Self-sufficient - nothing additional is needed. No electricity, no gas, no fire and still a hot meal. s: solid; l: liquid; g: gaseous; aq: in solution; the vertical arrow indicates that gas is released. any pyrolysis reaction a reaction of neutralization Thermite reaction of iron rusting (rust steel wool with vinegar). a reaction between calcium chloride and water Is the reaction between NaOH and HCl endothermic or exothermic? The best result within the context of the LNCU project (see box) was achieved by filling a small beaker with water and placing it in a larger beaker with a layer of styrofoam in-between for insulation. The students then placed the calcium chloride, to which they had added very little water, in a small film canister. Attaching a string to it and a stone for weight, they let it hang into the water.
