in single displacement reactions, one chemical species replaces a part of another chemical species whereas, in double displacement reactions, exchange of two ionic species between two molecules occur.
<h2><u>Similarities</u><u>:</u></h2>
A single replacement reaction occurs when one element replaces another element in one compound. This type of reaction is represented by: A + BC → B + AC. A double replacement reaction occurs when two ionic compounds exchange ions, producing two new ionic compounds.
