3. Corev 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? 4A 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?
Does the amount of activated carbon used in the purification process important? O Yes. Since activated carbon adsorbs all compounds, the amount used should be increased, as this may result in a higher recovery of the desired compound. O No. Since activated carbon adsorbs all compounds to some degree, the amount used should be reduced, as this may result in a higher recovery of the desired compound. O Yes. Since activated carbon adsorbs all compounds to some degree, the amount used should be reduced, as this may result in a lower recovery of the desired compound. O No. Since activated carbon adsorbs all compounds, the amount used is not important, as this does not affect in the recovery of the desired compound.
