Predicting Products of Chemical Reactions

This worksheet is designed to help you predict products of simple reactionsof the four basic reaction types (synthesis, decomposition, singlereplacement, and double replacement.

For the first few reactions, the type of reaction is listed, you should predictthe products, then balance. Further questions just have the reactants listedand you should decide on the type of reaction, as well as the correctproducts.

Although states (s, I, g, aq) of the reactants and products are very important in achemical reaction, don't worry about determining those for these problems. Rather,focus on what products might result from the reactants given. Pay particular attention tothe ionic charge of species that you know form ions with only one possible charge (e.g.,alkali metals, alkaline earth metals, halogens, etc.)

1. Synthesis: Mg + 12 --4

2, Double displacement: CuCl2 + H2S -->

3, Double displacement: NaOH + HClO4 --e
