Types of Chemical Reactions
Synthesis Reaction
Two or more substances react to produce a single product
Two compounds can also combine to form one compound
A compound and an element can combine to form one compound
Combustion Reaction
Oxygen combines with a substance and releases energy in the form of heat and light
Metal + Oxygen → Metal Oxide
Nonmetal + Oxygen → Nonmetal Oxide
Compound + Oxygen → 2 or more oxides
Not all combustion reactions are synthesis reaction.
Decomposition Reaction
A single compound breaks down into two or more elements or new compounds
It is the opposite of a synthesis reaction
Decomposition reactions often require an energy source (heat, light, electricity)
1 compound → element + element
1 compound → compound + compound
Replacement Reactions
Double Replacement Reaction
Occurs when ions exchange between compounds
All double replacement reactions produce either water, a precipitate (the solid product during a chemical reaction in a solution), or a gas
One compound is a solid, water, or gas, and the other is an aqueous solution
Single Replacement Reaction
Atoms of one element replace the atoms of another element in a compound
Action of Water on Alkali Metals - Metal Replaces Hydrogen
Action of Water on Alkaline Earth Metals - Metal Replaces Hydrogen
Action of Elemental Metals on Combined Metals - Metal Replaces Another Metal
Action of Elemental Halogens on Combined Halogens - Nonmetal Replaces Nonmetal
