CH110 FA10 SAS 2 By the end of Today’s Lecture you should know: Reaction stiochiometry and balanced equations Combustion Decomposition Combination Precipitation and Neutralization reactions Net ionic equations and spectator ions KEY QUESTIONS: THE BIG PICTURE Chemical Reactions: Introduction How do you determine the outcome of a chemical reaction? How do we balance chemical reactions? What types of reactions have we already encountered? Remember: Chemistry deals with matter and its changes What forces drive reactions to occur spontaneously? How can identifying spectator ions and writing net ionic equations help us predict reaction chemistry?
