==Key Stage 3=====Meaning===A [[Word Equation]] is a way of representing [[Chemical Reaction|chemical reactions]] to show the [[Reactant|reactants]] and [[Product|products]] using words. ===About Word Equations===: In a word equation the [[reactant]]s are on the left and the [[product]]s are on the right.: Word equations can be used to show the names of [[chemical]]s before and after [[Chemical Reaction|reactions]] but they do not show the numbers of [[molecule]]s or the number of [[atom]]s in each [[molecule]]. For that information you need a [[Balanced Symbol Equation]].
