3. Corey was synthesizing a chemical in the laboratory. He used different purification
techniques to try to obtain a pure compound. The melting point of the pure compound is 65
degrees. When he tested his compound in the lab the melting point he obtained was 62-68
degrees. Is the product he synthesized pure?
4. A company was low on copper metal and decided to use some chemical additives just this
once to some copper wiring they were installing in a house. How will this impact the
conductivity of the wiring?
