Science chapter 12 lesson 2

What are the four main categories of chemical reactions

• synthesis

• decomposition

• replacement reactions (single and double- replacements)

• combustion

two or more reactants react and form a product

• synthesis

• decomposition

• combstion

• single replacement

• double replacement

one reactant breaks down and two or more products form

• synthesis

• decomposition

• combstion

• single replacement

• double replacement

a reaction in which parts of two substances switch places and make two new substances

• synthesis

• decomposition

• combstion

• single replacement

• double replacement

one element replaces another element in a compound

• synthesis

• decomposition

• combstion

• single replacement

• double replacement

a substance combines with oxygen and releases energy

• synthesis

• decomposition

• combustion

• single replacement

• double replacement

at least two reactants; one product

• synthesis

• decomposition

• replacement

• combustion

one substance combines with oxygen and releases energy (thermal and light)

• synthesis

• decomposition

• replacement

• combustion

one reactant; at least two products

• synthesis

• decomposition

• replacement

• combustion

a reactant(s) breaks apart, and compound rearrange and for a new product(s)

• synthesis

• decomposition

• replacement

• combustion
