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.
