The given redox reaction is to be balanced and whether it is a combination, decomposition, or displacement reaction is to be classified. Ca ( s ) + H 2 O ( l ) → Ca ( OH ) 2 ( a q ) + H 2 ( g ) Concept introduction: A redox reaction is a type of reaction that involves the change in oxidation number of a molecule, atom or ion changes due to the transfer of an electron from one species to another. The redox reaction can be classified into three types depending upon the number of reactants and products as follows: 1. Combination redox reaction 2. Decomposition redox reaction 3. Displacement redox reactions
