Explore the chemistry of flameless ration heaters (FRH) with this 6-activity demonstration kit. Disassemble an FRH and demonstrate the physical properties of its components. Collect the gas evolved from a micro version of the FRH reaction to identify 1 of the products of this reaction. Test the pH to help identify another of the products. Test the identity of the salt used to accelerate the FRH reaction via a precipitation reaction. Use a flame test to identify the metals in the FRH. Finally, demonstrate the dramatic temperature increase inside an activated FRH. Students use the data and observations gathered during these demos to identify the reactants and products of this corrosion reaction and write a balanced equation for the FRH reaction. Great activity for teaching chemical reactions or as an introduction to thermochemistry. Extension activity ideas are included. Materials are sufficient for the 6 demos to be performed 5 times.
