Writing Empirical Formulas and Naming Ionic Compounds, Acids, and Hydrates Using the "criss-cross" method, write valid empirical formulas for the compounds that would be formed by combining the given atoms and polyatomic ions. Then name the compound. If a chemical formula is provided, name that chemical compound. For example, sodium with chlorine: Na & CI NaCl Sodium chloride 1. Combine a. b. C. 23 m. p. n. 0. 1. V. aa. ab. ac. ad. ae. af. ah. al. ak. III Activity 2: PAC organic Nomenclature am. 25 Activity 2: IUPAC Inorganic Nomenclature 2. Provide the correct chemical formula for the following IUPAC names a. Acetic acid: b. Boron trihydride: c. Hydroiodic acid: d. Carbon tetrachloride: e. Iodine heptafluoride: f. Phosphorus pentabromide: 9. Tetraphosphorus decasulfide: h. Calcium sulfate dihydrate: i. Cobalt(II) chloride hexahydrate: J. Barium peroxide octahydrate: k.
