Classify each as an Acid, Molecular, Binary Ionic, or Ternary Ionic Compound: CuSO4 5. V2S3 CS2 6. (NH4)3PO4 Fe(OH)3 7. HF CaO 8. P4Se3 Copyright © Pearson Education, Inc., or its affiliates. All Rights Reserved.

Practicing Skills: Chemical Names and Formulas Naming Chemical Compounds Does it start with H? If it does it is an acid. Does it have a polyatomic ion? All polyatomic ions end in –ite or –ate except for Ammonium, Hydroxide, and Cyanide Is it covalent or ionic? If it is covalent, use prefixes & -ide. Can there be more than one cation (transition elements,Sn, or Pb)? If yes, use roman numerals to specify cation charge. Copyright © Pearson Education, Inc., or its affiliates. All Rights Reserved.

Classify each as an Acid, Molecular, Binary Ionic, or Ternary Ionic Compound: Bromine Pentachloride 5. Strontium Chloride Lithium Ethanoate 6. Sulfur Dioxide Zinc Phosphide 7. Aluminum Hydroxide Hydrochloric Acid 8. Cobalt (III) Carbonate Copyright © Pearson Education, Inc., or its affiliates. All Rights Reserved.

Practicing Skills: Chemical Names and Formulas Writing Chemical Formulas From Names Are there prefixes? If yes, use them to determine subscripts. Is it an acid? Binary or ternary? Does it end in something other than –ide? If yes, then polyatomic. Use table 9.3 Are there Roman Numerals? If yes, use to specify cation charge.
