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...

question 3 please
The first 5 questions refer to finding solutions to the equation exp(w) = 3.8 ln(1+x). You will need to write it in the form f(x)-0, and use various root finding methods. 1. (10 pts) Plot the curves y- exp(Vx), and y 3.8 ln(1+x) on the same graph in the range 0 x 6. Read off intervals in which there are roots of the equation exp(k)- 3.8 In(1+x) Now find the roots to 6 decimal places using the...

To determine the salt formed during a neutralization reaction, combine the anion formed by the dissociation of the acid and the cation formed by the dissociation of the base in a ratio that results in a neutral, ionic compound. For example, if you have a cation with a 1+ charge and an anion with a 2- charge, you will need two cations to balance the charge. [(1+ charge on cation)(2)]+[2 - charge on anion)(1)] = (+2) + (-2) = 0...
