Chapter 7.7, Problem 7.53PP

Write all of the mole—mole factors for each of the following chemical equations:

a. ${\text{2SO}}_{\text{2}}\left(g\right)+{\text{O}}_{\text{2}}\left(g\right)\to {\text{2SO}}_{\text{3}}\left(g\right)$
b. $\text{4P}\left(s\right)+\text{5O2}\left(g\right)\to {\text{2P}}_{\text{2}}{\text{O}}_{\text{5}}\left(s\right)$
