  3. Answers • B • D • D • B • C • B • D • C • A • B

  4. Types of Naming • Ionic – metal + nontmetal (no prefixes) • Covalent – nonmetal + nonmetal (prefixes) • Acid – begins with H – use acid naming rules • Base – end in OH – use ionic naming rules

  5. Write the names and types of • N4O5 • HCH3COO • Mg(OH)2 • H2SO3 • FeS • CuSO4 • CO • Tetranitrogenpentoxide – C • Acetic acid – A,I • Magnessium Hydroxide – B,I • Sulfurous acid – A,I • Iron (II) Sulfide - I • Copper (II) Sulfate - I • Carbon monoxide - C

  6. Write the balance formula for: • Nitric acid • Hydrosulfuric acid • Calcium hydroxide • Tricarbonoctasulfide • Cobalt (III) Oxide • HNO3 • H2S • Ca(OH)2 • C3S8 • Co2O3

  7. Questions • WTDB ionic and covalent bonds? • WTDB polar and nonpolar? • Are more compound polar or nonpolar? • How does VSEPR determine shape? • If something starts with an H what type of compound is it? • Can you technically call an ionic compound a molecule?

  8. Which bond has a stronger electronegativity with H A) Cl B) F C) N • What are the three types of covalent bonds? • How many atoms and electrons are shared in a single covalent bond? Double? Triple? • If a compound has a polyatomic is it covalent or ionic? • What 3 things does the Law of Definite Proportion say about a compound? • What does the Law of Multiple Proportions say about two elements?

  9. 13. What is a hydrogen bond? Why can only hydrogen make this bond? 14. What is the shape of a water molecule? 15. How many bonds can C, H, N, O, F make? 16. What are the 7 diatomic elements? 17. Which of the diatomic elements are bonded with single bonds? 18. Double? 19. Triple? 20. Why do atoms bond?
