CuCrO4 CuCrO4 Representation 1 Representation 2 000 Shown here are the melting points of four different ionic compounds. Substance Melting Point (°C) NaCl 801 MgO 2,852 Nal 661 NaBr 747 Recall that a particulate representation of NaCl is: NaCl This model could be improved by showing the difference in sizes of the ions in NaCl. NaCl
1. Consider the following statement:
The chemist pours grains of solid NaCl into the gap between the wires. Based on the particulate representations attached in the 1st image, predict if the light bulb will glow with the addition of grains of solid sodium chloride to the container. Include reasoning that supports your prediction.
2. Shown in the second image are the melting points of four different ionic compounds and the particulate representation of NaCl. Draw particulate representations of MgO, NaI, and NaBr. Be sure to represent both the charges of the ions and their sizes in your drawings.
3. Use the particulate representations you have drawn and Coulomb's law to explain the trends in boiling point shown in the table.
