llbm Calculations - Day 2

The day 2 lesson of llbm calculations involved the quadratic equation.

The quadratic equation approach was necessary as
the K expression was no longer a perfect square.

A complete solution for these questions will include:
 - completed ICE chart
 - llbm law (the K expression)
 - substitution into the K expression
 - necessary work to get to the quadratic equation
 - the quadratic equation itself
 - both possible values of "x"
[indicate which value is 'invalid' - sub into the llbm expression on the ICE chart]
 - final answer - where various llbm conc have been determined.

 Three tedious questions to complete for homework.
p480(9) and p481(4,5)

The text also works through some examples. Check out the text too.

Have you complete the clock reaction lab yet?

Soon, very soon the lab will be marked and returned.
You may want to be one of those people who gets the lab returned to them.

Soon to be loaded on moodle. The next lab - Quantitative Equilibrium.
There is some pre-lab calculating to do. If you wish to work ahead. The lab
document has three parts to it. Two of the three parts will be loaded up in a
few minutes. The last part rquires scanning - and that will not happen until later
this evening.

Solutions to old homework can also be found on moodle. At this point,
the recent llbm calculations have not been revealed. Something about
having the kiddies work through it first, before seeing the solutions.

Why are gold fish orange? [Ans: The water makes them rusty.] Who held the baby octopus ransome? {Ans: Squidnappers]. Okay, off to upload a few things to moodle.
