4. You will conduct the two solvation reactions and three neutralization reactions in this experiment. In the space provided below, write the balanced net ionic reaction equations from the descriptions. Use the table of thermodynamic data in your text (AHf(NaOH(s)= -425.61 kJ-mol) to calculate the molar enthalpy of the reactions. These will be the accepted values you will compare to the experimental values you calculate using data collected during the experiment. Part I: Solid sodium hydroxide is combined with water...

10- Hess Lab Section: eriment Nine - Endo-and Exo-Thermic Reactions: Hess's Law troduction experiment, you will use a Styrofoam-cup calorimeter to measure the heat released by three rea the reactions is the same as the combination of the other two reactions. 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...
