Match the following terms with their definitions. Write ONLY the NUMBER that is in the column on the left of the definitions in the answer field next to each term.  (There are more definitions than needed.)   Terms:  a) electronegativity – [7] b) lattice energy- [10] c) pressure – [5] d) sigma bond- [2] Definitions:      1 model that describes the changes in the atomic orbitals of an atom when it forms a covalent compound 2 covalent bond formed by overlap of atomic orbitals along the internuclear axis 3 volume of 1 mole of gas at STP, approximately 22.4 L for gases behaving ideally 4 covalent bond in which electrons are not shared equally 5 force exerted per unit area 6 covalent bond formed by side-by-side overlap of atomic orbitals 7 tendency of an atom to attract electrons in a bond to itself 8 hypothetical gas whose physical properties are perfectly described by the gas laws 9 covalent bond in which electrons are shared equally or almost equally 10 energy required to separate one mole of an ionic solid into its component gaseous ions  

    Bonus (5 pts) Chlorine dioxide gas (ClO2) is used as a commercial bleaching agent. It bleaches materials by oxidizing them. In the course of these reactions, the ClO2 is itself reduced.      One method of preparing ClO2 is by the reaction of chlorine and sodium chlorite:             Cl2(g) + 2 NaClO2(s) → 2 ClO2(g) + 2 NaCl(s)If you allow 15.5 g of NaClO2 to react with 2.00 L of chlorine gas at a pressure of 1.50 atm at 21 oC, how many grams of ClO2 can be prepared?

A sample of nitrogen gas has a volume of 16.0 mL at a pressure of 78.0 torr.  Determine the pressure of this gas at a volume of 25.0 mL.  (You may show work for possible partial credit.)
