A single-replacement reaction is a chemical reaction in which one element is substituted for another element in a compound, generating a new element and a new compound as products. Mg 3 (PO 4) 2 and Al. Examples: - A + BC → AC + B - Example: Ca + H2O → Ca(OH)2 + H2 In this general reaction, element \(\ce{A}\) is a metal and replaces element \(\ce{B}\), also a metal, in the compound. A single-replacement reaction is a reaction in which one element replaces a similar element in a compound. CHEMISTRY SINGLE REPLACEMENT REACTION WORKSHEET REACTION CATEGORY SINGLE REPLACEMENT REACTION DESCRIPTION In these reactions, a free element reacts with a compound to form another compound and release one of the elements of the original compound in the elemental state.There are two different possibilities: 1.
