Que 5 which could be the answer

Answer 1

Answer:

A double displacement reaction, also known as a double replacement reaction or metathesis, is a type of chemical reaction where two compounds react, and the positive ions (cation) and the negative ions (anion) of the two reactants switch places, forming two new compounds or products.

Step-by-step explanation:

The reaction between silver nitrate and sodium chloride is a double displacement reaction. The silver trades its nitrite ion for the sodium's chloride ion, causing the sodium to pick up the nitrate anion.

AgNO3 + NaCl → AgCl + NaNO3

Here's another example:

BaCl2(aq) + Na2SO4(aq) → BaSO4(s) + 2 NaCl(aq)

Answer 2

Answer:

The type of reaction in which two compounds react by an exchange of ions to form two new compounds is known as Double displacement reaction . For example :-

Reaction between sodium nitrate and sodium chloride  

                      AgNO3 + NaCl = AgCl + NaNO3
