Question

irrelevant answers would be reported. difference between displacement reaction and double displacement reaction.(3 marker ) so answer as per​

Answer 1

Answer:

1.In a displacement reaction, a more reactive element replaces a less reactive element from a compound

Equation: CuSO4 (aq) + Zn (s) ZnSO4 + Cu

2.In a double displacement reaction, two atoms or a group of atoms switch places to form new compounds.

Equation: AgNO3 (aq) + NaCl (aq) AgCl (s)+ NaNO3 (aq)

Answer 2

Answer:

The reaction in which an atom or a set of atoms are displaced by another atom in a molecule is called displacement reaction. For instance, when Iron is added to a copper sulfate solution, it displaces the copper metal.

A + B – C → A – C + B

The above equation exists when A is more reactive than B.

The reaction in which two atoms or a group of atoms are displaced by another atom in a molecule is called a double displacement reaction.
