North Carolina Essential Standards and Clarifying Objectives:

Chm. 1.2 Understand the bonding that occurs in simple compounds in terms of bond type, strength, and properties.

            1.2.4 Interpret the name and formula of compounds using IUPAC convention.

         Write binary compounds of two nonmetals: use Greek prefixes (di-, tri-, tetra-, ...)

         Write binary compounds of metal/nonmetal*

         Write ternary compounds (polyatomic ions)*

         Write, with charges, these polyatomic ions: nitrate, sulfate, carbonate, acetate, and ammonium.

         Know names and formulas for these common laboratory acids: HCl, HNO3, H2SO4, HC2H3O2 (CH3COOH)

*The Stock system is the correct IUPAC convention for inorganic nomenclature.

 

Chm. 2.2 Analyze chemical reactions in terms of quantities, product formation, and energy.

            2.2.5 Analyze quantitatively the composition of a substance.

         Calculate empirical formula from mass or percent using experimental data.

         Calculate molecular formula from empirical formula using molecular weight.

         Determine percentage composition by mass of a given compound.

         Perform calculations based on percent composition.

         Determine the composition of hydrates using experimental data.
