Part A. Calculate the pH in 0.025 M H2SO3 (Ka1 =1.5 x 10^-2, Ka2
= 6.3 x 10 ^-8).
Part B. Calculate the concentration of H2SO3, HSO3^- , SO3^2-,
H3O^+, OH^- in 0.025 M H2SO3.

2. Use MINITAB to generate 10,000 observations from a binomial
distribution with n = 50 trials and probability of success p = 0.02
. Create a histogram of the 10,000 observations. Comment on the
shape of the distribution. Why does it makes sense for the
histogram to have this shape?

For the equation e^x =x+2,
(a) use the fixed point iteration method to determine its two roots
to eight correct decimal places (you may need to write this
equation in two different ways of x = g(x) in order to obtain these
two roots);
(b) numerically calculate the convergence rates for your converged
iterations; (c) compare these numerical convergence rates with the
theoretical conver- gence rates we presented in class (also see
Theorem 1.6 on page 38 of the textbook).
Use the provided concentrations and volumes to
calculate the moles of each reactant.
