Sodium metal reacts violently with water and chlorine is a toxic gas, yet we eat sodium chloride. Why is this possible? Select one: a. The properties of compounds are different from the properties of the elements that form the compounds.
b. The properties of compounds are identical to the properties of the elements that form the compounds, and we should not eat sodium chloride because it is toxic.
c. The physical properties of compounds are different from the physical properties of the elements that form the compounds, but the chemical properties of the elements and compound are the same.
d. The chemical properties of compounds are different from the chemical properties of the elements that form the compounds, but the physical properties of the elements and compound are the same.
