1. Synthesis: two elements combining into a compound
2. Decomposition: a compound being separated into elements
3. Single Replacement: metal/H switches with metal/H or halogen switches with halogen
4. Double Replacement: the cations swap anions; sometimes a precipitate is formed.
5. Combustion: CxHy + O2 -> CO2 + H2O + Heat.
Basically, heat is always a product.
(Sorry, Mr. Olson, I plagiarized your reactions worksheet).
Speaking of combustion, the idea of spontaneous combustion fascinates me. Apparently, Robert Francis Bailey was a homeless man who suddenly - well, spontaneously combusted. And thus, he died in the flames.
So I guess the spontaneous reaction combustion that affected poor Mr. Bailey was an exothermic reaction. x___X
Other reactions include oxidation and reduction reactions. In oxidation, electrons are stolen by the electron-hungry Oxygen. In a reduction reaction, electrons are gained. Any reaction where electrons are transferred is called a redox reaction.
