If the answer is not available please wait for a while and a community member will probably answer this soon. The reaction in the green box below is a prototype (that means A's and B's stand for elements) of a typical synthesis reaction, a reaction in which atoms or smaller molecules combine to form one or more larger or more complicated compound(s).. Before we go on to some examples, let's use this reaction to take care of some basic reaction terminology. 14. A general combination reaction can be represented by the chemical equation given here. The products of a decomposition reaction are determined largely by the identity of the anion in the compound. Since the analysis of a compound takes place using light energy or in other words photons therefore such reactions are called photolytic reactions. Thermal decomposition reactions. Since the analysis of a compound takes place using light energy or in other words photons therefore such reactions are called photolytic reactions.
