May be more than two products Opposite of synthesis Single Replacement One element replaces A + BC AC + B Zn + HCl → → another element in a H₂ + ZnCl₂ compound. If a stronger cation or anion is introduced to an ionic bond, then one part of the ionic bond will leave. Double Replacement Two compounds AB + BD AD + AC NaCl + KBr → produce two new NaBr + → compounds. KCl The positive 2 K(OH) + ions replace Pb(NO₃)₂ → each other. 2 K(NO₃)₂ + We can think Pb(OH)₂ about forming the products through FOIL. The inside and outside elements of the reactants will combine. Combustion A reaction that uses a CxHy + O₂ CO₂ + CH₄ + 2O₂ → hydrocarbon and H₂O CO₂ + → oxygen as reactants to H₂O create carbon dioxide and oxygen. A hydrocarbon must contain both hydrogen and carbon, and sometimes oxygen. Types of Reactants-
