Below you will see labels for several products commonly used in daily life. Using only a periodic table, locate fifteen compounds in the given products of which you can determine the chemical formula. Write what product(s) it is found in (if found in multiple products list all), and the chemical name in the ingredients list on the package. Determine the chemical formula and whether it is an ionic or covalent compound. Some compounds will be written in an improper chemical way, please correct the name if needed. You must find at least one acid and one covalent compound. You may search for additional, similar product labels.
Scoring: 1 point for every correct formula and classification; +1 for every corrected name
