2. Two analytical chemists have reported a method for monitoring the concentration of SO₂ in air. They compared their method to the standard method by analysing urban air samples collected from a single location. Samples were collected by drawing air through a collection solution for 6 min. Shown here is a summary of their results with SO₂ concentrations reported in mL/m³. standard method: new method: 21.62 22.20 24.27 23.54 24.25 23.09 21.02 21.54 20.51 24.62 25.72 21.54 22.31 21.30 Using an appropriate statistical test determine whether there is any significant difference between the standard method and the new method at a = 0.05.

The development of lightweight batteries is an ongoing research effort combining many of the physical sciences. You are a member of an engineering team trying to develop a lightweight battery that will effectively react with O2(g) from the atmosphere as an oxidizing agent. A reducing agent must be chosen for this battery that will be lightweight, have nontoxic products, and react spontaneously with oxygen. Using data from Appendix I, suggest a likely reducing agent, being sure these conditions are met. Are there any drawbacks to your selection?
Using Table 17.1, calculate E° for the reaction between (a) lead and silver nitrate ion to produce lead(II) nitrate. (b) oxygen and iron(II) ions to produce water and iron(III) ions. (c) sulfur and nitrogen oxide gas in basic solution to form nitrate and sulfide ions.
Aluminum is produced commercially by the electrolysis of Al2O3 in the presence of a molten salt. If a plant has a continuous capacity of 1.00 million A, what mass of aluminum can be produced in 2.00 h?
The mass of three different metal electrodes, each from a different galvanic cell, were determined before and after the current generated by the oxidation-reduction reaction in each cell was allowed to flow for a few minutes. The first metal electrode, given the label A, was found to have increased in mass; the second metal electrode, given the label B, did not change in mass; and the third metal electrode, given the label C, was found to have lost mass. Make an educated guess as to which electrodes were active and which were inert electrodes, and which were anode(s) and which were the cathode(s).
