What is the general equation and an example equation for a Double Replacement Reaction in chemistry?
gpt
AB + CD ----> AD + CB, or compound + compound --> compound + compound; examples include Pb(NO3)2 + 2KI --> PbI2 + 2KNO3, FeS + 2HCl --> FeCl2 + H2S, and HCl + NaOH --> H2O + NaCl.
Explanation: Double Replacement Reactions, also called metathesis reactions, occur when two compounds are exchanged and each compound is swapped with the partner's other compound.
