Chemical Reaction ANSWERV V A process that results in the interconversion of chemical substances so that at least one new substance is produced. Synthesis (Combination) Reaction ANSWERV V A chemical reaction in which two or more reactants are chemically bonded together to form a single product. Ex. A+B > ARB. *the product AB ofa synthesis reaction will always be a compound* Decomposition Reaction ANSWERV ¥ A chemical reaction in which one single reactant is decomposed, or broken down, to produce two or more simpler substances. Ex. AB > A+B. *The reactant AB of a decomposition reaction will always be a compound* Single Replacement/Displacement Reaction ANSWERV V A chemical reaction between an element and a compound in which the element replaces an atom (or a group of atoms) from the compound. Ex. X+AB> AX-B *Single-replacement reactions always involve two reactants -- one element and one compound. Likewise, there are always two products formed-- one element and one compound.* Double Replacement/Displacement Reaction ANSWERV ¥ a chemical reaction in which two compounds exchange parts to form two new compounds. The reaction between an acid and a base *All the reactants and all the products in a double-replacement reaction will always be compounds.*
