Question

Q-4 What is the difference between displacement and double displacement reactions? Write
relevant equations for the above.​

Answer 1

Answer:

Explanation:

In displacement reaction, one element from its salt is displaced by a more reactive element e.g. in following example, Cu is displaced by Zn from CuSO4 because Zn is more reactive. In double displacement reaction, exchange of ions takes place between two reactants to form new products.

Answer 2

$<i> In a displacement reaction, a more reactive element replaces a less reactive element from a compound.</p><p>For Example: CuSo4 (aq) + Zn (s) → ZnSO4 (aq) + Cu (s)</p><p>In a double displacement reaction, two atoms or a group of atoms switch places to form new compounds.</p><p></p><p>For Example: Na2SO4 (aq) + BaCl2 (aq) → BaSO4 (s) + 2NaCl (aq)</p><p>$
