I can:

1)      Distinguish between the terms chemical formula, empirical formula, molecular formula, and structural formula.

2)      Identify ions (monatomic ions and polyatomic ions)

3)      Name ions in the traditional (-ic, -ous) and Stock system (II, III)

4)      Define the terms cations and anions

5)      Write and name ionic compounds

6)      Write and name nonmetal (molecular) compounds (mono-, di-, tri-, etc.)

7)      Know definition of mole and Avogadro’s Number (6.02 x 10²³ molecules in one mole)

8)      Calculate the molar mass of a substance

9)      Convert from moles to mass(g), molecules, volume(L) using conversion factor.

10)  Calculate % composition

11)  Calculate empirical and molecular formulas from mass percent

12)  Define hydrated compounds

13)  Determine the formula of a hydrated compound from experimental data

14)  State that Antoine Lavoisier introduced the law of conservation of matter.

15)  Identify products and reactants in a chemical equation

16)  Write combustion equations

17)  Balance equations and understand that subscripts in the formulas of reactants and products cannot be changed to balance equations.

18)  Find the molecular and empirical formulas and differentiate between the two

19)  Use the stoichiometric factor (© of the problem) (i.e. 1 mol CO₂ = 1 mol C)

20)  Define limiting reactant and excess reactant

21)  Determine the limiting reactant and excess reactant

22)  Solve problems involving Limiting Reactants

23)  Given the actual yield, know how to find the theoretical yield and the percent yield.
