Question

5 equations double displacement​

Answer 1

Double displacement reaction: The reactions in which two compounds react by exchanging ions and form two new compounds are called double displacement reaction.

Examples:

1)

$Pb{(NO3)}_{2} + 2KI \longrightarrow Pb{I}_{2} + 2K{NO}_{3}$

2)

$Ba{Cl}_{2} +{Na}_{2}{SO}_{4} \longrightarrow Ba{SO}_{4} + 2NaCl$

3)

$Ag{NO}_{3} + NaCl \longrightarrow AgCl + Na{NO}_3$

4)

$Ba{Cl}_{2} + Cu{SO}_{4} \longrightarrow Ba{SO}_{4} + Cu{Cl}_{2}$

5)

$Ag{NO}_{3} + NaI \longrightarrow AgI + Na{NO}_{3}$

Answer 2

Answer:

Double displacement reaction: The reactions in which two compounds react by exchanging ions and form two new compounds are called double displacement reaction.

Examples:

1)

Pb{(NO3)}_{2} + 2KI \longrightarrow Pb{I}_{2} + 2K{NO}_{3}Pb(NO3)
