a) $\text{S}+\text{O}{}_{\text{2}}\to \text{S}\text{O}{}_{\text{2}}$  

$\text{2}\text{S}\text{O}{}_{\text{2}}+\text{O}{}_{\text{2}}\to \text{2}\text{S}\text{O}{}_{\text{3}}$  

$\text{S}\text{O}{}_{\text{3}}+\text{H}{}_{\text{2}}\text{O}\to \text{H}{}_{\text{2}}\text{S}\text{O}{}_{\text{4}}$  

$\text{S}\text{O}{}_{\text{2}}+\text{H}{}_{\text{2}}\text{O}\to H{}_{\text{2}}\text{S}\text{O}{}_{\text{3}}$

 

b) 

$\text{4}\text{P}+\text{3}\text{O}{}_{\text{2}}\to \text{2}\text{P}{}_{\text{2}}\text{O}{}_{\text{3}}$  

$\text{P}{}_{\text{2}}\text{O}{}_{\text{3}}+\text{O}{}_{\text{2}}\to \text{P}{}_{\text{2}}\text{O}{}_{\text{5}}$  

$\text{P}{}_{\text{2}}\text{O}{}_{\text{5}}+\text{3}\text{H}{}_{\text{2}}\text{O}\to \text{2}\text{H}{}_{\text{3}}\text{P}\text{O}{}_{\text{4}}$
