Develop two functions in R, one that generates s^2 using the formation definition, and one that calculates s^2 based on the hand calculation equation. Generate data from a normal distribution. Use your functions to calculate s^2 for your generated data. Try this for various variances so that your data become closer and closer to the mean (less variance). What do you find, comment.

Consider the following model of interacting species: R' = R(2 + 3R − S) S' = S(1 − S + 4R) (a) Find all the equilibrium points, and determine the type of those points which are in the first quadrant (including those on the axes) (b) Plot the phase portrait of the system. (c) If the initial conditions are R(0) = 1 and S(0) = 1, what will be the population size of each species when t → ∞?

Why would it be unreasonable to study the enthalpy of formation of Mg0(s) by directly using your Styrofoam calorimeter? Why is Hess's law a good way to study this reaction? Give one other example of a reaction that could not be studied using a Styrofoam container. (Hint: What solvents are used dissolve polystyrene?)
