Explore the chemistry of flameless ration heaters (FRH) with this 6-activity demonstration kit. Students observe the physical and chemical properties of FRH components and, together with the observed corrosion reaction, use this information to identify the reactants and products for a balanced FRH reaction. Great activity for teaching chemical reactions or as an introduction to thermochemistry. Extension activities are included. Materials are sufficient for the 6 demos to be performed 5 times.
