Having now got official word and examples from the test committee (thank you!!!!!), I am delighted to be able to move on to more positive thinking about the new question #4. I am curious about the new requirement to balance. The way I see it is this; I think that this may eliminate (or at least make very difficult) several equations from the (traditional) list. For example I think students will find it VERY difficult to do meaningful balancing of many complex redox reactions. Consider complex redox reactions that involve hydrogen peroxide, disproportionation, non-metal halides in water and it even puts organic combustion reactions in a slightly different light (previously a guaranteed 2 out of 3 points, now not so quick). Even things that are very common like the use of dichromate (VI) and manganate (VII) in redox chemistry that are relatively easy to balance will take on a whole new light for some kids. I think what I am trying to say is that the balancing of many of the traditional equations in question #4 will be beyond many students. It so happens that the 2006 set do not really reflect this concern as most of them are equations that do not fit into this “difficult to balance” category. I think this may be a window into the future – I guess we’ll see! In addition, with the removal of choice I feel we are bound to see a trimming of the traditional list to a more manageable set of “traditionally asked” equations.
