what is displacement and double displacement?
Answers
Answer:
Displacement reaction is a chemical reaction in which a more reactive element displaces a less reactive element from its compound. Both metals and non-metals take part in displacement reactions. Example : Reaction of iron nails with copper sulphate solution.
Explanation:
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, Na2S+2HCl→2NaCl+H2S.
Answer:
In a double displacement reaction, two atoms or a group of atoms switch places to form new compounds. ... Salt solutions of two different metals react with each other. Examples: 2KI + Cl2 → 2KCl + I2 is a displacement reaction. CuSO4 + Zn → ZnSO4 + Cu is also a displacement reaction.
