We reviewed the note which is about double replacement, combustion, neutralization and net ionic equations.

Double replacement

AB + CD -> CB+ AD

Eg. Na2CO3 +2KBr -> K2CO3 +2NaBr

Combustion

AB + O2 -> AO + BO

Eg. C4H8 + 6O2 -> 4CO2 + 4H2O

Neutralization

HA + BOH -> H2O + BA

Eg. HBr + Sr(OH)2 -> SrBr2 + 2H2O

Net Ionic Equations

Eg. KCl + AgNO3 -> KNO3 + AgCl

Total ionic equation : K+ (aq) + Cl-(aq) + Ag+(aq) + NO3-(aq) -> K+(aq) + NO3-(aq) + AgCl(s)

Net ionic equation : Ag+(aq) + Cl-(aq) -> AgCl(s)
