Name ____________________________________________ Regents Review #2 Periodic Table, Bonding, Reactions, and Moles 1. Explain, in terms of subatomic particles, why the radius of a chloride ion is larger than the radius of a chlorine atom. Base your answers to questions 2 through 6 on the information below. The ionic radii of some Group 2 elements are given in the table below. 2. On the grid on your answer sheet, mark an appropriate scale on the axis labeled “Ionic Radius (pm).” 3. On the same grid, plot the data from the data table. Circle and connect the points. 4. Estimate the ionic radius of strontium. 5. State the trend in ionic radius as the elements in Group 2 are considered in order of increasing atomic number. 6. Explain, in terms of electrons, why the ionic radius of a Group 2 element is smaller than its atomic radius. 7. What is the total number of electron pairs shared between the carbon atom and one of the oxygen atoms in a carbon dioxide molecule? 8. Explain, in terms of valence electrons, why the bonding in magnesium oxide, MgO, is similar to the bonding in barium chloride, BaCl2. 9. Identify the type of bonding between the atoms in an oxygen molecule. Base your answers to questions 10 through 12 on the information below. In 1864, the Solvay process was developed to make soda ash. One step in the process is represented by the balanced equation below. 10. Write the chemical formula for one compound in the equation that contains both ionic bonds and covalent bonds. 11. Explain, in terms of electronegativity difference, why the bond between hydrogen and oxygen in a water molecule is more polar than the bond between hydrogen and nitrogen in an ammonia molecule. 12. Draw a Lewis electron-dot diagram for the reactant containing nitrogen in the equation. Base your answer to question 13 on the diagram below. 13. Identify the two types of bonds in the compound sodium stearate. Base your answers to questions 14 through 16 on the information below. The Solvay process is a multistep industrial process used to produce washing soda, Na2CO3 (s). In the last step of the Solvay process, NaHCO3 (s) is heated to 300˚C, producing washing soda, water, and carbon dioxide. The reaction is represented by the balanced equation below. 14. Write the IUPAC name for washing soda. 15. Identify the type of chemical reaction represented by the equation. 16. Determine the total mass of washing soda produced if 3,360 kilograms of NaHCO 3 reacts completely to produce 360 kilograms of H2O and 880 kilograms of CO2. Base your answer to question 17 on the information below. Ozone, O3 (g), is produced from oxygen, O2 (g), by electrical discharge during thunderstorms. The unbalanced equation below represents the reaction that forms ozone. 17. Balance the equation for the production of ozone, using the smallest whole-number coefficients. Base your answers to questions 18 through 21 on the information below. The reaction between aluminum and an aqueous solution of copper (II) sulfate is represented by the unbalanced equation below. 18. Identify the type of chemical reaction represented by the equation. 19. Balance the equation using the smallest whole-number coefficients. 20. Explain why the equation represents a chemical change. 21. Determine the total mass of Cu produced when 1.08 grams of Al reacts completely with 9.58 grams of CuSO4 to produce 6.85 grams of Al2(SO4)3. 22. Calculate the gram formula mass of glycine, NH2CH2COOH. Your response must include both a numerical setup and the calculated result. [2] 23. Show a numerical setup for calculating the percent composition by mass of water in KAl(SO4)2•12 H2O.
