Interpretation Introduction

(a)

Interpretation:

The balanced equation for the reaction of treatment of finely divided gold with CN-(aq) in the presence of O2 (g) should be written.

Concept introduction:

The balanced chemical equation can be written by following a few steps:

Step 1: Writing the correct skeleton and molecular formula for the element or molecules on either side of the equation.

Step 2: Counting the number of atoms of each element on either side of the equation.

Step 3: Balancing the number of that atom or group on either side which has large atoms in number.

Step 4: Using the correct coefficients to balance the number of atoms on both sides.

The U. S. Environmental Protection Agency (EPA) sets limits on healthful levels of air pollutants. The maximum level that the EPA considers safe for lead air pollution is 1.5 μg/m3 . If your lungs were filled with air containing this level of lead, how many lead atoms would be in your lungs? (Assume a total lung volume of 5.40  L
