A 407 container placard guide page is 119. What does this mean? The product is a _________.

Explanation:
Understanding how placard guides are read helps you identify the substance form from the code on the container. In this system, the placard code points you to a specific form in the guide’s pages. When the cross-reference for that code shows monomer, the product is a monomer—a single molecule that can react with other units to form polymers. So, the substance is a monomer because the guide’s linkage for that placard code identifies the material as a single-unit molecule, not a polymer, oligomer, or dimer. A polymer would be many units linked together, an oligomer is a short chain of a few units, and a dimer is simply two units.
