11 – Rev. July, 2015How to recognize the types of
reactions:Synthesis:Generally, the reactants are elements and forms
a compound as product.Decomposition:A compound is the reactant that
forms two or more products. One or more or the products
areelements.Single Replacement:An element reacts with a binary
compound or salt, making a displacement of one element of
thecompound with the elemental reagent.Double Replacement:Two
binary compounds or salts reacts between themselves, interchanging
their atoms or ions.Neutralization:An acid (a compound with H+ ion)
reacts with a base (a compound with OH- ions) to form a salt
andwater (H2O).Combustion:A compound reacts with oxygen (O2) to
produce carbon dioxide (CO2) and water …
