Unit 5: Chemical Reactions and the Mole  November 4 - December 11
Chemical reactions affect you every second of every day.  For example, life-sustaining chemical reactions occur continuously in
your body every time you take a breath you are supply a reactant and eliminating a waste product.  Do you know which one is oxygen
and which one is carbon dioxide? Moles are the means by which matter is grouped to make conversions to mass and numbers of
particles.  Thank you moles!  Stoichiometry is used to identify the quantitative relationships in a balanced chemical equation and
mole ratios!

Chapter 10 - Chemical Reactions
Recognize evidence of chemical change, then represent the chemical reaction
with equations.  There are several types of reactions that you will classify and identify:
synthesis, combustion, decomposition, replacement(substitution), precipitation,
water formation or gas formation.
When writing chemical reactions equations are balanced in terms of moles

Chapter 11 - The Mole
Moles are used to count particles:
1 mole  = 6.02 x 10^23 representative particles; Avogadro's number
Molar particles can be atoms of compounds or hydrates
Lots of fun puzzling conversions are performed when learn moles.

Chapter 12 - Stoichiometry
One of the key concepts in chemistry - conservation of mass
Write mole rations from balanced chemical reactions.  Identify the limiting reactant
in a chemical reaction and determine the percent yield (how products are referred)
Students know how to calculate the masses of reactants and products in a chemical reaction from the mass of one of the
reactants or products and the relevant atomic masses.

Six Differences between nuclear reactions and chemical reactions.
Nuclear Reactions                                                                 Chemical Reactions
1.  Protons and neutrons react inside nucleus.                         1.  Electrons react outside nucleus.
2.  Elements transmute into other elements.                        2.  The same number of each kind of atom appear in the reactants and
products.
3.  Isotopes react differently.                                              3.  Isotopes react the same.
4.  Independent of chemical  combination.                             4.  Depend on chemical combination.
5.  Energy changes equal 10^8 kJ.                                          5.  Energy changes equal 10 - 10^3 kJ/mol.
6.  Mass changes are detectable.                                           6.  Mass reactants = mass products.
