In this experiment, you will determine and compare the quantity of heat energy released in three exothermic chemical reactions through application of Hess’s law. Reaction 1: NaOH(s) → Na+(aq) + OH-(aq) + x1 kJ Reaction 2: NaOH(s) + HCl(aq) → H2O(l) + Na+(aq) + OH-(aq) + x2 kJ Reaction 3: NaOH(aq) + HCl(aq) → H2O(l) + Na+(aq) + OH-(aq) + x3 kJ In order to accurately measure the heat released in each reaction, we will be using a calorimeter. As...
Sodium metal reacts with water to produce hydrogen gas and sodium hydroxide according to the chemical equation shown below. When 0.030 mol of Na is added to 100.00g of water, the temperature of the resulting solution rises from 25.00°C to 37.90°C. If the specific heat of the solution is 4.18 J/(g · °C), calculate ?H for thereaction, as written.2 Na(s) + 2 H2O(l) --> 2 NaOH(aq) + H2(g)?H= ?Answer is one of the following:-90.0 kJ-360 kJ-5.41 kJ-180 kJ
