A double replacement reaction is a type of chemical reaction where two compounds react to form two different compounds by exchanging ions. This reaction can be represented by the general equation:
A(B) + C(D) → A(D) + C(B)
Key Characteristics of Double Replacement Reactions
Ionic Compounds: Double replacement reactions typically occur between ionic compounds. These compounds are made up of positively and negatively charged ions.
Acid-Base Neutralization: Double replacement reactions can also involve the neutralization of an acid and a base to form water and a salt.
Example of Double Replacement Reaction
An example of a double replacement reaction is the reaction between silver nitrate (AgNO3) and sodium chloride (NaCl) to form silverchloride (AgCl) and sodium nitrate (NaNO3):
AgNO3 + NaCl → AgCl + NaNO3
General Steps for Predicting Double Replacement Reactions
By mastering these concepts and practicing with different examples, you can gain a solid understanding of double replacement reactions and successfully predict the products of such reactions.

Energy - A. Energy is involved in all physical and chemical processes. It is conserved, and can be transformed from one form to another and into work. At the atomic and nuclear levels energy is not continuous but exists in discrete amounts. Energy and mass are related through Einstein's equation E=mc 2 . B. The properties of atomic nuclei are responsible for energy-related phenomena such as radioactivity, fission and fusion. C. Changes in entropy and energy that accompany chemical reactions influence reaction paths. Chemical reactions result in the release or absorption of energy. D. The theory of electromagnetism explains that electricity and magnetism are closely related. Electric charges are the source of electric fields. Moving charges generate magnetic fields. E. Waves are the propagation of a disturbance. They transport energy and momentum but do not transport matter.
