(3 point) Suppose a sample of water is contaminated by a nonvolatile contaminant such as lead. Why doesn't boiling eliminate the contaminant? (5 points) Looking at the diagram page 432 on 433, please provide alternative examples of each type of solid (molecular solid, ionic solid, covalent atomic solids, nonbonding atomic solids, and metallic atomic solids) for which a physical example or photo could be added to a poster. Atomic solids Covalent Nonbonding Metallic Held together by covalent bonds Held together...
