The reaction, KOH(aq)+HCl(aq)→KCl(aq) + H2O(l)is an example of a double displacement reaction.
Consider the reaction :
KBr(aq)+AgNO3(aq) ⟶ KNO3(aq)+AgBr(s)
This is an example of :
(a) decomposition (b) combination reaction
(c) double displacement reaction (d) displacement reaction
Fe2O3 + 2Al → Al2O3 + 2Fe
This reaction is an example of :
