Chapter 3, Problem 3.90P

(a)

Interpretation Introduction

Interpretation: Balanced equation corresponding to reaction between solid tetraphosphorus trisulfide and ${\text{O}}_{\text{2}}$ form solid tetraphosphorus decaoxide and ${\text{SO}}_{\text{2}}$ is to be shown in terms of molecules.

Concept introduction: In accordance with law of conservation of mass it is suggested total amount of reactants consumed is equal to the total amount of products formed in any balanced equation.

In order to balance an equation, one starts with the most complex chemical species and then place the appropriate coefficient so as to make the stoichiometric coefficient equal on each side.

After proper adjustment of coefficient, the atoms are checked for an equal number on each side and finally, the physical states of matter are written in parenthesis.
