Question

1.) Draw the Lewis structure of ozone (O3). How many single covalent

bonds and double covalent bonds are present in its structure? 2.) True or False. A bond between a chlorine atom (electronegativity = 3.0) and a fluorine atom (electronegativity = 4.0) will be a polar covalent bond. 3.) Determine whether each of the following molecules is polar or nonpolar: a.) b.) (hint: the C-Cl bond is polar; the C-H bond is nonpolar). c.) 4.) Which of the following is not evidence of a chemical reaction? (a.) a color change (b.) a temperature decrease (c.) a new smell (d.) a change in appearance only 5.) Write the chemical equation that matches the following description of a reaction. A solution of sodium hydroxide reacts with gaseous carbon dioxide to produce liquid water and a solution of sodium carbonate. 6.) True or False. The following equation is balanced. NaHCO3 (aq) + HBr (aq) → NaBr (aq) + H2O (l) + CO2 (g)
