Chapter 3, Problem 3.143QE

Interpretation Introduction

Interpretation:

A $\text{2}\text{.24g}$ sample of an unknown metal reacts with $\text{HCl}$ to produce $\text{0}\text{.0808g}$ ${\text{H}}_{\text{2}}$ gas.  The reaction is $\text{M+2HCl}\stackrel{}{\to }{\text{MCl}}_{\text{2}}{\text{+H}}_{\text{2}}$.  The metal has to be identified by assuming the percent yield of product as $\text{100\%}$.

Concept Introduction:

The mass of a product isolated from a reaction is known as the actual yield.  The actual yield of a product, the result of a laboratory experiment is less than the theoretical yield and is expressed as percent yield.
