Types of Chemical Reactions
AB --> A + B
What is the general form of a decomposition reaction?
AB + CD --> AD + CB
What is the general form of a double displacement reaction?
A + BC --> AC + B
What is the general form of a single displacement reaction?
A + B --> AB
What is the general form of a synthesis reaction?
This is a single displacement reaction.
What kind of reaciton is this? Mg + 2H2O --> Mg(OH)2 + H2
This is a decomposition reaction.
What kind of reaction is this? 2H2O --> 2H2 + O2
This is a synthesis reaction.
What kind of reaction is this? 8Fe + S8 --> 8FeS
This is a combustion reaction.
What kind of reaction is this? C10H8 + 12O2 --> 10CO2 + 4H2O
This is a double displacement reaction.
What kind of reaction is this? Pb(NO3)2 + 2KI --> PbI2 + 2KNO3
A combustion reaction occurs when oxygen combines with another compound to form water and carbon dioxide. These reaction are exothermic, meaning they produce heat.
Describe a combustion reaction.
A decomposition reaction occurs when a complex molecule breaks down to its elements or simpler compounds.
Describe a decomposition reaction.
A double displacement reaction occurs when the anions and cations of two different molecules switch places, forming two entirely different compounds.
Describe a double displacement reaction.
A single displacement reaction occurs when one more reactive element trades places with another element in a compound.
Describe a single displacement reaction.
A synthesis reaction occurs when two or more elements or simple compounds combine to form a more complicated substance.
Describe a synthesis reaction.
A substance that forms in a chemical reaction
Product
A substance or molecule that participates in a chemical reaction
