CHEM 16FIRST LONG EXAM REVIEW
I. CHEMICAL NOMENCLATURE
A. Name the following compounds1. BH32. Pb(HSO4)23. HBrO34. LiOH5. Cu(NO3)2B. Write the chemical formula6. Hydrocyanic acid7. Phosphorus pentachloride8. Potassium Permanganate9. Stannous acetate10. Calcium phosphate
II. SOLUBILITY RULES. Tell whether the compound is soluble or insoluble
1. AgNO32. PbCl23. BaSO44. (NH4)2S5. MgCO36. Na3PO47. Be(OH)28. Cu3PO4
III. ELECTROLYTES / NONELECTROLYTES. Identify if the given solution is strong, weak, or nonelectrolyte
1. Mineral water2. Sucrose3. Lead (II) acetate4. Potassium phosphate5. Sulfurous acid
6. Sulfuric acid7. Calcium hydroxide8. Ammonia9. Energy drink10. Deionized waterIV. MODIFIED TRUE OR FALSE. Write T if the statement is TRUE. If it is FALSE, replace the underlined word(s) with the word(s) that will make the statement correct.1. The electron configuration of Br- (Atomic no= 35) is 1s22s22p63s23p63d104s24p62. The color of the flame emitted by barium ion is yellow green.3. For phosphorus pentachloride, its electron group geometry is octahedral and its molecular geometry is square planar4. Heating the crude benzoic acid + water mixture decreases the solubility of the sample5. In gravity filtration, the flow rate is maximized by using fluted filter paper6. Purification by sublimation obtains a product of high purity and high %recovery
V. PROBLEM SOLVING1. Balance the following chemical reactions:a. AgNO3 + K3PO4 Ag3PO4 + KNO3b. B2Br6 + HNO3 B(NO3)3 + HBr
2. Write the electron configuration of W (Atomic number = 74) and identify its quantum numbers
3. WRITING IONIC EQUATIONa. Iron (III) nitrate + Sodium hydroxideChemical Equation:Type of Chemical Reaction:Balanced Chemical Equation:Total Ionic Equation:Net Ionic Equation:b. Calcium iodide + chlorine gasChemical Equation:Type of Chemical Reaction:Balanced Chemical Equation:Total Ionic Equation:Net Ionic Equation:c.
