Question

(Section-B)
Q.6- What is the difference between
displacement and double displacement
reactions? Write chemical equations for
these reactions.
(2)​

Answer 1

Answer:

In a displacement reaction, a more reactive element replaces a less reactive element from a compound. In a double displacement reaction, two atoms or a group of atoms switch places to form new compounds. In a displacement reaction, one displacement takes place.

Answer 2

Answer:

$\huge\tt\underline{Question}$

wha is the difference between displacement and double displacement reactions?write chemical equations for the reactions.

$\huge\tt\underline{Answer}$

difference between displacement and double displacement reactions are:

$\huge\tt\underline{displacement}$

➭A displacement reaction is a chemical reaction where a chemical species in a molecule is replaced by another chemical species.

➭one chemical species is displaced.

➭one chemical species is replaced.

➭occur based on the reactivity of the chemical species.

$\huge\tt\underline{double\: displacement}$

➭ a double displacement reaction is a chemical reaction that involves the exchange of two ionic species between two different molecules.

➭two chemical species are displaced.

➭ two chemical species are replaced.

➭ occur where exchangeable ions are included in compounds.

$\huge\tt\underline{chemical\: equation}$

1)displacement reaction

ꨄ︎ Mg+2HCI ➜MgCI²+H²

2) double displacement reaction

ꨄ︎ HCI+HaOH ➜ NaCI+ H²O

$\huge\tt\underline{note}$:

many reactions including precipitation and neutralization use the double displacement mechanism.
