What type of rxn?
Double
Replacement
Decomposition CombustionSynthesis Single
Replacement
•Products are
CO2 + H2O
•Make new cmpds
•Flip and drop + / -
•Make new cmpd
•Flip and Drop + / -
•Check if new element
is diatomic
•Split into elements
•Check for diatomics
•Find Charges
•Flip and Drop
Ex 1) Mg + O2 →

What type of rxn?
Synthesis
•Find Charges
•Flip and Drop
Ex 1) Mg + O2 →
What type of rxn?
Synthesis
•Find Charges
•Flip and Drop
Ex 1) Mg + O2 →
Mg2+ O2-
What type of rxn?
Synthesis
•Find Charges
•Flip and Drop
Ex 1) Mg + O2 →
Mg2+ O2-
Mg2O2 = MgO
What type of rxn?
Synthesis
•Find Charges
•Flip and Drop
Ex 1) Mg + O2 → MgO
Ex 2) H2O →

What type of rxn?
Decomposition
•Split into elements
•Check for diatomics
Ex 2) H2O →
H + O (both are diatomic)
What type of rxn?
Decomposition
•Split into elements
•Check for diatomics
Ex 2) H2O → H2 + O2
What type of rxn?
Decomposition
•Split into elements
•Check for diatomics
Ex 3) Cu (II) + AgNO3 →

Single
Replacement
•Make new cmpd
•Flip and Drop + / -
•Check if new element
is diatomic
Ex 3) Cu (II) + AgNO3 →
Cu2+ NO31- + Ag
What type of rxn?
Single
Replacement
•Make new cmpd
•Flip and Drop + / -
•Check if new element
is diatomic
Ex 3) Cu (II) + AgNO3 →
Cu2+ NO31- + Ag
Cu(NO3)2 + Ag (not diatomic)
What type of rxn?
Single
Replacement
•Make new cmpd
•Flip and Drop + / -
