Question

why is it important to know the physical properties of compounds in a lab setting? to predict the chemical reactions of the compound to determine the molecular structure of compounds to calculate the atomic number of elements in the compound to identify possible uses of the compound and handle spills properly

Explanation:

Physical properties like melting - point, solubility etc. help in understanding how a compound can be used and how to handle it safely in case of spills. Predicting chemical reactions relates more to chemical properties, determining molecular structure is through techniques like spectroscopy, and calculating atomic number is not related to physical properties.

Answer:

To identify possible uses of the compound and handle spills properly
