double displacement​

Answer 1

Examples of Double Replacement Reactions

is a double replacement reaction. The silver traded its nitrite ion for the sodium's chloride ion. Another example is the reaction between sodium sulfide and hydrochloric acid to form sodium chloride and hydrogen sulfide: Na2S + HCl → NaCl + H2S.

Answer 2

Answer:

A single-displacement reaction, also known as single replacement reaction or exchange reaction, is a chemical reaction in which one element is replaced by another in a compound.

A double displacement reaction is a type of chemical reaction in which the reactant ions exchange places to form new products. Usually, a double displacement reaction results in precipitate formation. The chemical bonds between the reactants may be either covalent or ionic.
