9. What is a binary molecular compound? A compound containing only two different types of atoms that are COVALENTLY bonded N 2 O

10. Practice CCl 4 As 2 O 3 Br 2 H 2 O 2 NF 3 Carbon tetrachloride Diarsenic trioxide Bromine Dihydrogen dioxide Nitrogen Trifluoride

11. COMMON NAMES H 2 O H 2 O 2 NH 3 N 2 H 4 N 2 O NO water hydrogen peroxide ammonia hydrazine nitrous Oxide nitric Oxide dihydrogen monoxide dihydrogen dioxide nitrogen trihydride dinitrogen tetrahydride dinitrogen monoxide nitrogen monoxide

12. Using the rules for naming binary molecular compounds, describe how you would name N 2 O 4. 1. Element on the left does it need a prefix. If yes assign it. 2. Identify second element and change ending to ide. 3. Assign prefix to second element. Yes 2=di Dinitrogen O-oxygen = oxide 4=tetra Tetroxide Dinitrogen tetroxide

13. Acids

14. ACIDSOxyacids Binary Acids Hydro + element-ic + acid HCl Hydrochloric Acid OxyANION root – ic + Acid H 2 SO 4 Sulfuric Acid

15. What is the difference between a binary acid and an oxyacid? Binary acids contain hydrogen and one other element, they are named with the prefix hydro- and the root of the other element with the suffix –ic acid Oxyacids contain oxygen bonded to another non-metal element, they are named based off the OXYANION that they are formed from.
