dioxide and phosphorus pentachloride as:

$$\text{SO}_2 + \text{PCl}_5 \rightarrow \text{SOCl}_2 + \text{POCl}_3$$

The reaction is balanced since:

• S: 1 on both sides
• O: 2 on both sides (1 in $\text{SOCl}_2$ and 1 in $\text{POCl}_3$)
• P: 1 on both sides
• Cl: 5 on both sides (2 in $\text{SOCl}_2$ and 3 in $\text{POCl}_3$)
