omg omg I'm like so stup. something times (thing/thing) = something. how can I be so stupid...

like many people have done with their calculators, I was dividing 987654321 by 123456789. and I realized... sum(0 to N) 987654321 * 10^(N*j) divided by sum(0 to N) 123456789 * 10^(N*j) where N can be any positive integer and j is in the real domain, there is a constant. Am I weird...

I've been trying to determine the concentration of a vegie oil (0.9 g/mL) in dilute(~2,4 w%) oil-water emulsions that are badly aerated and with gas bubbles. I tried the density method, weighing the samples and then vacuum suck them to rid the bubbles - in order to get an accurate volume...

Kraft Pulping -- H-factor what exactly is the H-factor? help? anyone?

dy/dt = ky, where k is a constant. y|[SIZE="1"]t=0 = 1; y|[SIZE="1"]t=10 = 4 I need to approximate k using the shooting method and Euler's method... please help.. :) wat's the procedure to approximate k using the shooting method :confused:

I'm designing my lab and so I want a spectrometer to investigate reaction kinetics eh. I am looking for a data logging spectrometer that can keep the reaction at constant temperature. My teacher is probably going to buy it. Does anyone know what company makes good spectrometers? About a...

I think measuring the optical properties will be more accurate, but there will certainly be complications involved in keeping the reaction at constant temperature, etc. so measuring pH change will be more simple. Is there a reaction that comes to your mind? Thnx in advance for helping me :)

I'm studying homogeneous catalysis and reaction kinetics, and I want to conduct an experiment that measure the rate of reaction by either: 1. a pH change or 2. consumption or generation of a compound bearing optical properties. Which one is more feasible? Hopefully you'll suggest a nice...
