Textbook Problem

The reaction between potassium chlorate and red phosphorus takes place when you strike a match on a matchbox. If you were to react 52.9 g of potassium chlorate (KCIO₃) with excess red phosphorus, what mass of tetraphosphorus decaoxide (P₄O₁₀) could be produced?

${\text{KClO}}_3\left(s\right)+{\text{P}}_4\left(s\right)�{\text{P}}_{\text{4}}{\text{O}}_{\text{10}}\left(s\right)+\text{ KCl}\left(s\right)\left(\text{unbalanced}\right)$
