Precipitation reactions and neutralization reactions are two common types of double replacement reactions. Note that double replacement reactions can be written as molecular, complete ionic, or net ionic equations. Single replacements reactions are only possible if the reactant element in the reaction is more reactive than the element in the reactant compound. Double displacement reactions are those in which the reactant compounds exchange positive ions with each other to form new compounds. This happens when chemicals dissolved in a solution are mixed together and an insoluble solid, known as a precipitate, forms in the liquid mixture. Burning wood.
