Chapter F, Problem H.16E

(a)

Interpretation Introduction

Interpretation:

Balanced chemical equation for reaction of pentaborane with oxygen resulting in formation of ${\text{B}}_{\text{2}}{\text{O}}_{\text{3}}$ and liquid water has to be written.

Concept Introduction:

Chemical equation is a short form representation of a chemical reaction with all the required conditions necessary for the reaction to take place.  As the atoms are neither created nor destroyed in a chemical reaction, the number of atoms of same element has to be equal on both sides of the equation.  This is known as balanced chemical equation.  Coefficients can be changed but not the subscript.

(b)
