Type of Reaction
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
(1)CS2+(3)O2-->(1)CO2+(2)SO2
_CO2+_H2O-->_C2H5OH+_O2
(2)CO2+(3)H2O-->(1)C2H5OH+(3)O2
This reaction, which is also commonly known to mean build, builds elements into compounds.
A+B=AB
What is synthesis?
_CH2O+_H2-->_CH3OH
(1)CH2O+(1)H2-->(1)CH3OH
Already Balanced!
_F2+_H2O-->_OF2+_HF
(2)F2+(1)H2O-->(1)OF2+(2)HF
_C2H2+_O2-->_CO2+_H2O
(2)C2H2+(5)O2-->(4)CO2+(2)H2O
This type of reaction switches two elements in two different compounds.
AB+XY-->AY+XB
What is double replacement reaction?
_HCl-->_H2+_Cl2
(2)HCl-->(1)H2+(1)Cl2
_CH4+_O2-->_CO2+_H2O
(1)CH4+(2)O2-->(1)CO2+(2)H2O
_CO2+_H2O-->_C2H6+_O2
(4)CO2+(6)H2O-->(2)C2H6+(7)O2
This type of reaction breaks down a compound into elements.
AB-->A+B
What is decompostion?
_C2H2+_H2-->_C2H6
(1)C2H2+(2)H2-->(1)C2H2
_SO2+_H2-->_S+_H2O
(1)SO2+(2)H2-->(1)S+(2)H2O
_NH3+_NO-->_N2+_H2O
(4)NH3+(6)NO-->(5)N2+(6)H2O
