5.01 Evaluate various types of chemical reactions 5.02 Evaluate the law of conservation of matter to the balancing of chemical equations.  ·  Write and balance ionic equations.  ·  Write and balance net ionic equations for double replacement reactions.  ·  Recognize that hydrocarbons (C,H molecule) and other molecules containing C, H, and O burn completely in oxygen to produce CO2 and water vapor.  ·  Use reference table rules to predict products for all types of reactions to show the conservation of mass.  ·  Use activity series to predict whether a single replacement reaction will take place.  ·  Use the solubility rules to determine the precipitate in a double replacement reaction if a reaction occurs.  ·  Write and balance chemical equations.  ·  Write net ionic reactions.  ·  Predict and write formulas using the reference tables.
 * Analyze reactions by types: single replacement, double replacement (including acid-base neutralization), decomposition, synthesis, and combustion of simple hydrocarbons.
 * Predict products.
 * Write and balance formulas and equations
 * Write net ionic equations**.**
 * Students should be able to: **
 * Identify a reaction by type.
 * Predict product(s) in a reaction using the reference tables.
 * Identify acid-base neutralization as double replacement.
 * Students should be able to: **
 * Students should be able to determine if a chemical reaction has occurred based on the following criteria: **
 * Precipitate Tie to solubility rules (Goals 2.04 and 5.01).
 * Product testing - Know the tests for some common products such as oxygen, water, hydrogen and carbon dioxide. (tests to know: burning splint for Oxygen, Hydrogen and Carbon Dioxide (include knowledge of safety precautions) lime water for Carbon Dioxide).
 * Color Change – Distinguish between color change as a result of chemical reaction, and a change in color intensity as a result of dilution.
 * Temperature change – Tie to endothermic/exothermic reaction. Express  D H as (+) for endothermic and (–) for exothermic.
