(A) bonding pair (D) homogeneous mixture 1. Two or more different elements chemically combined make a(n) (C) compound (E) heterogeneous mixture (B) isotope 2. The formula of a compound (A) must be electrically neutral (B) is written as a combination of elemental symbols (C) may contain subscripts specifying the number of each kind of atom (D) reveals whether the compound is ionic or covalent (E) all of these 3. A reaction in which a fuel burns in the presence of oxygen to form carbon dioxide and water vapor is the specific type of reaction called a (A) redox reaction. (B) combustion (C) acid-base (D) single replacement (E) precipitation 4. A certain covalent molecule, of general formula AT,, follows the Octet Rule. What can we reasonably conclude about its geometry? (A) the geometry is bent with a bond angle of either 120°or 180° (B) the molecule must be tetrahedral since there is only one possibility for this formula (C) the geometry is octahedral if the central atom A has one lone pair
