Evaluating An Enthalpy potpourri That Cannot Be Measured Directly. Evaluating An Enthalpy revision That Cannot Be Measured Directly. Dr. Watson. Introduction. We were told that atomic number 11 hydrogencarbonate decomposes on heating to picture sodium carbonate, water and carbon dioxide as shown in the equivalence below:- 2NaHCO3(s)--------> Na2CO3 (s) + H2O (l) + CO2 (g) = DeltaH1 This was given over as deltaH1 and we had to figure out as part of the experiment. This nevertheless cannot be measured directly, nevertheless can be put using the enthalpy changes from devil other reactions.
These being that of sodium hydrogencarbonate and hydrochloric acid and also sodium carbonate and hydrochloric acid. We were given a list of instructions in how to carry out the experiment, which are given later. List of tool Used. 1 x 500ml Beaker. 1 x Thermometer(-10 to 50oC). 1 x Polystyrene Cup. 1 x slowness Balance. 1 x Weighing Bottle. 10 grams of Sodium Hydrogencarbonate. 10 grams of Sodium...
