Answer:
The correct answer is "Swap the uses for iron oxide and calcium carbonate".
Explanation:
Giovanni's chart can be summarized as follows:
- Sodium Hydroxide (NaOH): Plastic, soap, and paper production
- Iron oxide (FeO): Toothpastes and antacids
- Calcium chloride (caCl2): Snow removal
- Calcium carbonate (CaCO3): Dark pigment in makeup
It is false to affirm that Iron oxide is used to produce toothpastes and antacids, and that calcium carbonate is used to produce dark pigment in makeup. This chart can be corrected by swapping the uses for iron oxide and calcium carbonate. For its black color, iron oxide is often used to produce dark pigments, while calcium carbonate is used in antacids and its abrasive properties are used in toothpastes.
