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...

Therefore, according law, the heat of reaction of the one reaction should be equal to the sum of the heats of reaction wo. This concept is sometimes referred to as the additivity of heats of reaction. The primary ob...

how to do part a, trial 1
Data Analysis Part A. 1. Calculate the specific heat for your metal for each trial. Remember that the heat lost by the metal is equal to the heat gained by the water in the calorimeter and by the calorimeter itself. This can be expressed as - metal (water + Jealorimeter). The specific heats are positive numbers. EXP 8 - Thermochemistry Trial 3 Trial Trial 2 Trial 3 Part C 2 40.408 g 109.536...
