Name Anna Stevens Objectives: CHM 092: EXPERIMENT 10 TYPES OF CHEMICAL REACTIONS & BALANCING EQUATIONS To recognize when a chemical reaction has occurred. To learn about the different types of chemical reactions. To write and balance chemical equations. Recognizing a Chemical Reaction: Look for evidence of a chemical reaction, such as: Temperature change (heat or cold) Light Formation of precipitates (solids) Color changes Gas evolution (formation of bubbles) Five Types of Chemical Reactions: Combination reactions: Decomposition reactions: Two combine into one. A + BAB One decomposes into two. CDC + D One replaces another. CHM 092 10-1 PROCEDURE: I. Combination or Synthesis Reactions A + BC AC + B Single replacement: Double displacement: Switch partners. Combustion reactions (complete oxidation): Hydrocarbon burns in the presence of oxygen, CxHy+O2 > CO2+H2O producing carbon dioxide and water. AB+CD CB + AD 1.
