In a chemical reaction atoms break and form
WebThe simplest form of an exchange reaction might be: A + BC → AB + C. Notice that, to produce these products, B and C had to break apart in a decomposition reaction, whereas A and B had to bond in a synthesis reaction. A more complex exchange reaction might be: AB + CD → AC + BD. Another example might be: AB + CD → AD + BC.
