This type of reaction replaces one type of atom with another that is in a compound.
XY+A-->AY+X
What is single replacement reaction?
_H2+_O2-->_H2O
(2)H2+(1)O2-->(2)H2O
_C2H6+_Cl2-->_C2H5Cl+_HCl
(1)C2H6+(1)Cl2-->(1)C2H5Cl+(1)HCl
_NO2+_H2O-->_NH3+_O2
(4)NO2+(6)H2O-->(4)NH3+(7)O2
This reaction always requires oxygen and releases carbon dioxide and water.
X+O2--> CO2+H2O
What is combustion?
(1)PCl5-->(1)PCl3+(1)Cl2
Already Balanced!
_CS2+_O2-->_CO2+_SO2

_CO2+_H2O-->_C2H6+_O2
(4)CO2+(6)H2O-->(2)C2H6+(7)O2
This type of reaction breaks down a compound into elements.
