Unit 4 Study Guide Nomenclature Name: Date: Per: Directions: Complete the questions below in preparation for the exam. I will not go over the study guide in class, but I am available after school for individual questions. The test format is multiple choice, and short answer. Calculations will be included in both sections. Things you will be given on the exam: a periodic table (it will NOT have the oxidation numbers listed) a common ion sheet Things you need to know: how to tell the number of atoms of each element in a chemical formula the charges numbers for elements on the periodic table (besides transition metals) the prefixes to use with covalent compounds how to write names and formulas for o ionic compounds o covalent compounds o acids Helpful Hints: Write the formula or the name first in the margin, then compare it back to the answer choices to find the correct answer Take your time!!! You have the whole class period- there is no need to rush. If you don’t understand directions or a question, ask! I will be happy to clarify or restate the question. Remember the catch phrase… o for naming acids: “if you ate something icky, you need to bite something delicious” 1. Classify each of the following compounds as acidic, ionic, or covalent. Then write the formula for each. Chemical Name Acidic, Ionic, or Chemical Formula Molar Mass of Moles present in Molecular. If Compound 100 grams Molecular, state if it is transition or nontransition Manganese (IV) Cyanide Sodium Nitrate Lead (IV) Selenide Magnesium Hydroxide Magnesium Oxide Cobalt (II) Selenide Copper (III) Phosphate Hydrosulfuric Acid Ammonium Sulfate Phosphorous Acid 2. Classify each of the following compounds as acidic, ionic, or covalent. Then write the name for each. Show your work for the first THREE molar masses and calculations for grams present in five moles of compound in the space provided below the table. Chemical Formula Acidic, Ionic, or Chemical Name Molar Mass of Grams present in Molecular. If Ionic Compound 5 moles of state if it is transition compound or non-transition Li3N Fe2(SO4)3 H2SO4 PbCl2 SnS2 H2SO3 CO2 Cu3P N2O3 HCl Li3N Fe2(SO4)3 3. What does it mean for a compound to be “binary?” 4. What is a cation? 5. What is an anion? 6. What is a polyatomic ion? H2SO4 7. How do you determine the charge of an ion or polyatomic ion? 8. Which elements on the periodic table are normal, non-transition metals? (you do not need to list them all, just make a statement about how/where to find them). 9. Which elements on the periodic table are transition metals? (you do not need to list them all, just make a statement about how/where to find them). 10. When given the name of an acid, how can you tell if it is… A. Binary? B. an oxyacid that contains a polyatomic ion ending in ate? C. an oxyacid that contains a polyatomic ion ending in ite?
