1. Chemistry I Unit IV Objectives Chapter 10
I.   What is a mole? Define and describe its importance.
II.  Memorize and use Avogadro’s number to calculate the number of particles from moles or the number of moles from particles. 
III.  Define and be able to calculate molar mass of an element and formula mass of a compound (gram atomic/formula mass). Use this to calculate moles from mass or mass from moles.
IV.    Use molar volume (22.4 dm3) to calculate the number of moles in a gas sample at standard conditions of temperature (0C / 273 K) and pressure (1 atm / 760 Torr / kpa).

2. Objectives Unit IV Chapter 10 cont..
V.   Use the mole diagram to convert from and to mass, volume, particles or moles of an element or compound given any one of those properties. 
VI.  Calculate % composition of a given formula.
VII.  Use percent composition to determine the empirical formula of an unknown substance.
VIII.  Be able to use the empirical formula and molar mass to calculate the molecular formula of a given compound.

3. Chemistry I Unit IV Objectives Ch.11
I.  What is a chemical reaction? Describe the characteristics of chemical reactions.
II.  Be able to write and balance chemical equations, including word and formula equations.
III. Identify the reactant and products in chemical equations and use correct chemical notation to show the physical state. (s) (l) (g) (aq)
IV. Recognize and identify the characteristics of the six types of chemical reactions:
a. Direct Combination (Synthesis) ex.      A + B  AB
b.  Decomposition (Analysis) ex.      AB  A + B
c.   Single Replacement
1.   Cation (metal) replacement ex.   A + BX  AX + B

4. Chemistry I Unit IV Objectives Chapter 12
I.      What is stoichiometry? Define and describe its importance.
II.     Relate stoichiometry to the coefficients in
balanced chemical equations and conservation
of mass.
III.   Be able to solve the following types of
stoichiometry problems.
a. Mass – Mass
b. Volume – Volume
c.  Particle – Particle
d. Any combination of mass, volume & particles

5. Objectives Unit IV Chapter 12 cont…
IV.     Determine the limiting reactant in a chemical
reaction and the reactant in excess. Explain how
the limiting reactant controls the amount of
product(s).
V.   Use the limiting reactant concept to determine the
amount(s) of product(s) (theoretical yield) if
reactants are not present in stoichiometric
proportion
VI.  Calculate theoretical yield and use the actual yield
to find the percent (%) yield.
