,double replacement(复分解反应) ,single replacement
请翻译并解释是什么反应方程!

Single Replacement(Displacement)就是置换反应.
This type can best be shown by examples in which one substance is displacing another.
EG. Fe(s)+CuSO4(aq)→FeSO4(aq)+Cu(s)
Double Replacement(Displacement)就是复分解反应
This type of reaction is called because there is an actual exchange of “parterns” to form new compounds.
EG. AgNO3(aq)+NaCl(aq)→AgCl(s)+NaNO3(aq)
