Chapter 19 - Section 2 and 3
Endothermic reaction
*energy in the form of heat is required* for a chemical reaction to take place
Double Displacement
AB + CD → AD + CB
Decomposition Reaction
ABC → AB + C AB → A + B
Exergonic reaction
a chemical reaction in which energy is released in the form of heat (Hint: exit) For example wood burning or exploding dynamite
Endergonic Reaction
a reaction that requires more energy to break bonds than is released when new ones form For Example: cold pack
Synthesis Reaction
A + B = AB
Single Displacement Reaction
A + BC → AC + B
Type - Synthesis Reaction
Types of Reactions A + B → AB
Type - Single - Displacement Reaction
Types of Reactions A + BC → AC + B
Type - Double displacement Reaction
Types of Reactions AB + CD → AD + CB
Type - Decomposition Reaction
Types of Reactions AB → A + B
Type - combustion reaction
Types of Reactions example burning
Single Displacement Reaction
When one element replaces another element in a compound
Combustion reaction
an example is a firecracker exploding
Decomposition Reaction
an example is an electric current passing though water and reducing it to hydrogen and oxygen
Synthesis Reaction
an example is rust forming on an iron gate
precipitate
insoluble solid forms as a result of double displacement reaction is called:
Exothermic reaction
when *energy is released* in the primary form of heat
