A Lab experiment on how to determine the enthalpy change of the decomposition of Calcium Carbonate

The hydrogen Change of the Decomposition of calcium CarbonateIntroductionResearch Question:What is the love content modify of the decomposition of calcium carbonate? punctuate:Enthalpy in chemistry can be thought process of as the animation contained within the stupefys, or the internal zippo, al genius it is non heat and you can only measure reassigns in it. When beat bonds break in the reactants free qualification is given off, when bonds form, energy is absorbed. If the energy absorbed is less than the energy released, then the reaction is destructive-metabolic and the products are more stable than the reactants and vice versa. But, the enthalpy, or change in energy, of some reactions are too difficult to detain out in a standard laboratory due to toxins released or conditions that cannot be met in simple laboratory. Thus, that?s where Hess?s Law comes in as it states that if you go from the reactants to the products in one and only(a) reaction or many int ermediate steps, the overall energy change is still the same. In this experiment, Hess?s law will be utilized to calculate the decomposition of atomic number 20 carbonate. Calcium carbonate is a fairly stable compound, thus, it must admit that more energy goes into this reaction than out to produce the desire results.

CaCO3(s)CaO(s) + CO2 (g)It is the enthalpy change of this reaction that this experiment was wise(p) to find. Of course, another route must be used to master this, so HCl is added to CaCO3 and to CaO, and then, through some calculations and the equation = M * C * can the enthalpy of the decomposition of calcium carbonate be found. CaCO3 + 2HCl CaCl2 + CO2 + H2OCaO + 2HCL CaCl2 + H2OThese two re! actions will be done in a polystyrene beaker so no heat is released. But for the fighting reaction above, the opposite of the...
