7. Each of the following statements about the properties of matter are false. Choose two statements and explain the fallacy. a. Aluminum conducts electricity because it allows electrons to flow between covalent bonds between atoms in the crystal lattice. b. The bonding within H,O molecules explains why water has a high boiling point. The geometry of an ionic compound determines if it's polar or non-polar. с.
