Chapter 9, Problem 1ST

Interpretation Introduction

Interpretation:

In the reaction ${\text{2H}}_{\text{2}}\left(g\right)+{\text{O}}_{\text{2}}\left(g\right)\to {\text{2H}}_{\text{2}}\text{O}\left(l\right)$, the mass of reacting oxygen is to be predicted.

Concept Introduction:

The law of conservation of mass states that the mass of the reacting species should be equal to the mass of the product species. This means that the mass can neither be produced nor be destroyed.
