Question

define double displacement and give two chemical equations

​

Answer 1

Answer:

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

1. Na2S+2HCl→2NaCl+H2S

2. CuCl 2(aq) + 2 AgNO 3(aq) → Cu(NO 3) 2(aq) + 2 AgCl(s)

Answer 2

Answer:

a double displacement reaction is a reaction in which positive and negative ions of two ionic compounds exchange places form New compounds
